I haven't read or heard about these papers/pieces/whatever but was the science bad? did he just racist out all over them or did he have data that a scientist would normally have and stuff?
from some of the critics, it does sound like there were significant problems with his inferences, if not his data. but as far as i can see, the blog post was pulled, so we aren't being trusted to evaluate his research for ourselves. if someone knows where a copy of the original is, i'd be interested to see it.
