The other day when I had to stop and get a tire fixed, I soon struck up a conversation with the repairman. Well, actually he struck up a conversation with me, but at first I was interested as he seemed to be quite a science fan. Unfortunately it didn't take long before I was informed of the truth of global warming and a dozen other subjects. Thanks to PF I think I finally have no debate left in me, and I was perfectly content to just sit and listen. What struck me most was his confidence that he has it all figured out. There wasn't even a hint of uncertainty. Yep, it seems that fixing tires gives one a special sort of insight that elludes even our best scientists. Also noted: He doesn't allow his HS aged kids to use computers. I understand the need to say that I believe this or that, but I have never understood why people fear "I don't know" as a position. And why it seems that the less educated a person is, the higher their confidence in all matters.
