Cheater detection...not so good?

New research that reiterates the findings that 'cheating detection,' picking ou liars and deceivers, doesn't seem that well honed in most humans. But, the interesting thing the researchers found is that ~1% of subjects were extremely good at picking out fakers. If this ability is heritable, it would seem to go against Leda Cosmides' idea that a 'cheating detection' module developed during the EEA to get around the 'free rider' problem, since the genes influencing this trait have not been selected toward ubiquity.
