People hate when you tell them if they are easily predictable- because they aren't. Charles is doing the typical thing that people in tech do where they extrapolate their very confined research to the remarkable complexity of human life. There is a certain range of things that of course are predictable- in a way which is very trivial. Like what preferences a person has for food, what they buy....what websites they visit etc. But for deeper things like how trustworthy they will be in particular situations....how resilient they will be in particular situations etc- those things are far more complex- and also the only things people really care about. <br><br>People wince at statements like 'people are easily predictable' because they know it certainly is not true at a very deep level- the smart, often arrogant tech person will come in with assumed authority from their academic position and statistics that bear no real relation to the sweeping statement that has been made. I find that such people often harbour some form of resentment against human beings- and have a desire to minimise them/act like their technical research gives them an oracle-like level of insight that places them in a superior position to others. When it comes to complex questions about how humans are- statistical analysis is almost worthless. The only thing that can address those questions is wisdom from human experience.....and we all know very well that people are not predictable when it comes to non-trivial things- in fact we organise much of our lives and energy around the question of who we can and cannot trust....something we would not do if people were predictable.
