Founder of Farnam Street (fs.blog) and host of The Knowledge Project podcast. Writes and curates on decision-making, mental models and rational thinking.
In my conversation with @bgurley he talked about this too. He called it bedrock. When he first learned investing, he read 'Peter Lynch, One Up on Wall Street. A Random Walk Down Wall Street. All the Buffett letters, Ben Graham, and Howard Marks.' "In order to be great, you want to learn all the bedrock principles you possibly can but then, once you know those have the independence of thought and the confidence to innovate on top of those principles." Studying the history and knowing the pioneers is the closest thing to a cheat code you're gonna get. Quoting @TKPPodcast "We have the only industry in computing that doesn't even know its heroes... no one knows Alan Kay and Dennis Ritchie and Ken Thompson. This matters, I think, because we discard great lessons and have to rediscover them over and over again." Related

By recognizing the higher-level consequences nature optimizes for, I've come to see that people who overweigh the first-order consequences of their decisions and ignore the effects of second- and subsequent-order consequences rarely reach their goals. This is because first-order consequences often have opposite desirabilities from second-order consequences, resulting in big mistakes in decision making. #principleoftheday Related

Lots of games can be made by just starting to mess around and seeing what works. You get a guy on screen, have him jump on stuff, or shoot stuff.

I can tell you with complete certainty the twin prime conjecture is true. The random model gives overwhelming odds it is true, I just can't prove it.

And the trick here is not to act too much on the feedback that the very disappointed people are giving you because they already love your product. Also, not to act at all really on the feedback that the not disappointed people are giving you because they're so far from loving your product that they are essentially a lost cause. but to focus on the segment of the somewhat disappointed people.

And this is important, so yes, you should expect legs or jointed sticks, how many joints they're going to be? Anybody's guess. Do you expect humanoids, things with a sensing apparatus on top of a shoulder with two arms and two legs? That's probably a pretty random set of occurrences that led to that.

From one piece
Sara Walker: Physics of Life, Time, Complexity, and Aliens | Lex Fridman Podcast #433
2 beliefs, in the piece's order there
Their words
Physics hardly even acknowledges that the universe is random at its base. We like to think we live in a deterministic universe and everything’s deterministic. But I think that’s probably an artifact of the way that we’ve written down laws of physics since Newton invented modern physics and his conception of motion and gravity, which he formulated laws that had initial conditions and fixed dynamical laws.

It’s the fact that you’re a deterministic structure living in a random background. And also, all of that selection bundled in you allows you to select on possible futures. So that’s where your will comes from.

Friedman’s focus on the money supply has not held up, as Samuelson suggested, but the alternative Keynesian macro models recommended by Samuelson in the same interview have not done better and they were not outperforming simple random walk models of predicting the macroeconomic future.

A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.

About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
