I have been in the risk management field most of my career. My team can build a Regression analysis outcomes based model that can predict human behavior of almost any type. The primary reason that people are so predicable is that 99.9% of all humans are unable to compartmentalise their behaviors. Meaning they cross all areas of their lives. We have data banks full on human behaviors and billions of outcomes of different behaviors to mathmatically formulate models. You can ask as few as 9 and as many as 100 questions and pattern a persons behavior with less than a 1/10 of 1% error rate. It's how insurance companies, banks,credit card companies, the govt and many other industries and organizations assess risk. Big brother has been around along time and you are measured by it everyday unless you live in a cave.
