Anyway, I was mulling over the potential psychology of victim blaming, trying to figure out why people are more willing to lay blame on someone who suffered an ordeal rather than the cause of the suffering.
My guess would be that it is a self-preservation defense response. Someone hears about something horrible that happened, the first thing they try to think about is what they would do in that situation. Which turns into, "Well, if this person was SMART, like ME, maybe the horrible thing would not have happened to them!" Because it's much more reassuring to think that horrible things can be avoided, instead of accepting that horrible things just happen and sometimes there is nothing you can do, no matter how smart you are.
Just a thought. No idea if there's any real evidence to back that up, but it makes sense to me.
