I believe, Carol, that is referred to as "willful ignorance." Denying a scientific study because it conflicts with your bias is such tiresome pattern. Your opinion has nothing to do with fact. If you think something that has been researched is incorrect, I encourage you to do some research of your own. Go do some field work and read some books. If you can disprove what this article says by using the scientific method, your idea will have an inkling of validity. Until then, leave your opinion out of research.
