Excellent point! The old evolutionary arms race. I think in the end, the set of genes that wins this game of cat and mouse will be the one that has the strongest selection pressure. For example, being able to detect untrustworthy people might increase my survival chances by x%, and being able to fool people might increase my survival chances by y%. If x >> y, then one would expect that most modern-day humans would be good at sniffing out untrustworthy people; if y >> x, then modern-day humans would have difficulty doing this, since the untrustworthy people have evolved an extremely strong ability to escape detection.
