Steep time discounting is important in the way people integrate present payoffs vs future costs, with well studied effects on criminal behaviour. From a game theoretical perspective, a strategy may evolve as the game approaches final iterations, with corresponding effects on the likelihood of 'cheating'.
The question is, do you know of any research on how time perception is shaped by extremely salient societal changes (post war, post revolution, post any momentous event which splits cultural representation of time between 'before and after')?
The hunch here is that because the cultural paradigm or myth of revolutionary change is 'starting afresh', or 'dialing back the clock to 0', this may compress both our representation of recent history and our representation of the future.
