You'll see obvious shills and low IQs respond. Ignore them. Firstly, psychology and psychological warfare is fairly advanced at this point. Cause and effect is no mystery. Anyone claiming otherwise has revealed themselves to you. Additionally, we know research into psychology and behavior prediction of massive groups was well under way in the 1980s. To better understand this, look up asimov's psychohistory. Yes, it's real. We know this because this was used to control the stock market (government took control and shut it down, in turn confirming chaos theory), and eventually a confirmed DoD project out of universities. Which was eventually turned dark. Time travel absolutely is not required. Looking Glass is basically psychohistory. If you control enough levers on society they can very accurately predict the social response to them. It's far enough into the future because it takes time to pull the levers and allow for the new social reality to spread. Forcing more quickly it would in fact have a contrary effect as it would be socially perceived as inorganic and it would change our behavior away from the prediction. Bluntly, it's called science. Now look at those who claim science and psychology and psychological warfare doesn't exist.
