You’re free to hold wrong opinions. Humans in aggregate act remarkably similarly across time when faced with certain choices. It’s a downstream effect of our design (hundreds of thousands to millions of years of evolution). There are exceptions to every rule of course. That’s why large groups of people are easier to model, but not the individuals. Isaac Asimov demonstrates this concept brilliantly in his Foundation books. The idea of the Psychohistory is precisely that: based on the past you can model the behaviour of people thousands of years into the future as an aggregate, but the weakness of the model are certain contrarian individuals that the model cannot account for. These individuals drive most of the changes throughout human history. Jesus comes to mind as an obvious example, but you can dismiss him for being the son of God. There are other humans tho, who made considerable changes to society, although on a smaller scale. What you fail to realise is that you cannot break the cycle without breaking humanity, but you can make it shorter or longer and the highs and lows deeper or higher. But you definitely cannot quantify it with physics, at least not any physics humans actually know of yet.
