I think burnout fills the same sort of role. When people are constantly called to take on risky, stressful, and high effort activities - essentially, those that raise your cortisol levels - they burn out. Not just one-off ones, but repeatedly over long periods of time. So long-term high cortisol levels paint a picture of a certain narrative/social situation, where it's very much in your interest to "shirk" but you haven't been able to manage doing so because of narratives or social pressure. So your body "helpfully" removes the option of yielding to social pressure to rise to the occasion by making you unable to rise to the occasion in a way that cannot yield to the demands of others.
