In a blog post, Jerry Coyne regrets that many on the left outright rejects scientific data that seems to contradict their ideological stance. This is particularly acute when it comes to the confrontation between feminism or gender studies and biology. I say « seems », because science doesn’t tell us how the world should be, only how it is. Indeed, our tendency to look up to nature as the autority over everything can make us forget that fact. That is what one can call the « call to nature » pitfall.
