QUESTION: ON IMPULSIVITY (TIME PREFERENCE) AND POPULATIONS

What is the percentage of individuals with high time preference (high impulsivity) that will block the creation of norms, and therefore institutions, consisting of low time preference (low impulsivity)?

I have been trying to get my arms around this problem for the past few years, and my travels lately, into a low trust, but low impulsivity society have helped me understand it a bit more clearly.

Unless groups with low time preference have the right of exclusion (ostracization) then there is no defense against even ten percent of the population having a high time preference.

I know that at something under ten percent, populations stop integrating and start seeking identity and political power. But at what point do populations of high time preference individuals, regardless of identity or power seeking (no elites to represent their interest) prevent the formation of low time preference norms and therefore low time preference institutions?
