Ok, it's a bit of a tricky one, I'm not sure if it's a pyscology or sociology type book I'm after..
I was browsing wikipedia yesterday and came accross 'bystander theory' which I found really interesting and wondered what books there are with a load of theories like the one I mentioned above?
or for example, a book looking into why humans behave like they do... Why do we drink? How do we chose who our friends are? why do we conform?
Type questions... a bit strange I know but I'm really interested in this kind of thing
