things you learn in school actually apply to the real world?

today i was driving home from getting a quick lunch at chipotle and i noticed there were a bad car wreck in the right lane.  naturally i wondered if they were all okay, and who out there can't stare at a car wreck when they pass it, so i was doing this and all of a sudden a topic from my psychology class popped into my head.  this topic happened to the be bystander theory.  this theory states that the more bystanders there are in a situation, the less likely it is that someone will step forward and offer help, due to the idea of the diffusion of responsibility that occurs in groups.  in layman terms, no one will help because they all think someone else is going to help, thus the idea of the diffusion of responsibility.  all of this information rushed into my head about 1.8652 seconds after i initially saw the wreck and i quickly decided to turn around and see if i could help in anyway.  when i finally made my way back around i noticed that traffic around the accident had begun to pick up and drivers were getting frustrated trying to work their way around the wreck.  by the time i got to the actual wreck and i was about to park i noticed that the drivers were both out of their cars and one of them was already calling in the accident so i knew my help was not needed.  this incident only confirmed the bystander theory in my mind in that in the whole time that it took me to get back around, about 3 or 4 minutes, into a position to help, no one else had stopped to see if they needed help.  from this experience i've come to the conclusion that everyone should take at least one psychology course in their lifetime.  not only did it make me more aware in this situation, it has made me think about other theories and how they actually apply to my life.  i think psychology is an important course for everyone to take because it is the study of behaviors and mental processes, or essentially how humans think and why they do the things they do.  what could be more important and valuable than a basic understanding of what makes humans tick?
