Steven Pinker's list of dangerous ideas

Here (via Tyler Cowen). A few of them are really discomfiting. Here's a sample of some that might be relevant for prediction markets:

Do women, on average, have a different profile of aptitudes and emotions than men?

Has the state of the environment improved in the last 50 years?

Would the incidence of rape go down if prostitution were legalized?

Do African-American men have higher levels of testosterone, on average, than white men?

Is homosexuality the symptom of an infectious disease?

Do parents have any effect on the character or intelligence of their children?

Would lives be saved if we instituted a free market in organs for transplantation?
