Which means if everyone goes along with the "mob think", you can predict what will happen.
But if someone actively goes against the "mob think", it makes it more difficult to predict.

On the individual level ... I suppose you can predict our lives to a certain degree.
After all, that's what an insurance actuarial does. Predict the risk of death/injury based on gender, age, ethnicity, and lifestyle.
