So, would you liken it to how we are able to predict a 'trend' in the movement of large groups of particles but when it comes to individuals it is too chaotic (or complex) for us to figure out?
Yeah, sorta'. But I think the term "firgure out" is somewhat misleading, since even as we're "figuring it out", the individual's morality is changing.
It seems that the individual is swayed by his direct environment, or local society. And his local society is swayed by the region. And the region swayed by the country. And so on ad infinitum.
In the old days, an individual's morality was, in fact, a product of his LOCAL environment and LOCAL society. That's not actually true in today's world other than third world nations.
Now an individual has tv and the Internet which gives him some connection, even if cursorily, to societies and other environments that he would never, ever have experienced before.
The latter part of that statement is ....well, pretty complex! And I'm gonna' have to do some serious thinking about it. I'm not sure who or what does the "swaying" in those examples/scenarios ...or how to figure it out.
Just a thought ...some individual designer in Paris might be the cause of changing fashions over much of the modern world. So, see, the influence isn't always so easy to figure out, or which direction it's going or coming from. And it's made worse, I think, by tv and movies and the Internet.
Back in the old days, 1700s and 1800s, a society was essentially isolated, and so the morality tended to be more isolated and more consistent, too. With the speed of communications, that isolation was lost, and the influences began to have an effect ...good or bad or both!
