What research has been done on the altruistic impact of the usual good actions?

Part of my interest behind this question is that recently I've been noticing the subtle (but also not so subtle) ways our choices affect the people and the social fabric around us. Also, listening to Jordan Peterson highlight historical cases where the moral fabric of society fails (e.g. Nazi Germany and Soviet Union). It makes me think there's a lot of under-appreciated value in being a morally upright person. Some of the value is in directly impacting the people around you, but the majority is in signaling that "this is the kind of society we live in."

Coordination as a Scarce Resource

Love your posts! I’d recommend publishing them at a slower pace so people get a chance to see and read them. It’s also a bit confusing on LW when several posts are published on the same day, and you can’t tell which one is first in the series (just from the front page).

Is it worthwhile to save the cord blood and tissue?

One source I looked at was:

Some highlights:

  • There are three public cord blood banks in CA, but non in the bay area. So donating might be hard if that's where you're delivering.
  • The expected cost of cryo preserving is a bit under $2,000 upfront and $150 / yr.
  • It costs about $30,000 to obtain a cord blood collection from a public bank, and that cost is charged to the patient’s health insurance.
  • Looks like the stem cells could be used by the family members too. (Assuming it's a match, I'm guessing?). But actually the child might not be able to use them. (Is it only while they are a child?)
  • The main advantage of cord blood is that it does not have to be exactly matched to the patient like transplants from an adult donor.
  • In the United States, about 80% of cord blood donations are discarded.
  • In the United States, the net probability that a child will need any type of stem cell transplant by age 20 is 3 in 5,000 or .06%.

Can you expand on “ AI/ML capabilities research in finance” or shoot me a PM?

human psycholinguists: a critical appraisal

I’m definitely not an expert, but it does sound like a few people moved the goalposts. It sounds very similar to the "AI can't play chess" argument switching to "well, it's not really playing chess, it's just following rules" and then to *quietly mumbling something about it not having the True representation of chess*.

So, I agree with the core point. GPT-2 is writing! And it's writing pretty damn well. Whatever is left has more to do with the general cognition skill than writing.

What spiritual experiences have you had?

Great question! I will just say that I had such an experience, but don’t know how to share it in a way that feels adequate for me.

Get a Life

I think you can lead a healthy and happy life playing tennis most of your time, while avoiding the (incorrect and unhealthy, in my opinion) belief that “getting a life is finding a singular passion and pursuing it to the end”. It seems to me like a motivated reasoning used to defend what the person is doing. However the rest of the post is closer to the real truth: “I enjoy playing and teaching tennis and I find meaning in it.”

Also I think the singular/plural purpose divide is pretty smooth with plenty of people on both sides. I’ve met lots of people who say that to live your life you basically need to specialize like crazy.

My invitation to the author would be to write a similar essay to steel man the other side.

Bayesian examination

Wow, this seems huge to me! Great find! I’m not in the business of constructing tests, but if I ever do any home schooling with my children, I’ll definitely try this method.

If giving unsolicited feedback was a social norm, what feedback would you often give?

Your decision / advice is rooted in anxiety / fear. This is much more about you than about the thing you’re talking about.

Laws of John Wick

This post convinced me to watch the movies. Was not disappointed: great world building indeed.
