Robin: Holy squidshit, Batman, what the hell does that mean?
Opportunity costs, guy. The costs--in time and other resources--that come as the result of lies caused consistent honest interaction to be selected for in groups. This made a drowsy sort of sense for a minute a while ago out of how individuals can benefit via lies--it's because honesty was selected for as a trait essentially of the group and if the individual isn't part of a group, the basis upon which honesty is selected for isn't there, allowing the traits of Bartle test Clubs to be more beneficial or less detrimental.
I'm really tired right now; so, if that didn't make sense worth much of a damn, then its nonsensibility is sensible.
