Time-preference may differ between races.

I would like to see more research on this.


"There is very little solid research on whether time preference has a genetic basis. It is known to vary with ethnic background. For instance, in Trinidad children of Indian descent (ancestors from India) are less willing to accept a small piece of candy now rather than a larger piece of candy in the future than those of African descent (Mischel & Metzer, 1962). However, since most personality traits are strongly affected by genes with a substantial heritability, it is very likely that the ability to defer gratification is a trait with a genetic component."

I would be interested to read a Game Theory interpretation of this. In what environments would the two strategies be optimal? Perhaps the ability to defer gratification is a trait that is only eugenic in stable, predictable environments? In highly changing, unpredictable environments (especially one where you can't trust people to make good on their promises to pay up with their promised reward "later") the "get it while you can" strategy might be optimal.
