Tinhats are people who believe ridiculous stories. They are low level paranoid people with no real understanding of science or research. The tinhat itself refers to the iconic foil hat worn by characters cowering from 'cosmic ray's, as portrayed in around a million hokey Hollywood films.

Aka conspiracy theorists.
The tinhats love a good 9/11 yarn.
