I have a theory that people strive in areas they have confidence they can excel at. That might explain the hospitality of the poor, and jocks. I exercise my mind, because I am good at it. I am pretty sure that there are jocks out there that feel sorry for me. In fact, I am pretty confident they do, based on the sorrowful glances I receive at the gym.
I think the current interest in pseudo-science is a societal trend that will eventually reverse itself. My sister is a doctor, and we have talked about this at length. Doctors (and science) have been alternately revered and despised. Of course, they are neither gods nor devils. By nature of their calling, Doctors tend to be a conservative bunch. They prefer treatments that are proven to work, and are loath to try untested alternatives. I have seen this for myself, as my sister becomes very despondent when she loses a patient. ...and here we live in a society that is bored with uniformity, craves the latest trend, and demands consumer choice.
I partially blame the media, and the speed at which information (and misinformation) is disseminated today. Politics is no longer about issues, but polls. Vote for the most popular, or you are a dork! but...but...but... what does the politician stand for? What do they believe???
Average joe public walking down the street has a microphone thrust in his face. What is your opinion on....? Is he given time to study the issues? Does he talk to an opponent with differing views in order to help shape his own? Why does his opinion hold his weight? Because it is no longer about principles or issues, it is about popularity.
If people have given up on becoming self-informed, it is because they have somehow been convinced it is too hard to do, or will have no effect.
