A good idea taken too far. Yes, psychological tendancies can be inherited, yes, they do affect your chances of mating, and yes, mainstream psychological theory glosses over this. However, most evolutionary psychologists seem to focus more on replacing current theory completely than supplementing it. As a result, a good idea gets seen as bullshit, partially because it fails to take environment into account, but mostly because its proponents are too caught up in their "revolution" to acknowledge the work of anyone outside of their own particular specialty.
