Get out of my head! (started low/no refined or starchy carbs recently and just read this article recently and thought "I must write something about this"). Seriously though, understanding human psychology is so invaluable to having a clear worldview and processing what would otherwise be confusing and potentially inflammatory actions by others. On that note Cognitive dissonance (http://en.wikipedia.org/wiki/Cognitive_dissonance) has to be one of the most powerful concepts I've learned about.

So much for my day of work...

Very interesting topic, thanks for sharing.
