"Human behaviour is alarmingly complex."

I'm starting to think I'm the only one that doesn't think this way, but I know that isn't true. As a survivor of chronic depression, I see human behaviour as extremely simple and basic, perhaps alarmingly so considering the power we wield :P

The fundamental rules and concepts in human behavior appear to be simple and in many ways exactly like those in our mammalian cousins. Freud realized this and warned that we should not regard everything as motivated by sexuality; but imho, he was probably just scared of what he saw. At the core, we are primitive animals; but on top of that, the complexity of our society and cultural laws require a big, creative brain to sell ideas and inspire collaboration. When it fails, we resort to aggressive and segregational behavior.
