My grandmother tells the story of the head shaving folk belief. Apparently even though my Grandmother received her cosmetology license in the U.S., and throughout her training they never told her it was true and she never saw any evidence that it was true but she firmly believed in the Colombian folk belief that if you shave a person’s head who has curly hair at a young age then the hair will grow back straight especially if they are very young. So my Grandmother, who hated my mom’s curly hair because it was too hard to style, tried many times to sneak up on my mom while she was sleeping and shave her head when she was a young child (4-8) but always failed because my mom would always wake up screaming. To this day my mom is an extraordinary light sleeper.
Analysis: Even with empirical evidence some folk belief is so strongly ingrained that people will act when it seems against someone else’s best interest. The concept of shaving a five year old girl’s head seems to border on abusive, but the folk belief was so ingrained that even to a highly trained professional the folk belief still remains plausible. Perhaps this is why, even among highly trained brain surgeons like Ben Carson, belief in creation myths remains so strong.
