292: Ditzy girls, Gratitude, Quality of your internal audience, Empathy

Why do men seem to be so enraptured by "ditzy" girls? They trip over themselves trying to take care of her. Is it an behavioral manifestation of attractive estrogen levels in the woman? How did gratitude and gratefulness come to evolve in human beings. if one analyses it, it is an extremely complex highly advanced thought process about how bad a situation could have been and the fact that its not one must accept, acknowledge and recalibrate one's esteem cues and status so as to not be sad/depressed/ low about a certain event. How does one's personality influence the quality of the internal audience? I can imagine that someone higher in C would have a lower or maybe harsher internal audience. I am curious about a few inferences I made about the interface between environment and personality. High conscientiousness and agreeableness implies a higher likelihood of accepting and following social norms. In other words, these genetic traits are responsible for preserving the cultural environment. On the other hand, a person with high conscientiousness but low agreeableness is more likely to develop and carry out their own credo, based more on their personal experiences and judgement. Does any of that pass the smell test, or better yet, is there research that supports or disconfirms any of it? Over a period of million years, if we keep eating the way we eat (high fat salt sugar diet),would eventually those individuals get selected whose genetic variations are such that can tolerate the high fat diet and still survive for a hundred years. would that be a fitter, new species then ? Could you explain empathy , the processes involved, the CB that we run, etc through the lens of evo psych. Also is empathy a cognitive process or it is a means to an end i.e. a signalling device?
