Dr. Art Markman – Why We Like Round Numbers
This is the 500th segment of Academic Minute, and that is a cause for celebration. But, why do we like round numbers like 500? Why not celebrate the 471st segment instead? After all, 500 is a round number largely through the accident that humans have 10 fingers and toes rather than something mathematically elegant about the base 10 system.
There are two factors that combine to create this preference for round numbers. The first is familiarity. Starting in the 1960s, psychologist Robert Zajonc observed that people like things just because they have encountered them before. That’s why an insipid pop song that drives you crazy at the start of the summer becomes the defining sound of the season after you hear it a hundred times.
The centrality of round numbers based on familiarity leads to the second factor—landmarks. We love to use round numbers and anniversaries as times to celebrate achievements and evaluate progress. At the start of any venture, whether it is a business or a relationship, there is lots of excitement. After a while, though, the excitement dies down, and your actions become routine. Those routines—or habits—are done mindlessly.
Landmarks have two benefits. First, they provide an opportunity to celebrate a real accomplishment. That celebration can inject energy and excitement to liven up the daily routine. And second, landmarks create a time to analyze your progress. Are you happy with your life, business, or relationship? Are there things you would like to change? Those round numbers serve as a chance to make mindful the things in life that have become mindless.
So, hats off to Academic Minute. Let the celebration begin.
