I thought Robin meant: Let the Less Wrong community sort through the information and see if there is a consensus arises on one side or the other. In this case no one has a "right answer" in mind, but we got a pretty conclusive, high confidence answer in the Knox case. Maybe we can do that here- we'd just need to put the time in (and have a well-defined question). Yes, there aren't many biochemists among us. But we all seem remarkably comfortable reading through studies and evaluating scientific findings on grounds of statistics, source credibility etc. Also, my uninformed guess is that a lot of the science is just going to consist of statistical correlations without a lot of deep biochemistry.
