Bayes' rule: A powerful thinking paradigm | Julia Galef

Показать описание
Think via Bayes’ rule to become more rational and less brainwashed.

Bayes’ Rule is a powerful way to think about evidence, says Julia Galef, co-founder of the Center for Applied Rationality.

Most of us have preexisting beliefs that we stick to firmly, unless we have a breakthrough—that is, we encounter evidence that is so overwhelmingly inconsistent with our beliefs that it forces us to change our minds and adopt a new theory. But even then, we don’t always change our minds.

Growing aware of Bayes’ rule produces powerful, fundamental changes to your thinking. Bayesian thinkers view their beliefs as grayscale; they’re not black and white. You can have “levels of confidence” in ideas that change over time, rather than wholesale subscriptions to ideas that never change.

Fortunately YouTube recommended a video of Julia explaining Bayes’ rules directly beneath this one.

Bayesian thinking is also a great mindset tool for counterfactual reasoning and critical thinking. I encountered the theorem almost 30 years ago, and it changed my life completely. Who I am today it's also because of that.

I'm sure she spoke much longer than the final edit. My guess is that the editor didn't understand and so left out key parts of the presentation.

I just finished reading, "The Scout Mindset" two days ago. I remember taking a class Math 505: Introduction To Probability at the U. of Utah in the summer of 1980. We spent a lot of time studying Bayes Rule and its implications but it wasn't until about 12 years after that, that I discovered how controversial it is. Are you working n another book? Here's a potential title:

How to Win Every Argument by Ignoring Facts: A Masterclass in Stubbornness

I think she is proposing to adopt a way of thinking that your existing beliefs may be wrong. That way you will not look at new information through the lens of your existing beliefs but rather for what it is.

If anyone else than me is wondering, his name is Thomas Bayes and the rule is a statistical one.

Either I completely missed the point of this video or there wasn't one.

Is Bayes’ Rule sufficient for authorities to refuse to examine records available to them that would resolve the claimant’s statement?

Think, ‘He couldn’t possibly be a pedophile, he’s a Catholic Priest’, which put an end to the hopes of many for justice and to their belief in God.

I like the sentiment, just don't like the 'provably the best way' (1:10)... because no, it isn't proven. we've just seen a lot of data that it is effective. to say it is 'provably the BEST' is to literally disregard the premise behind it.

I still don't understand why you erasing my latest comments? I still haven't understand how you did this to me...I'm not hurt but I'm angered

What qualifies THIS entertainer (Julia Galef) to decide what is "rational" or "intelligent" or not? Sorry, but being an entertainer and being given free media platform does NOT qualify her as intelligent or rational. Also, show us how to get governments to overcome sunk cost fallacies. Then people will listen to you & take you seriously. Until then, no.
