In reply to: Scott Alexander’s Learning To Love Scientific Consensus. Actually, I have planned (in my mind) a somewhat longer post on my take on the ‘correct contrarian cluster’, or how to make up your mind of what to believe on controversial topics. But I certainly don’t have time to write that now, so instead […]

This post is unusually blunt because the topic concerns some rather serious criticism leveled against me. This necessitates replying with some facts that I’ve used for self-assessment purposes. In case you missed it, my post the mental and behavioral problems of kids with parents from different races generated some furor. I replied to the first […]

Being annoyed by some of the usual qualitative drivel masquerading as science (see almost any tweet by @RealPeerReview), I was moved to make a nice background/poster. en.wikiquote.org/wiki/William_Thomson A slide from some anthropologist said of Galton that he “Worshipped at the alter of quantification”. That’s a nice way to put it!

This book is written by one of the persons behind Skeptical Science, a website debunking pseudoscience in the area of climatology and global warning, very much like Talk Origins debunks evolution related pseudoscience. The book itself has more of a meta style and does not cover all arguments put forward by climate contrarians. After all, […]

Quoted from Textbook of Human Reproductive Genetics, chapter 13: PGD within the“autonomy model” According to what may be called the “autonomy model,” prospective parents are free to use PGD in order to select embryos on the basis of any characteristic they prefer, whether health related or not. Opponents argue that selecting for non-medical characteristics violates […]

Disclaimer: Some not too structured thoughts. It’s commonly said that correlation does not imply causation. That is true (see Gwern’s analysis), but does causation imply correlation? Specifically, if “→” means causes and “~~” means correlates with, does X→Y imply X~~Y? It may seem obvious that the answer is yes, but it is not so clear. […]

Title says it all. Apparently, some think this is not the case, but it is a straightforward application of Bayes’ theorem. When I first learned of Bayes’ theorem years ago, I thought of this point. Back then I also believed that stereotypes are irrelevant when one has individualized information. Alas, it is incorrect. Neven Sesardic […]

I had the impression that, since recognition of [problem] dates back at least to [person from a long time ago], there was a voluminous literature and [statistics to deal with the problem] was a solved problem, so I’m a little troubled that you seem to be trying to invent your own methods and aren’t citing […]

Earlier posts: Something about certainty, proofs in math, induction/abduction, Is the summed cubes equal to the squared sum of counting integer series? The things I’m going to say for math are equally true for logic, so whenever I write “math”, just mentally substitute to “math and logic”. Here I’m going to be talking about something […]

In the review of a paper submitted to ODP some time ago, the issue of a general extremism factor in religion came up. Unfortunately, Dutton deleted the submission thread, so the discussion is forever lost to history (possibly could be recovered from backups of the forum, but not worth the trouble; Yes I looked at […]
