The trashy tabloid Weekly World News published an article—“Water from Mountain Falls Can Make You a Genius”—stating that drinking water from a special waterfall in a secret location in Switzerland “boosts IQ by 14 points—in the blink of an eye!” (exclamation point in the original). Hans and Inger Thurlemann, two hikers lost in the woods, drank some of the water, noticed an improvement in their thinking, and instantly found their way out of the woods. The more water they drank, the smarter they seemed to get. They credited the “miracle water” with enhancing their IQs. They brought some of the water home to their friends, who also claimed to notice an improvement in their thinking. Explain how a reliance on anecdotes led the Thurlemanns to perceive an illusory correlation.
