I was raised in a religious household and took it very seriously. At the same time, I always enjoyed skepticism and debunking, because I was always entertained by such things. But when it came to philosophy I was completely full of it. I got away with it by living in an area where I only encountered other Christians, not many atheists. When I did actually encounter some atheists, I would do some hand-waving about how there was something Deep and Intellectual about Christian apologetics that they were missing.

I dated someone who was extremely, well, hippie. Completely non-judgemental about even the most absurd hypotheses. I really hated that kind of attitude--where was her intellectual curiosity? So I got more into specific skeptic arguments. I fell in love with James Randi and watched almost every video of him that existed on Youtube at the time. But I waited to apply any of the lessons to the Big Question. Christianity was a huge part of my life; my entire family is still very seriously Christian, and a huge chunk of my social network used to be.

I started reading Overcoming Bias because, hey, Mason econ student, why wouldn't I read another great blog? There are several lessons on ... (read more)

When I was in second grade, about seven years old, it was my turn to do a show-and-tell project, so I decided to bring a game I'd learned from a book that purported to be about geometry or math or something but seemed to mostly involve silly arguments between a talking turtle and a greek athlete. I assumed my fellow students would enjoy it, since the rules were relatively few and simple (compared to, say, spelling homework) and the victory conditions utterly unambiguous (compared to the bitter disputes of scoring in various playground activities). It seemed to relate to what we were learning, so the teacher might even approve further study.

I could hardly have been more wrong.

The rest of the class just stared blankly, and even the teacher didn't seem to get it. "But," she said, "You've got 'mu' right there at the start. Why don't you just cross out the rest?" I protested that such a move would be against the rules, but was unable to convey the underlying significance before show-and-tell time was determined to be over.

The book was Goedel, Escher, Bach by Douglas Hofstader. I figured that if the teacher couldn't begin make sense of it, none of the other kids were... (read more)

I became an atheist fairly early, but it took me longer to realize there was no Santa Claus. The idea didn't make sense, but the presents appeared under the tree, and my parents denied being responsible, so clearly they'd gotten there somehow. I concluded that I just didn't understand some important part of how the world worked.

One year, we'd just moved into a new house. For the first time, we had a real fireplace, made of brick. I excitedly spoke of how this would make visiting much easier on Santa, but wondered how he could make it down a chimney at all, and began making plans to string a net of dental floss across the opening in an attempt to see how Santa dealt with the obstacle.

I had been leaning on the brickwork, looking up the flue, as I said these things, and as I turned around I intercepted a look my parents were giving each other. Translated into English, it might have said something like "Isn't this precious?"

In that moment, I intuited that there was no Santa Claus, and that my parents had been lying to me because they thought my belief was cute.

I had already learned that not everyone was my friend. I already knew that some people who weren't my friends a... (read more)

Christianity drove me to rationalism. I went to a Catholic college where we had to take 2 semesters of theology and 3 semesters of philosophy.

We studied Aquinas for weeks. Knowing that Aquinas was generally regarded as the smartest person in the Middle Ages, I was stunned by the stupidity of his arguments. Aquinas could not have been stupid. Therefore, social pressure was capable of warping the minds of the smartest people on the planet for a thousand years. Therefore, it could be warping my mind right now.

Another thing we did was to study a parallel edition of the gospels. That means that it has one column each for Matthew, Mark, Luke, and John. Laying them out side-by-side, I saw many places where Matthew, Mark, and Luke had identical sentences. They couldn't have come up with the same grammar and word choice independently. At least 2 of them had copied from someone else. I had studied the Bible all my life, and was surrounded by hundreds of people who also studied the Bible regularly. Some of them had read it every day for decades. And none of them had ever noticed this; or if they did, they didn't mention it. (It is universally known to Biblical scholars; but most ...

It was akrasia, Dostoyevsky, and the sacrament of confession that turned me into a rationalist. Seriously.

I became very religious as a teenager (for social reasons, as I'd later realize), and drifted more and more traditional and conservative (since I could see that liberal Christianity is generally logically incoherent). This drew me into theology (thus philosophy), so that I'd been exposed in college to all the arguments I needed to reject Christianity; I just refused to apply them, generally taking them one at a time and playing One Argument Against an Army.

What changed in grad school had to do with the internalization of the virtue of honesty. Because I had to confess my sins frequently, I became more and more aware of my rationalizations and self-deception (in areas of discipline and akrasia, not of course rationality). I took to heart what Dostoyevsky wrote in "The Brothers Karamazov":

Above all, do not lie to yourself. A man who lies to himself and listens to his own lie comes to a point where he does not discern any truth either in himself or anywhere around him, and thus falls into disrespect towards himself and others.

Before long, though, the practice of l... (read more)

The distant: I am diagnosed with Asperger Syndrome (an autism spectrum disorder). I was unpopular at school, I understood poorly how to fit in, but I understood well how to get smarter. I took high school completion mathematics exams in primary school, university exams in high school, and while I never bit a teacher like in HPMoR, I did punch a student one time and demand that the teachers back me up.

As I remember it, said student was talking about a "tirus" which was supposedly like a next-generation virus which would eat up your computer unless you washed your motherboard properly with soap and water. Being a nerd with some technical aptitude, I told him that he was a bullshitting liar and he was to show me what he was on about or stop it immediately. He continued, so I told him to shut up or I'd hit him. He still continued, so I punched him in the stomach, which winded him and made him shut up. The student was surprised that I had carried through my threat, the teachers were surprised that I was unapologetic, and I was surprised that the teachers (this was at a religious school) were putting a distinctly man-made and exception-deformed rule about limits to hitting over...

Hi everyone. Just to note from the beginning of this comment, I'm a bit different from the typical LW demographic, so maybe this will help shed light on another way of coming to rationalism.

I was born into a mildly Jewish agnostic household, but when I was about 4, I became strongly drawn to Christianity. I didn't know much about it, but I somehow heard about heaven and hell, and that was definitely what drew me in. I was terrified of the idea that people didn't get what they deserved, that bad things happened to good people, that when people died they were really gone forever. When I asked my mother about concern she explained that life isn't fair. But I knew that couldn't be true. Because if it was, if there was no supernatural protection against evil and death, then of course everyone would be frantically working to make it better all the time. I knew there were kind, intelligent people in the world, and they weren't doing this, so they must have a good reason, like that they didn't need to for reasons I didn't know about. I was very confused, and the idea that most people believed in heaven and hell, and it was "okay" that life wasn't fair and we were all go... (read more)

When I was 5 or 6, I wanted to be a palaeontologist. I ended up with a small collection of fossils and whatnot, as well as an awareness of both evolution and how old the Earth is. As the infallibility of the Torah was obvious, I assumed that its interpretation, which I wasn't yet old enough to learn, explained how everything could be reconciled. In any case, I had much more serious things to worry about. For instance, the boys and girls I knew showed no inclination to date or marry - therefore the human race would shortly end, unless the Moshiach came. Having tagged 'God exists, Judaism is right' as being obviously true, I simply didn't think about questioning it for a long while. As time went on, I did realise, slowly, that just because I'd decided something was correct, like inexorable human extinction, didn't make it so, and that I was not infinitely smart.

When I was 13, I had my Bar Mitzvah and was surprised that I didn't start observing the strictures of Orthodox Judaism, such as not manipulating electricity on Saturday. Now that I was responsible before God for my actions, I should have been much more compunctious, but I couldn't believe that I would be punished for such thin... (read more)

I followed the standard Questioning Religion(TM) route. When I was twelve, our family had a bit of a crisis: my dad's job looked insecure, my mother was having difficulty with her side of the family, and I was home schooled and acutely aware of the fact that this was why I had no social contact with my peers. At all. The solution, as my fundamentalist curriculum (complete with pictures of Adam and Eve in the garden of Eden with dinosaurs(!) in the science texts (!!!) ) put it, was to pray for God to magically fix it. Which of course he could do, he's omnipotent! He's God! And he loves all the little children, right?

Several weeks of ardent praying later, my twelve year old self began to smell something fishy. Coincidentally, in the mandatory Bible class (these were DVD correspondence courses), the teacher told the class, "God answers prayers with 'Yes, no, or maybe.' "

"Well, what on earth is the point of praying, then?" said my twelve year old self. I stopped praying. Coincidentally, my life drastically improved after that, so I felt that prayer hadn't altered the outcome one iota. I came to the gut conclusion that Christianity couldn't be right. Manda...

I was born in China, and moved to the US at the age of 10. My parents were both educated in Communist China and therefore atheists. I do not recall any anti-religious education in school, but do have a fairly vivid memory of watching a state-produced television program on the evils of 迷信 (superstition), which somehow left a deep impression.

After moving to the US, I remember watching Star Trek (reruns) as a teenager and admiring the Spock character. But I don't think I ever had a strong interest in learning how to be more rational, and instead just had an intellectual curiosity in topics that happen to be related to rationality, like economics, game theory, cooperation, the nature of probabilities and anthropic reasoning, the future, the Singularity, moral philosophy, etc., which led me to OvercomingBias and then LessWrong. Even now I think I'm driven more by a desire to satisfy my curiosities than to accomplish any larger goals.

I think my experience may be a counterexample to Something to Protect and Try Harder, but I don't really see how to generalize it.

Must everyone begin as not trying to be rational? I probably did too then, but I don't remember it. Trying to be correct by making your thought processes accurate seems like a pretty obvious thing to do (I assume that's what's meant by rational). I've rarely been so shocked as when I realized (at about 12 I think) that it's normal and not embarrassing in society to have opinions for 'arbitrary' reasons. I'm still kind of puzzled about what else you would think you were doing, even if you are delusional about your success. What did you folk transition here from?

I think I began as a rationalist when I read this story. (This was before I had run across anything Eliezer wrote.) I had rationalist tendencies before that, but I wasn't really trying very hard to be rational. Back then my "pet causes" (as I call them now) included things like trying to make all the software transparent and free. These were pet causes simply because I was interested in computers. But here, I had found something that was sufficiently terrible and sufficiently potentially preventable that it utterly dwarfed my pet causes.

I learned a simple lesson: If you really want the things you really want, then you need to think carefully about what those things are and how to accomplish them.

Hello, everyone. I feel that I have taken an unusually circuitous route to becoming a rationalist. I started out close to rationalism in ideaspace, went really far, and then came all of the way back. I have to begin by saying how rationalism was 'epistemically proximal' to my early beliefs. After that, I'll show how far I went. Then, I'll show how I came back.

I think it can be said that my intellectual influences have been relatively epistemically favorable. I think it all started with the film adaptation of Jurassic Park when I was a kid; I think that it made me find joy in the merely real. If dinosaurs are that awesome, and they were dead and science brought them back, then science must be awesome! Then I became interested in outer space and all of the other things that kids automatically love when they love science. When I was older, like many others, I sometimes felt the urge to write science fiction. If I remember correctly, I was researching terraforming for one story, and then I came across a Wikipedia reference to Robert Freitas' respective estimations for how long it would take biological organisms and nanotechnological machines to sequester all of the carbon dioxide in th...

Here is my long-winded origin story, with an emphasis on the importance of community.

My first exposure to a community of like-minded intelligent people was in high school math camps. The amount of motivation could almost be felt in the air. After a whole day of lectures and problem sessions, when there was finally time to chill out and play some card games, many people were still discussing the most interesting problems from the sessions, or whatever other math they had on their minds. It was a place where it was ok to care about something enough to work on it all day, and I could never match that amount of cognitive output during an ordinary day at school. Even the card games were of the more mentally challenging sort, like Mao with its ever-accumulating arbitrary rules to be guessed and kept track of. Thinking was not considered effortful.

The Canadian math camp community made my high school years a golden age of sorts. It did, however, have a narrow focus that was unsustainable on the long term. Math contest problems are neat and challenging and elegant but they are still just toys - made to be solved within an hour or two, guaranteed to have a nice solution, even if devilishly...

Eliezer asks "how did you come to rationality?" It surprises me how many people answer: "this is how I lost my religion"

Clearly you can't be rationalist, while also being religious, but there is a more to rationality than simply absence of religion..

Anyway... personally: there's no one moment, but I'm a natural born sceptic and persistently urious analyst. Perhaps rationality attracted because it seems like methodical, organised, analytical scepticism

Single biggest book: Hofstadter's G-E-B, right when it first came out. I just didn't know there could be a book like that....

The first time I explicitly saw myself as someone who cared more about rationality than the people around me was on the playground, in third grade. Like other kids my age, I was fond of playing kickball at recess. We often had arguments over whether a baserunner had been successfully tagged out.

The odd thing was that, even though most people in the group didn't like watching arguing for more than a minute or so (you could tell because people started yelling things like "Shut up" and "Just play" with big scowls on their faces), nobody could resist the temptation to take sides in the argument long enough to end the argument. Yes, people thought that it didn't much matter whether Eddie was out at second, but they also couldn't help but point out that Eddie was obviously safe/out, inevitably prompting a renewed outburst of cries that Eddie was obviously out/safe. Sometimes we argued about whose fault it was that we were arguing so much instead of playing.

I never took sides. At some level, I already cared more about my goal (having fun playing kickball) than I did about tribal politics.

The kickball thing quietly but powerfully framed the way I looked at friendships,... (read more)

I grew up in a Reconstructionist Jewish household with an Orthodox dad and an Israeli mom. I'm sure they used to think that I'd become this great Jew - I was sent to a Jewish private school, and I realise now that I was (and still am) a perfectionist, which meant I felt the need to do all the prayers and ceremonies properly. The first push towards rationality came sometime in second grade, when I asked my parents if I was adopted (long story) because I'd never heard a solid answer in either direction from them before. When they said I was and that they had... (read more)

I would never have identified as a rationalist had I missed this site. I never had a very strong commitment to the truth, as I am something of a chronic liar. I used to make deliberate attempts to try and manipulate people in ways borderline to the Dark Arts.

I did however desire to have a consistent set of philosophic rules that eventually led me into an existential crises of sorts. I was raised by a deeply conservative (in ideology, but certainly not action) father who is easily the smartest person I know personally at the moment. He was intelligent enou... (read more)

I bet my experience is pretty typical: it's just been one really long of string of oops, as far back as I can remember. I realized I was wrong, I updated. I started with nothing... no beliefs, just professions that I think I realized were transient. Slowly but surely I converged on agnostic Buddhist Epicureanism with a little Sagan, then atheist scientific liberal majoritarianism at RationalWiki with a little Dawkins, then neorationality here with Yvain and Eliezer, then hyperrationality at SIAI with a whole bunch of really strong thinkers, and now I just ...

Disclaimer: Cognitive science says that this incident probably didn't happen the way I remember it.

When I was 5 years old, my mum sent me to Sunday school because she was casually Church of England and that's what you did. It was only the second or third time I'd been and after the lesson they had us pass around a box full of sweets and told us each to take one. I remember thinking that there was something I really didn't like about this as the box was coming around so I passed it on without taking a sweet. One of the women running the group noticed and as... (read more)

I want to say that my own origin lies in having been raised Unitarian Universalist with the most amazing minister who never invoked "God" as anything more than the common good or interpersonal kindness. I want to believe that UU Sunday school attendance, or, more interesting to me even at that young age, ditching class and sticking through the "adult" section of the worship, where she would give the most awe-inspiringly inspirational sermons, would be enough to awaken any child as a rationalist. Alas, I am fairly certain I was prepared ... (read more)

Most of the math and explicit rationality came later, after I learned to program, but my first step down this path was probably when I was around six. I was suspicious of the whole idea of the tooth fairy, so one night after losing a tooth I did a little experiment: I put it under my pillow without telling anyone. The next morning, I showed my parents, and they actually came clean (obviously they couldn't keep things going with santa claus or anything else like that). I think I still kept a vague sort of religion for a few years after that, though.

When I was a little kid we would take car trips to visit my grandparents, and my father would borrow books on tape from the library. He borrowed Asimov's "I, Robot", which if you haven't read it is basically "House, M.D." except that instead of people you have robots and instead of Dr. House you have a pair of underpaid robot repairmen. It didn't introduce any concepts of rationality directly, but in the book the heroes won by figuring things out, rather than by being strong or passionate or morally correct. It made figuring things out cool, and it turns out that if you want to figure things out, you use rationality.

I can’t remember a time when I was not very much concerned with rationality. I think my father (a neuroscientist) encouraged those kinds of ideas from the time I was learning to speak my first few words, always reasoning with me, nudging me to think straight. I developed a deep interest in science from about the age of five and there was never any competition from other ways of viewing the world. Things like game theory and heuristics and biases came to me much later (when studying economics), and although I was excited about it, it didn’t really rock my w... (read more)

I spent the first six years of my life in Israel, and the rest in France. Now, my immediate family wasn't really religious, but cultural osmosis did lead me to believe in the better-known Old Testament stories - a vague belief in God, as others might believe in Santa Claus (I also believed in the Tooth Fairy. And that she looked like Gonzo in a skirt. Muppet Babies may have been to blame).

Around age 8-10, I became enamored with science, which became central to my worldview. Now, one of the books I owned around then was a children's animal encyclopedia, and... (read more)

I began my journey to becoming a rationalist at the age of six. This was the time when I first began to read fantasy. There are other contributing factors such as my parents inclination to free thinking. In following my dad's work we moved considerably, introducing me to many ways of thinking and setting me up for a bookish, introverted perspective (friends are much more difficult to stuff into boxes and ship to Africa.)

Choosing to read fantasy was the first conscious choice I made that influenced my development towards rationalism. I've always found the m... (read more)

My story isn't very interesting, sadly.

As a very young child*, at Sunday School I was told that prayer was supposed to be a conversation and not a monologue by just me. After a year or two with no one talking back and no other religious experiences to speak of, I began to wonder if there really was someone at the other end.

A year or two later still, I decided that if there was, I would have heard something by now, and became a full-blown atheist. (Although to avoid jeopardizing Christmas and Communion and Easter, and because it'd probably annoy my family, ... (read more)

I can't really say what defining moments could be considered my rationalist origin story. However, I can speak of my brief foray into the world of woo, and how the first virtue both endangered me and gave me a savings throw.

In those days, I also felt like a budding renaissance ... (read more)
