I'm not thinking of anyone in particular, but in my experience thickos are usually the loudest and hardest people to shut up. Maybe it's their defence mechanism to force all conversation into the narrow channels where they can take part. Anyone else got a theory?
yeah, I reckon that people are more nurture than nature, cos they have to have the genes to commit certain behaviour. you cant say that people are a product of their environment.. because, say a brother and sister are raised in the same household and 1 turns into a serial killer yet the other doesn't. the nurture part of the argument can't really apply or they would both be serial killers.
Brashness is often an overcompensation for lack of mental ability. However, you'll also see that a lot of uneducated people are also very opinionated and will often use their confidence in speaking aloud to cover for the fact that they don't have all the facts to back up their arguments.
