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 matters even more confusing, sometimes the fake experts even have very impressive credentials, and ev...

Human universals: 6 remarkable things I think are true of nearly all adults

October 20, 2023

Some remarkable things I suspect are true of nearly all adults: 1) We each hold some beliefs that are almost totally non-responsive to evidence involving some combination of our identity (who we are), our group, the nature of reality (e.g., God), or the nature of what’s good. Examples: • Many have an unshakable belief that they are good even as they harm the world (or believe they’re insufficient even though they’re altruistic and productive) • Most have an unshakable belief that t...

False Beliefs Held by Intellectual Giants

July 15, 2023

Even many of the smartest people that have ever lived convinced themselves of false things (just like the rest of us). Here are some fun and wild examples: (1) Linus Pauling won TWO Nobel prizes - one in peace and one in chemistry. Unfortunately, he eventually became obsessed with and widely promoted the false (and sometimes still repeated) idea that high-dose vitamin C cures many diseases, including HIV and snakebites. (2) Isaac Newton, who co-invented calculus and discovered t...

Did That Treatment Actually Help You?

April 15, 2023

A mistake we all make sometimes is attributing an improvement to whatever we've tried recently. For instance, we may get medicine from a doctor (or go to an acupuncturist) and feel better, so we conclude it worked. But did it actually work, or was it just chance? Here's a trick to help you decide: What matters (evidence-wise) is how likely that level of improvement would have been in that time period if the treatment works relative to how likely that improvement would have been if the treatm...

Soldier Altruists vs. Scout Altruists

April 23, 2021

There is an important division between people who want to improve the world that few seem to be aware of. Inspired by Julia Galef's new book (The Scout Mindset), I'll call this division: Soldier Altruists vs. Scout Altruists. 1. Soldier Altruists think it's obvious how to improve the world and that we just need to execute those obvious steps. They see the barriers to a better world as: (i) not enough people taking action (e.g., due to ignorance, selfishness, or propaganda), and ...
