Inteligência Artificial

Botando uns pingos nuns is…
(English version below)

O que acham que é?

ChatGPT e afins.

O que é?

Um campo de estudo sobre métodos para fazer com que o computador tome decisões “espertas” com mínima ou nenhuma intervenção humana.

O chatGPT é uma ferramenta que foi construída com um desses métodos. Por ela ser fácil de acessar e usar, e pela qualidade das respostas, é uma ferramenta que se popularizou muito. Mas ela é uma de muitas outras ferramentas usando um de muitos outros métodos da área de inteligência artificial.

O chatGPT é inteligente mesmo?

Não. O chatGPT é um jogo de probabilidades. Vou tentar explicar com uma analogia.

Imagina que você memorizou todas as obras da grécia antiga, em grego, sem saber falar grego. Ou seja, você sabe todos os símbolos, em todos os documentos, e a ordem que eles aparecem, mas não faz a menor idéia do que eles significam.

Aí alguém escreve pra você uma pergunta em grego antigo. Você vê aqueles símbolos e, sem saber o que significa, vai procurar em todos os outros símbolos que você memorizou se tem alguma coisa parecida. Aí você acha umas coisas similares e começa a construir uma reposta. Primeiro escolhe uma palavra que geralmente segue aquela pergunta, ou perguntas muito parecidas (porque têm muitos símbolos em comum). Daí você dá uma pesquisada no que geralmente segue aquela palavra, e escolhe a segunda aleatoriamente dentre os candidatos mais prováveis, e assim por diante.

É uma idéia simples, implementada muito complexamente com várias transformações de símbolos pra números (porque é mais fácil pro computador trabalhar com números), e que funciona incrivelmente bem. Mas que, na minha opinião, diz mais sobre a nossa regularidade e padrões existentes em tudo que a gente produz do que sobre um computador sendo mesmo inteligente.

É perigoso?

A tecnologia por ela mesma, não. A tecnologia na nossa mão descuidada, provavelmente sim. Mas essa é a história da humanidade. As tecnologias surgem, todo mundo fica empolgado e espreme tudo que pode delas até as coisas começarem a dar errado, e aí a gente pensa como consertar. Foi assim com a agricultura, com os carros, com a internet (que ainda não foi consertada, mas já deu ruim), e vai ser assim com a inteligência artificial. Tem potencial pra dar certo, e potencial pra dar errado, mas não temos o tempo (ou talvez a calma) pra refletir antes da coisa se popularizar e ser usada pra diversas tarefas, boas e más.


Artificial Intelligence

Crossing some t’s and dotting some i’s…
(Versão em português acima)

What do people think it is?

ChatGPT and family.

What is it?

It is a field of study about methods for computers to make “smart” decisions more or less autonomously.

ChatGPT is a tool built using one of those methods. As it is easy to access and use, and for the quality of answers, it has become widely popular. But it is one of many tools based on one of many methods from artificial intelligence.

Is chatGPT really intelligent?

No. ChatGPT is a probability game. I will try to explain using an analogy.

Imagine that you have memorized all the works from ancient Greece, in Greek, without knowing Greek. That is, you know all the symbols, in all documents, and the order in which they appear, but you have absolutely no idea what they mean.

Then someone sends you a question written in ancient Greek. You see those symbols and, without knowing their meaning, look for similar sequences of symbols among the ones that you have memorized. You find some similar stuff and start building an answer. First you choose a word that typically follows the question symbols or sequences like it. Then you search what usually follows that word, and choose a second one randomly among the more likely candidates, and so on and so forth.

It is a simple idea, implemented in a very obscure way with many transformations from symbols to numbers (because it is easier for computers to work with numbers), and that works amazingly well. However, in my opinion, this says more about our regularity and patterns existing in everything we have produced, than about a computer being actually intelligent.

Is it dangerous?

The technology in itself, no. The technology in our careless hands, probably yes. But this is the history of mankind. Technologies arise, everyone gets excited about it and use it to its limit until things start to go wrong, and then we think how to fix it. It was like this with agriculture, cars, internet (which we did not fix yet, but it already went wrong), and it will be like this with artificial intelligence. It has the potential of being a good or a bad thing, but we do not have the time (or perhaps the patience) to reflect before it becomes too popular and used for all sorts of things, good and bad.


P.S.: AI likes my post about AI 😂

Sobre debates produtivos

Nessa época de eleições, ocorrem debates entre candidatos na TV. Na sua maior parte, esses eventos acabam sendo uma oportunidade para a troca de insultos e propaganda grátis, e raramente representam um debate de fato. Debates, na verdade, fazem parte dos primórdios da lógica, e, logicamente, o objetivo nunca foi insultar o adversário ou enaltecer o aliado. Em um debate existem sim dois (ou mais) lados: o proponente e o oponente, em termos técnicos. O papel do proponente é propôr uma idéia, e o papel do oponente é desafiar essa idéia.

Pode parecer uma atividade combativa, mas não é. No final das contas, o objetivo é entender se a idéia é válida, ou em que condições ela seria válida. E isso só se descobre colocando essa idéia em cheque de todos os modos possíveis. O objetivo é aumentar o entendimento de todos sobre aquela idéia, e não “vencer” (seja lá o que isso significa) ou “convencer o outro”.

Na prática, debates (produtivos) entre dois lados aparentemente contraditórios servem para:

  1. Cada lado entender um pouco mais das motivações do outro, e
  2. fortalecer ou refinar os argumentos que a gente tem sobre algum assunto (ou seja, aprender).

Quando um lado faz pergunta pro outro o objetivo não é desafiar ou discordar, mas entender (ponto 1). E quando a gente tem que explicar nossas convicções pra outras pessoas, temos que pensar porque temos essas convicções e em que elas são baseadas (ponto 2). Ou seja, um debate produtivo contribui para o aumento do entendimento global. Infelizmente, as pessoas costumam reagir muito mal a qualquer questionamento que pareça desafiar suas afirmações ou exija um pouco de reflexão. E acabamos assim, com “debates” onde cada um fala pra si próprio, e ninguém realmente aprende.

Eu senti necessidade de esclarecer isso depois de muitas e muitas tentativas frustradas da minha parte de discutir política com algumas pessoas. Eu já discuti muito política na vida. Sinceramente, no início eu não sabia de muita coisa (eu continuo não sabendo, mas a curva é monotonicamente crescente). Mas a gente ouve as outras pessoas, faz perguntas, desafia suposições, pesquisa na internet… E nesse caminho eu aprendi muito. Lembro de discussões muito interessantes e produtivas sobre inflação, cotas nas universidades, voto obrigatório, aprovação de leis, corrupção (e as motivações e implicações sociais), índices econômicos, PIB… enfim. Uma variedade de assuntos! E um tanto de gente bem intencionada me ensinou muito sobre essas coisas durante discussões. Seja sobre partes técnicas do assunto que eu de fato ignorava, seja sobre consequências ou causas que eu não tinha considerado, ou sobre outras opções que eu nem sabia que existia. E talvez elas também aprenderam um pouco no processo, nem que seja como explicar as coisas que elas sabem de modos diferentes. E nem sempre a gente concordava no início, e nem sempre concordava no final. Mas isso não importava.

Infelizmente a coisa ficou feia de uns anos pra cá, e ninguém mais parece ter saco pra isso. Eu tentei, com a melhor das intenções possíveis, pedir uma elaboração de argumentos, perguntar, ou apresentar contra-exemplos a várias pessoas que me apresentaram idéias das quais eu discordo. E é muito, mas muito frustrante mesmo, quando alguém vira e fala “mas é minha opinião e eu não vou mudar e você não vai mudar então essa discussão é inútil”. Quer me matar de raiva é terminar um assunto assim. Cá estou eu, tentando entender o que pra mim parece incompreensível, e ninguém disposto a explicar a não ser com argumentos vazios e sem fundamentos. E que, ao invés de refletir sobre ou fortalecer seus argumentos quando eu faço perguntas, fecha a cara e vai embora. Isso pra mim não é opinião, é teimosia e preguiça de aprender. E se não quer aprender sobre um assunto ou fundamentar suas opiniões devidamente, não me venha apresentar ele como se fosse “a sua verdade”. Conhecimento não é fé.

10 years away from Brazil / 10 anos fora do Brasil

Portuguese version below.

I realized today that it has been 10 years since I moved away from Brazil. March 2011 was when I moved to Vienna, Austria, to pursue a PhD degree. At the time, 10 years sounded like an eternity. Now that they have passed, it doesn’t feel that much. I was reflecting today about an interesting phenomenon that unfolded slowly, and I think it conveys a good picture of the country I once called home.

The first few times I visited Brazil after moving, I was usually asked “so when are you coming back?”. Everyone assumed I was away to study, and that I would go back as soon as I graduated. After a couple of years, I started being told by several people “you know, perhaps it is better you stay abroad a little longer”. Everyone was a bit more pessimistic, talking about how bad the country was. When I got a job at CMU, a lot of people asked if I could use this a chance to stay in the US for good. This year, with the pandemic, I am considering whether to visit Brazil in June/July (I am fully vaccinated). When mentioning that, I got “don’t come, things are a mess here”. 😢


Hoje eu percebi que fazem 10 anos desde que eu me mudei do Brasil. Em março de 2011 eu fui fazer meu doutorado em Viena, na Áustria. Na época, 10 anos parecia uma eternidade. Agora que eles já se passaram, não parece muito. Eu estava refletindo hoje sobre um fenômeno interessante que foi acontecendo aos poucos, e que, na minha opinião, reflete bem o país que um dia foi minha casa.

As primeiras vezes que eu visitei o Brasil depois de ter me mudado, a pergunta que eu mais ouvia era: “quando você volta?”. Todo mundo assumia naturalmente que eu só ia terminar meu doutorado e voltar. Depois de uns dois anos, antes de eu terminar o doutorado, o discurso mudou pra “talvez seja melhor que você fiquei aí mais um tempo”. Eu lembro que ainda estava em Vienna quando todo mundo começou a ficar mais pessimista, falando só dos problemas do Brasil. Quando eu consegui o emprego na universidade americana onde eu trabalho, muitas pessoas me perguntaram se tinha possibilidade de eu me mudar pros Estados Unidos de vez. Esse ano, com a pandemia, eu estou cogitando visitar o Brasil em Junho ou Julho (já tenho as duas doses da vacina, e há dois anos que não vejo minha família). Quando eu falei isso, a resposta foi “não vem, está um caos isso aqui”. 😢

About choices and tech

Do you waste hours scrolling through infinite feeds on your favourite app? Did you check your e-mail for the 100th time today? Did you stop an important task you were doing because your phone vibrated? Did you stop paying attention to someone you were talking too because of a pop-up notification on your desktop? If any (or all) of those seem familiar, I suggest you watch the documentary The Social Dilemma (see trailer) on Netflix. I think this hits the nail on the head when it comes to problems exacerbated by new technology which I was trying to talk about in a previous post.

I really like the way the problem is framed, and I feel somewhat relieved that my resistance to social networks might not be an indication of a character flaw. It also puts in check a general belief that we are in control of our thoughts and choices, something I have questioned over and over again. We are highly suggestible (maybe gullible?) animals and new technology just found out a way to make specific targeted suggestions with microscopic precision. New apps change our habits, the way we think, the way we work, the way we relate to each others, and we don’t even realize it. Maybe you are happy with this situation, maybe you think there is no harm done, since you are getting access to content that you would never be able to see otherwise. But we are really biased for judging what is good for us… For example, we all know that eating too much fat or sugar is bad for our health, but we can’t resist that desert every now and then. If we were less aware of our health, we might think that sweets are good for us because they just taste so good… so what’s the harm? The same thing happens with all this new technology, except we are in uncharted territory, in all senses, and it is not really clear what is and isn’t healthy. So we must treat this with care, and we must be extra judicious when spending time online. Where are we spending time? Is this time well spent? Is there a competition for our attention that prevents us from focusing on one thing? Are we happier with ourselves after unplugging from the online world?

I am definitely not happy. We need to admit that choices are made *for us* and that we are not so much in control. We need to recognize that first, and try to fight it. But we should not fight this alone. It is unrealistic to believe everyone will suddenly have the will power to control how much time they spend online, and how. Like many other aspects of life, we need policies to protect us from ourselves. Like having salads before deserts in buffets, calorie counts on labels, sugar-free options… We need sugar-free internet. This will only happen with a big shift in how the industry operates. And this can be triggered by social demand.

It is not like I believe the big internet giants are evil. This story has happened several times before: we do first, and think second, when we realize the mistakes, we adapt. I hope we are realizing our mistakes, and I really hope we adapt before it is too late.

What happened?

Six months since I last wrote here, and the world is now upside down. It is not like it was not already messed up before, but this is a whole new level of mess… There are so many things going on, and so many things crossing my mind, that I find it hard to make sense and organize it all. So forgive me if this text is all over the place.

A bit of context if you are reading this too far in the future. The world is now 5 or 6 months in the SARS-CoV-2 pandemic. This is a highly contagious virus that causes a respiratory disease named COVID-19. For more on the topic, you can google it. There is, of course, a wikipedia page about it. The story told in the future about this depends on how we deal with it now. Only you, future person, can know what came out of it, but I must say that, for some of us people of the present, things are not looking good.

I started checking the news again since I am working from home and things are calmer on my side. Big mistake. It feels surreal. I end up asking myself “whaaat??!!” way too often. Here are a few recent headlines, just FYI:

In hindsight, we can hardly blame the virus alone for this chaos. We have put ourselves in this situation, it was a long time coming, and the health crisis is only making our problems more evident.

What happened to knowledge?

For starters, there was a *lot* of skepticism about the seriousness of this illness. In spite of all the warnings of the WHO, scientists, and epidemiologists, decision makers were still dismissive, thinking the studies were alarmists, and these scientists were an “opposition” of sorts. Maybe because mortality rate is not at 50%, and people are not visually sick, it was easy to look to the other side. Then, when things started to look bad, many decision makers put their faith in untested drugs, irresponsibly advertising them and encouraging distribution in hospitals. Even with no evidence that it would work, and a lot of evidence that it had serious side effects.

In my opinion, this is a result of two things: (1) a general distrust in science (e.g. climate change deniers, anti-vaccine movement, flat-earthers); and (2) an enhanced sense of entitlement for an opinion on each and every subject. Obviously these two things are not completely independent, but I think it is interesting to understand how this has come about, and ways to alleviate it. It seems people are unable to critically analyse information, and discern trustworthy sources. I don’t blame them. We can find literally everything on the internet nowadays disguised as reliable information. In a world where everything is true, each person picks their own truth. But you see, science doesn’t really work like that.

what happened to social security?

This reluctance to accept the studies was not a mere opposition to science. There is a very real and practical reason behind it: the economy. You see, all the studies indicated that, in order to curb the spread of the disease and prevent the collapse of health care systems, we needed to reduce gatherings, be more isolated and avoid contact with others. Now, people won’t stay at home because we politely ask them… Governments needed to take action. First thing to close are schools, then shops, then public spaces, and so on. Or at least that was the recommendation. The thing is, some people can move their business to home office, but a big number of people cannot. And with people at home, they don’t buy, they don’t travel, they don’t spend. And that means a lot of business lose income, which means they cannot pay their employees, which results in bankruptcy and unemployment. No government wants to deal with this problem, this is all very familiar, so why would they force business to close and the economy to slow down?

When have our lives become so dependent on an economy running and business working properly? Are we willing to continue this way? I mean, it is quite fragile as we can see now. Peoples’ subsistence depend on them having a job, but not all people have jobs all the time. So what happens when they don’t? That is what a social security system is for. We can compare the social impact of this pandemic in countries with high and low social security to see what a difference this makes. Of course this is hard given all the other factors, but it might be educational in any case. What cannot happen is for decision makers to look away so much because supporting the citizens in a time of need is just not possible (or not a problem they want to handle).

what will happen to us?

A(n optimistic) part of me wants this to be a lesson, that we look at it critically, find our weak points as a society, and fix them for the next emergency (let’s face it, another one is bound to happen sooner or later). The two topics above are simply things that worry me more, but I am sure there are all sorts of other problems that have become really obvious (like international collaborations, access to health care, inequality, to mention a few). A (realistic) part of me is hopeless that this will happen, specially when I see people so eager for things to “get back to normal”. Once again, we fall prey to our urgency and move forward in leaps and bounds (or as we say in Portuguese, aos trancos e barrancos).

About data

I have recently watched the documentary The Great Hack, which explains the Cambridge Analytica scandal: how they used a great amount of data from facebook to spread biased and fake messages and influence the outcome of Brexit and the US presidential election of 2016. The film focuses a lot on the role of big data-owning corporations such as facebook, google, or amazon (the usual suspects). It hints towards holding these companies responsible for what people do with the data they collect, and sort of portraits them as “evil”, but perhaps too much [1]. It also blames the technology and the “algorithms”, whatever those are. In my opinion, this is a very shallow analysis of what is actually going on, and I think they got it all upside down. Let me break down this problem into three parts.

The technique

People that do not understand what is going on behind the curtains of recommendation algorithms tend to see the spread of targeted manipulative information as an extremely bad thing (which it is), and how music streaming services that suggest music that you like as an extremely good thing (which it is). I am no expert in recommendation systems myself, but I know enough to know that the principles behind these two tasks are basically the same. So blaming and prohibiting the technique itself will mean that a lot of wonderful things we have today will no longer be available. And a huge field of research, which can be used for good, will go away. I don’t think this is a good direction to follow…

The data

Our data is being collected all the time. I know that, you know that, everyone knows that. It is because of this data, and the techniques, that we can talk to our phones, that we can search for a photo by a keyword, that our watches can measure our steps, and many other conveniences that make our lives today very comfortable. The corporations that collect and use the data to develop these wonderful things know how this is sensitive information, and how everything should be super anonymized if it is supposed to go into the hands of others (such as researchers).

In the case of Cambridge Analytica in particular, I think Facebook has actually little blame on this [1]. The story plays out like this. A researcher at Cambridge University developed an app and provided it to Cambridge Analytica. The company, in turn, used this app to do a survey and people had to agree that their data was going to be used for academic purposes. It turns out that, because of the way facebook was designed, the app also collected data from all the friends of the person taking the survey. Now, I think this is a serious design flaw, and whoever saw that, the researcher or whoever was working on this at Cambridge Analytica, should have at least informed facebook about it. Instead, they have exploited this to get all the data, and kept quiet. Needless to say, there was no “academic purpose” there. So facebook’s fault is this design flaw. They have openly apologized for that, and implemented more strict privacy rules (GDPR) since then. However, it is not fair to place the responsibility of how others used this data solely on them.

These big data companies tend to be already protective enough of their data. Ask any researcher that needs data how hard it is to get a fraction of what they have. So it is not like facebook is completely irresponsible and is just allowing anyone to tap into their pool. By the way, the researcher who developed the app was actually a consultant for facebook. Which makes me even more suspicious why he wouldn’t report such a breach in the first place.

The use

This is the crucial point in my opinion, and the point that is most overlooked. The problem, in the end, was not the existence of data or fancy techniques to process it. The problem is how this framework was used. And it is not like it was used for a super novel thing. The data was used for propaganda, and propaganda has been around for centuries. And people warning about the dangers of propaganda have also been around for a while now. For example, this quote from Everett Dean Martin: “Propaganda is making puppets of us. We are moved by hidden strings which the propagandist manipulates.” is from 1929. 1929!

The problem this time is that we had propaganda on steroids. Because of the amount of data Cambridge Analytica had, and the ability to quickly analyse it, they could provide the most targeted and efficient advertisements. If you think about it, this is the dream of *every* advertisement agency. Now, does that mean we should forbid propaganda? Well, I lean towards yes, but I also admit that there is a thing such as good propaganda [2]. So we should not discard it as an activity altogether. One could say propaganda/advertisement [3] should not be biased, but isn’t that an inherent characteristic of it? When people are trying to sell something (a product, an idea, an image), they kind of have to be biased towards that thing.

So what is it about the Cambridge Analytica case that bothered so many people (myself included)? I have had this lingering feeling that it crossed a line. But which line? After thinking a lot about it, I suspect this line is ethics.
First of all, these people were using exaggerated messages, sometimes blatant lies, to attack the opposition. Attacking the opposition is a low blow of desperate people, specially in politics [4]. This is a dirty move which I find disgusting. You want to advertise yourself? Fine. Show off your advantages, don’t hit the adversary. That makes me very angry.
Secondly, this was targeted to influence people on important decisions, which ideally should be taken with the minimum amount of bias. The only way people are going to start to think critically, is if they have to in order to form an opinion. If they are bombarded with information from only one side, it is brainwashing. I can see why a politician or government would think this is a good thing (“I know what is best for the people, I am just making them realize faster”). However, if you stop to really think about it, this is a disservice for the society as a whole. It simply creates citizens that follow the herd, and are lazy to think for themselves [5].
At this point, one possible solution would be to forbid advertisement related to elections and any issue that would affect society as a whole. Honestly, I think this would be a good thing, and it could solve many problems we face today in a democratic process (not only the one presented here). But I need to think more about this one.

Ultimately, this whole situation is much more complicated than portrayed in “The Great Hack”. There are fundamental problems that we have been facing for many years now, it is simply exacerbated by the effectiveness of a new method. The issue, as I see, is not the method in itself, but the fundamental problem of advertising/propaganda. Where do we draw the line of good/acceptable propaganda, and unacceptable one? Who should be responsible for regulating this? As usual, there is a whole area of study about persuasion, advertisement, etc. As usual, we will only pay attention and try to solve it when things explode and it becomes obvious that this is the problem. We never learn…

[1] And I hate Facebook…
[2] Government funded campaigns for vaccination, anti-tobacco, more exercises, etc.
[3] I am using the two words interchangeably, since it is quite debatable what distinguishes one from the other. In Portuguese, for example, there is only one word to describe what would be two different things for an English speaking person.
[4] 11 years ago, this was an issue in the election of a mayor where I come from. I wrote about here (in Portuguese), after hearing an admission that, still today, makes me furious.
[5] For example, do you think I just thought about all of these things at once? It took me weeks thinking about the documentary, discussing it with other people, and researching, until I formed this opinion (which could be changed in light of new information).

About handmaids

I was visiting a friend recently and she happened to have a copy of “The Handmaid’s Tale” at her place. I had heard about this book before, and my friend also recommended it, so I decided to read. I finished it surprisingly quickly… Not only because I needed to give the book back 🙂

If you have not read the book, don’t read this post further. Go read it and make your own opinion about it.

The language is easy and the story kept me interested. Not in a Sherlock Holmes kind of way, where we are eager to find out who committed the crime, but in an Alice in Wonderland way, where we just appreciate the surreality of the situation. Except that it is not such a nice and fantastic world, but a scary post-apocalyptic one.

The story takes place in a near-future totalitarian state, which is (apparently) at war with neighbors, and follows a nuclear disaster that left a lot of the land unusable. As with any novel about a totalitarian state (such as 1984 and Brave New World), the lack of individual freedom is the focus here: everyone has their role in society pre-assigned, and no deviation is possible, specially questioning or going against the status quo. Different from the aforementioned books, this one focuses in particular on the role of women in this dystopian society. There are three “classes” of women: the wives, the child-bearing, and the cooks. Men should have at least one of each class (with some exceptions). The story is told from the point of view of one of the child-bearing ones. She contrasts her previous life (not too different from the lives we lead today) with the current one, the training she had to go through, and the struggles to maintain her sanity. She “belongs” to a “commander”, a seemingly high-ranking official, who, at some point, breaks the protocol and starts to have a more personal relationship with the protagonist. This is hardly the main point of the story, but I found one of these interactions particularly interesting. In the excerpt below, the commander attempts to justify the new imposed system on women:

We’ve given them more than we’ve taken away, said the Commander. Think of the trouble they had before. Don’t you remember the singles’ bars, the indignity of high school blind dates? The meat market. Don’t you remember the terrible gap between the ones who could get a man easily and the ones who couldn’t? Some of them were desperate, they starved themselves thin or pumped their breasts full of silicone, had their noses cut off. Think of the human misery.

He waved a hand at his stacks of old magazines. They were always complaining. Problems this, problems that. Remember the ads in the Personal columns, Bright attractive woman, thirty-five… This way they all get a man, nobody’s left out. And then if they did marry, they could be left with a kid, two kids, the husband might just get fed up and take off, disappear, they’d have to go on welfare. Or else he’d stay around and beat them up. Or if they had a job, the children in daycare or left with some brutal ignorant woman, and they’d have to pay for that themselves, out of their wretched little paychecks. Money was the only measure of worth, for everyone, they got no respect as mothers. No wonder they were giving up on the whole business. This way they’re protected, they can fulfill their biological destinies in peace. With full support and encouragement. Now, tell me. You’re an intelligent person, I like to hear what you think. What did we overlook?

Than Handmaid’s Tale (Chapter 34)

Indeed, when put this way, it is almost tempting. What a relief it would be to become suddenly free of all these struggles. Not worrying about looking pretty, having the “right” body, face and behavior… Not worrying about finding someone to start a family with, if it will work out or not, if you would be able to raise your kids properly. Rationally speaking, the system guarantees all basic human needs, for all humans. So we see how this would make sense in the head of very pragmatic people.

But very important things were overlooked.

The main character replies: “love”. To which the commander rightfully argues that love might just be something fabricated and imposed on us, as something we *should* feel and how marriages and families work. He points out the fact that arranged marriages were common, and work out just as well.

But in both situations there is a more fundamental principle which is overlooked: freedom. Whether you choose to get married by love, or because your family has found you a suitable partner, the important part is that you *choose*. You choose your partner, you choose the clothes you wear, whether to use make up, have plastic surgery, go to the gym or on a diet. You choose to go out on a date, or ask someone out. You choose to stay married, or to get a divorce.

Or better, you have the impression that you choose.

This situation has got me thinking about the difference between things we choose, and things we think we choose. Unless you live alone in an island isolated from society (in which case you would not be reading this), there are certain expectations about you. This may come from your upbringing, your peers, your friends, and even yourself. Many times we simply internalize these expectations, and live up to them without ever realizing it. Here is a silly example of how this can come about. I recently reorganized my wardrobe and realized I have a disproportionate amount of pink tops. It is by far the most frequent color. Now, do I like pink more than the other colors in particular? Not really… As a girl, I am of course _supposed_ to like pink, and this is how I suspect these tops came about. Some were gifts, admittedly, but maybe half I bought them myself. Since then, I have been more aware of my behavior when I can choose between different colors of the same item. I noticed that my instinct is to invariably go towards pink/purple. Is this because, deep down, I just really like pink, or is it because I was raised always having a lot of pink stuff? I strongly suspect it is the latter…

My feeling is that many people (including myself) make choices according to what is expected of them, and not according to our true selves. These can be as simple as the color of clothes, or as complicated as your career, relationships, values, religion… The problem is that, if we are not true to ourselves, we end up with clothes we don’t particularly enjoy wearing, or worse. Recognizing what is you and what is imposed on you is not an easy task, but it is one worthwhile spending some time on, as this means a lighter and more authentic life.

Facebook and Banks

Just read this article: Facebook in talks with banks to expand customer service

First of all, banks do not need facebook to help them improve customer service. Anyone who has ever interacted with a bank can give a handful of suggestions that would be useful and not involve a social network or another corporation getting access to customer data. I know I did my share of filling in “feedback forms”, but these seem to go to a black hole. Instead, banks would rather collaborate with the company that has been the center of a big privacy scandal for the last year. What could go wrong? ¬¬

Second, any decent bank has a chat service for customers, usually in the bank’s website. If American banks do not have that, it is because they are in the stone age of banks. Yes, they are.

Finally, facebook may have access to the account information of some users but will not use that for “advertisement or anything”. Sure, sure…

About the world

When I was finishing my masters and deciding where to go for a PhD, I did what every student in my position would do: ask around for advice. I talked to some of my professors that did do a PhD to find out about their experiences, where they went and so on. Being a theory oriented person, I could see more attractive opportunities in Europe other than the US, and the programs looked very different (from the duration, style, tuition, etc.). When confronted with these options, I got almost unanimously the same argument:

The quality of education in the US will be better, it is a longer phd but you will leave with more opportunities and more knowledge. It will be expensive, there will be sleepless nights, you’ll have no vacations for a long time and will kill yourself to work, but it is worth it. In Europe things are much more relaxed and you will do a lot of tourism. Sure you’ll end with a PhD, but much less worthy.

I found that somehow strange… This was not too great of a case for the US, nevertheless they wanted me to go and sacrifice some years of my life for a title. Suffice to say that I did not apply for any positions in the US… In the end, I got a position in Vienna, Austria, and that’s where I went to.

Looking back, having finished a PhD in Europe and understanding better how the American programs work, I sort of see their point. I am sure you see it as well, so I will not go over that. My intention here is to say what they have not told me (maybe because most or all of them had got a PhD from an American university). Given the choice, I would *never* exchange the years I spent in Vienna and Paris for a PhD from an ivy-league school in the US. Here’s why.

I moved to Vienna alone. It was the first time I was living outside my parents’ house and I started big: other side of the world in a country whose language I did not speak. I not only had to learn how to manage my own life, but how to manage my life in a society completely different from the one I was used to. And do a PhD on my spare time. In trying to adapt, I started looking at life differently. Suddenly answers like “that’s the way things are” or “it’s just how it works” stopped making sense because here I was at a place where things were not like that and, guess what? Everything still works! (Even better sometimes…) The opportunity to travel a lot (Europe is really very small… and a bunch of different countries are just a 3-hour flight away) has contributed to that feeling. Everywhere there was something curious, something different, a new unsaid rule that everyone followed. And as we try to fit in, we test different behaviors on ourselves, and realize that many “defaults” we have can be changed to something that works better, or to something that is more “you”. It is interesting the moment you feel more at home at a place that is completely different from the one where you were born, simply because that is more in line with your values. I feel like those years were a deconstruction and reconstruction of myself, and I feel much more comfortable in my skin today than I did 6 years ago. Hopefully this will only get better with time 🙂

Sure I did learn a lot scientifically as well, and I did get a PhD, and a job. My professors might think that I got lucky. (I think so too). But even if I hadn’t got a position, and was unemployed in Vienna today, still I would not change a thing. I am a resourceful person and I could get a job eventually, even outside academia. What I have learned and how much I have grown during this experience is beyond any career-oriented measurement of success.

You might argue that the same would happen if I had moved to the US, but I don’t think so. We know too much about them. We get their music, movies, series, news, culture… From what I know, life would not be so much different from the life I had before. Also, I have lived in the US long ago. Back then, I did not realize all the nuances and particularities I noticed last semester, when I was living there for a few months again. Since we know so much, it is a hard place to feel like an outsider. Maybe it will be more comfortable, but less eye-opening.

What I want to show now, specially now, is that going to the US does not have to be the ultimate dream or the best/only choice. The world is a big place, and great opportunities are available everywhere. We just need to remember that opportunities should encompass employment *and* life as well.

About obesity

I am taking the opportunity of being at CMU for a semester and attending a course on behavioral economics and public policy. Behavioral economics is a topic that caught my attention a while ago and it’s been interesting to see it under the lens of public policy. The course is quite American-centered, and being a non-American (or “alien”, as the government likes to call me) makes it only more interesting. I am trying to understand what is the mindset, what is the “normal” around here, and I am still in awe every now and then. It’s a good state to be in. But anyway…

Today in class the subject of obesity was briefly mentioned. It is seen as a public health problem, and we were studying ways (read, public policies) to motivate people to loose weight. But that’s treating the symptom, not the cause. I like to treat causes, seems more effective. So, for the reasons why obesity is a problem, it was mentioned: decrease in food prices (specially unhealthy food), lack of time (arguably not true, we just suck at time management), sedentary lives, working parents and larger portions (why America? why??). We might add dining out and drinking soda like crazy to that list, as discussed here. Fair enough. These all look like reasonable reasons for a less healthy diet and consequent increase on obesity. Then I had an epiphany: those reasons are not America-exclusive. People are more stressed everywhere, both parents are working everywhere, sedentary lives are everywhere, cheap fast food and soda is available everywhere. So what creates this enormous demand for big portions of deep fried chicken in America specifically? [1]

Unfortunately I do not have an answer for that. What I know is that the unhealthy eating seems to be an acceptable thing. I never saw so many ads for food as I see it on TV here. Really. If you are ever in the US and have a chance to watch some TV, do it. Even for half an hour. It is an interesting experience (not only because of the food ads). I have the feeling that one in every three ads is about food. And not healthy food: fried chicken, giant burgers, 2 feet (~60 cms) pizza, a burrito stuffed with three types of different melted cheese, pancakes made with buttery croissant dough, chocolate cookies filled with more chocolate and marshmallows… you name it. Ironically, another third fraction of the commercials are dedicated to medicaments. As if it is not enough to bombard people with ads for greasy and processed food, they go to the next level and actually *scorn* healthy eating. Just take a look at this or that. Americans, do you have any idea how absurd it is to have an ad like that? This should have never ever been approved!! I would boycott Domino’s if I ever ate there.

I am not sure if these ads can be counted as a cause or effect of obesity, it is a chicken-and-egg problem. What I know is that regulating such things properly will do no harm, but only good [2]. It’s a no-brainer. On top of motivating people to loose weight, how about cutting on the temptation for eating in the first place?

[1] As a side note, Brazil is also not the healthiest country around. And I lived there, and even so I cannot explain what happens… Seems to be a cultural thing (that needs to change!).

[2] Regulation is needed when people lack the common sense and allow such horrendous ads. Unfortunately, those that make regulations are also people.
