Are we really all just stupid cattle?

I need something to restore my faith in humanity. Right now I just believe that the are all stupid and incapable of common sense or of taking care of them selves. How do we fix this problem?

For reference

Talking to a woman for 10 minutes who asks your age and you say 37 during her pause and then she says I would have guessed 32 will set you back 20 min and a whole bar on a pub crawl.
