Not surprisingly, every single person on my ignore list has found their way into this thread, just as they found their way onto said list by being the worst offenders in their lack of ability to accept facts as facts and bring their opinions into alignment with reality.
I'll be the first to admit that I'm stubborn about my opinions. I'd like to think that this is because my opinions are based on a careful evaluation of available information and the utilization of logic to arrive at my conclusions. However, when I'm presented with (or, almost as often, discover for myself) a fact which contradicts what I thought was true, I will and often have changed my opinion to accommodate this new information.
I have to admit, I am amazed that you can read that article, describe accurately its effects, and not recognize that you are just as human as the people in the study.
