what is stupidity?

I just watched a documentary about stupidity. it wasn't that good. i then wrote a rant about why it wasn't good with the intention of posting it on youtube. i think the rant was too long or something so i'll post it here instead(note this movie claimed there weren't many books written about stupidity):

ironically, this video was created very stupidly. it lacked substance. it contrived stupidity at its surface value. the reason that there are not a great number of books about stupidity is that scholarly books aim for much more specific matters. how about searching for books that describe the psychology of social interaction. I'm sure there'd be a number of books that describe and analyze why people commit seemingly stupid acts as a result of social mechanisms. the majority of the discussion in this movie was based on that aspect of "stupidity". other images and ideas of "stupidity" could be subdivided and more thoroughly analyzed as heightened emotions, or inconsiderations, or lack of eloquence, or laziness/lack of motivation. but none of that is really looked at. the human brain is also a muscle and just like working out, some people don't like to strain it, or challenge it. that's not exactly stupid, it's just motivationally challenged. this is such a shallow documentary created for the lowest common denominator. i actually found the smartest part was from the guy that wrote the book ignorance is bliss. the guy presented a well argued satire of the human condition.


anyway, that's my rant. if you want to see the video, it's here:

you'll have to search for the other 5 parts. it's not too hard.
