If I'm a lazy bum and mostly content to be a lazy bum I will stay a lazy bum. Any interventions that are not doable by a lazy person will not be done. But if I have even a slight preference for being awesome, and there's an intervention that is fairly easy to implement, I want to do it. Insofar as you'd prefer people who share your values to be NOT lazy bums, you should if possible encourage them to be self-improvers.
