When I want to reinforce the need for critical thinking, I sometimes bring up the green coffee bean problem. In 2012, a research article entitled “Randomized, Double-Blind, Placebo-Controlled, Linear Dose, Crossover Study to Evaluate the Efficacy and Safety of a Green Coffee Bean Extract in Overweight Subjects” was published in the seemingly reputable journal Diabetes,…
Have you ever heard of Nordstrom’s? It’s a trick question. The name of the store is actually Nordstrom. There is no letter ‘s’ in the name. The same is true with Kroger and JCPenney.

While we are taught how to read words and sentences when we are young, we are rarely taught how to read paragraphs or books. And most of us don’t realize there are different levels of reading.

It might be time to debunk the Dunning-Kruger effect. For those who may not be familiar, in the 1990s Cornell University professors David Dunning and Justin Kruger conducted a now-famous experiment to test whether incompetent people were unaware of their incompetence.
