If you want to continue developing this line of thinking, I can think of a few questions you could explore.
Can you find historical examples of a culture changing their standards for some group (the honesty of politicians, the behavior of children, etc.)?
If so, was the change due to drift over time, was it organized and deliberate, or what?
Can you use your model to make any predictions about any concrete events that we should expect in the future, even if just on an intuitive basis, and even if you had only low confidence about those predictions?
