I have been watching some of the videos from the Edge seminar THE NEW SCIENCE OF MORALITY. There will eventually be about 10 hours of talks and discussions posted on the Edge site. From the few presentations I have seen so far this looks to have been a fascinating seminar.

Partly because the science is relatively new – but also because there has been a lot of progress made. However, there are of course areas which promote intense discussion. I get the impression, for example, that several of the participants wish to challenge to dogma that one can’t determine an ought from an is. It’s going to be interesting to see that debate played out.

WEIRD culture and reasoning

Jonathon Haidt

Jonathon Haidt was the first speaker and made some interesting points about the relevance of a science centred largely around specialists from advanced western countries. He is using the acronym WIERD for the orientation around cultures in the Western, Educated, Industrialized, Rich and Democratic (WEIRD) societies. This analysis comes from a recent paper The weirdest people in the world ? by J Henrich, SJ Heine and A Norenzayan. Those authors say “we need to be less cavalier in addressing questions of human nature, on the basis of data drawn from this particularly thin and rather unusual slice of humanity.”

Haidt also discusses some fallacies about human reasoning. “The puzzle is, why are humans so amazingly bad at reasoning in some contexts, and so amazingly good in others?” Again he refers to a recent paper by Mercier and Sperber – Why do humans reason ? Arguments for an argumentative theory. This is an interesting paper discussing human problems like confirmation bias, the human problem of search for evidence to support an preconceived conclusion.

Obviously both these problems are very relevant to a seminar like this. Go to the Edge site for a video of Jonothan’s presentation or download and audio file (MP3 Audio Download – Jonathan Haidt Talk).

Sam Harris and a role for science

As Sam Harris was one of the participants the seminar will surely have also discussed his ideas on the role of science in determining right and wrong. He presented these ideas in two recent lectures and they resulted in a lot of discussion, and controversy, on a number of scientific blogs (see Can science answer moral questions? and
