Handwashing, Heliocentrism, and Global Warming: To Reject or Accept?

How often do you wash your hands? The Center for Disease Control recommends hand washing in numerous scenarios, such as before, during, and after preparing food, before and after tending to someone who is sick, before and after treating a wound, after going to the bathroom, after touching animals, and the list goes on. Now I know it might seem a little ridiculous to wash your hands as often as it is recommended, but I am crossing my fingers that you at least understand why it is necessary. One of the first things we teach our children is to always wash their hands, and how to do so effectively (such as washing for the duration of “Row, Row, Row Your Boat”… twice). If you don’t believe me when I say hand washing is deep-seated in our modern society, just look at the 3.1 billion dollar market for hand soaps (Nielsen 2016). I, for one, certainly get overwhelmed when I walk down the aisle at my local Target and have to choose between the exhaustive collection of soaps with which I can lather up. And if I don’t find any soap I like then I can make my way over to the various types of hand sanitizers nearby. We can credit Ignaz Semmelweis and his microbial discoveries for the normalization of hand washing in our culture, but can you imagine a world where we didn’t wash our hands? And even stranger – can you imagine rejecting the science behind it?

There is a cold crispness to the air, but the sun in the cloudless sky gives you the little bit of warmth you need to feel comfortable. It is an early November day, and it is time for the U-12 soccer championship. Maybe you are a player, a parent, a friend, even a referee here today. There are four teams here with the same goal in mind, to win all their games so that they get crowned champion. The Cheshire Rams are the ones you are hoping to win today. You do not know how the day is going to go because all of the teams here have had great records this season and are all very competitive for the title. Hours later, the Cheshire Rams have done it. They are champions! You are in the car riding back, and all you can think to yourself is “wow, I knew it would happen!”


What is Hindsight Bias?

Did you actually know that the outcome would happen as it did? The truth is, most likely not. Read more…
