Have you read the lesswrong.com rationality blog yet?

A couple of months ago I came across an amazing blog about rationality: lesswrong.com Its

main author is Eliezer Yudkowsky , an artificial intelligence scientist and co-founder of the Machine Intelligence Research Institute . It was he who wrote one of the most important sections of the blog, the so-called Core sequences - a series of blog entries that tells how to learn to think rationally.

The blog covers many important topics, from the history of science and the Bayesian derivation to quantum mechanics and cognitive psychology .

Some interesting facts to attract attention:

• Alchemists of the 18th century believed that fire is nothing but a consequence of the existence of a certain “Phlogiston”. With it, they could explain anything. "Why does a tree turn into ashes?" "What is this orange thing, which is also called fire?" "Why does the fire go out in an airtight container?" The answer was one - Phlogiston .
• In 1975, scientists conducted an experiment: They chose a certain historical event (the conflict between the British and the Gurks in 1814) that not a single person from the group of subjects heard about, and a set of possible outcomes: the victory of the British, the victory of the Gurks, a draw and a peace treaty, a draw and lack of a peace treaty. The subjects were divided into five groups, four of them reported the event and one of the results (saying that he really was), and the fifth only about the event itself, but they did not say how the case ended. Then they were asked to calculate the probability of each of the possible outcomes. It turned out that each of the groups assigned a significantly greater likelihood to the option that they called the right one. This cognitive bias is called Hindsight Bias .
• There is a theory that time is an excess parameter in all equations. There is only cause and effect. The fundamental equations in it are described without its use. Timeless physics

After I started reading this blog, my views on the world have changed a lot; it seems to me for the better. I recommend the same to you, in the name of science!

PS Also, Elizer writes a Harry Potter fanfiction - Harry Potter and the Methods of Rationality , which talks about the same things in a lighter form.

UPD: In the comments they suggest that both the blog and the fix are translated into Russian: lesswrong.ru/w/Main_Page and hpmor.ru, respectively.
