While looking for an article to write about for my blog, I came across this article about how women who have had multiple marriages suffer more hair loss than those who are happily married. After reading the article I begin to think about the six principles of critical thinking. I feel that I could connect this article to four out of the six principles. One, ruling out a rival hypothesis because in the article it talks about how men's marital status did not appear to impact hair loss patterns and how going through a divorce may not be as troublesome for males as it is for females. Therefore, Dr. Bahman Guyuron who is the lead author of this study ruled out the chance of this connecting to men also. Secondly, this could possibly be disproven because we need to take into consideration sleep duration, smoking habits, and sun exposure that would also impact hair loss. Thirdly, Occam's razor deals with finding the simplest explanation and I believe we can say that stress from divorce is the simple explanation for hair loss in divorced women. Lastly, correlation vs. causation is definitely represented in this article because divorce doesn't cause women to lose their hair, stress from divorce can. There is a third variable that helps back up the study.
I believe the critical thinking principle of correlation vs. causation is the most useful when reading an article like this. From what I have learned in Psy 1001 I was able to read this article and understand that correlation does not prove causation. Therefore, it is not divorce itself that "causes" women to lose their hair; it is the stress that comes along with divorce that may result in some women losing some hair. Being this is a correlational study; we cannot draw a cause and effect response.
I found this article to be very interesting because of Dr. Bahman Guyuron's selection of participants in his study because he chose to use 66 identical male twins and 84 female twins to determine which external factors contribute to hair loss. Besides the fact that the number of female and male participants is different, I would have never thought to use twins in this kind of study. After reading this article I feel very bad for women who have gone through divorce because all of the stress it puts on them and the effects that it may have on their hair!
