How heritable are human traits like personality, height, mental health, physical health, education, religiosity, and conservatism? (h^2 estimates)

June 12, 2024
Here's my attempt to compile the heritabilities (in the narrow sense of h^2) for many different interesting human traits. Before you read this, however, I recommend you read our piece on the Missing Heritability Problem which provides important context for interpreting this information. We'll first look at estimated heritabilities from five categories: body, mental health, physical heal...

Are happiness and well-being the only things that people value?

Are happiness and well-being the only things that people value?
June 5, 2024
The most common kind of critiques I get of my theory of human intrinsic values are: 1) "But I only care about well-being (in the sense of happiness, pleasure, or lack of suffering) - that's my ONLY intrinsic value." 2) "People may THINK they value other things, but everything that matters bottoms out in well-being." Here's my response: First of all, I want to say that I really app...

How can big problems get solved?

How can big problems get solved?
May 5, 2024
I think that big problems in the world (like chronic homelessness, loneliness, depression, poverty, underrepresentation of groups, risks from A.I., global warming, etc.) are ridiculously complex - way more complex than the narratives about them suggest. The only approach I know of that I think has a meaningful shot to help solve such huge problems, which you might call “Scientific Entrepreneur...

How to spot real expertise

How to spot real expertise
April 23, 2024
Thanks go to Travis (from the Clearer Thinking team) for coauthoring this with me. This is a cross-post from Clearer Thinking. How can you tell who is a valid expert, and who is full of B.S.? On almost any topic of importance you can find a mix of valid experts (who are giving you reliable information) and false but confident-seeming "experts" (who are giving you misinformation). To make m...

There are three different motivations for belief, and it's important to distinguish between them.  1) Belief because you think something's true. For instance, you may think that the evidence supports the idea that you will eventually find love, or you may feel convinced by logical arguments you've heard in favor of god's existence. 2) Belief because you think it's useful to believe....

The benefits and soul-crushing downsides of A.I. progress

April 11, 2024
There are many benefits to A.I., such as being able to generate beautiful art, inspiring music, captivating writing, and mesmerizing videos. It democratizes creation (people can now create what’s in their minds), lowers costs (replacing human labor with algorithms), and enables hyper-personalization (works can be made just for you). The benefits are big and important. But there is also somethi...

In memory of Daniel Kahneman, who accelerated our understanding of the mind

In memory of Daniel Kahneman, who accelerated our understanding of the mind
March 27, 2024
I'm not a person who has idols, but Daniel Kahneman came about as close as it gets for me. It is not an exaggeration to say that he revolutionized our understanding of the mind. Among many other concepts, Kahneman and his collaborators came up with the ideas of: Anchoring (where an irrelevant number can influence our judgments) Prospect theory (a theory of how we make judgments when the...

March 15, 2024
Here are some of the most useful simple methods I've adopted for improving my connection with others (though I still have room for improvement): 1) When you like someone, greet them warmly, demonstrating with your face and body language that you like them. 2) Try your best to channel "interested attention" in conversations - where you give the other person your total focus while paying ...
