I think there's still quite a bit of selection for intelligence - just look how pervasive "alternative" medicine is. All the time, people lacking in critical thinking skills are choosing to forgo real medical treatment in favour of crystals or homeopathy or voodoo dolls or whatever, and dying of what are often easily treatable conditions. Whereas those with critical thinking skills will choose real medicine, and be much more likely to survive.
