Advocates of sociobiology have tended to be politically right-wing, while its critics have tended to be political left. There are many exceptions to this generalization, especially to the first half of it, but few would deny the trend altogether. If sociobiology is simply an impartial enquiry into the facts, what explains the trend? Why should there be any correlation at all between political opinions and attitudes towards sociobiology? This is a tricky question to answer. For though some sociobiologists may have had hidden political agendas, and though some of sociobiology's critics have had opposing agendas of their own, the correlation extends even to those who debate the issue in apparently scientific terms. This suggests, though does not prove, that the "ideological" and "scientific" issues may not be quite so easy to separate after all. So the question of whether sociobiology is a value-free science is less easy to answer than might have been supposed.
