Instead of 4 years of physical education, we need to give kids 4 years of scientific training. Science education focuses on helping people see what is there, not what they want to be there. I'm not going to pretend that scientists are perfect and non-biased - they are human beings, after all - but scientists learn to question their belief systems in order to draw out what is probably true and what may not be. Unfortuneatly, when somebody who is willing to doubt themselves comes across somebody who isn't, the doubter tends to be perceived as weak and indecisive. If more people recognized that a willingness to doubt is a strength, not a weakness, the world would be a much better place, imo.
