Knowing less is better

Malcolm Gladwell argues that knowing less can be an advantage. This is based on a study in which kids in the US were asked which was a bigger city: San Antonio or San Diego. Many didn’t know. Kids in Germany were asked the same. Most knew: San Diego was bigger. Why? Because they’d heard of San Diego, but not of San Antonio.

P.S: A comment mentions that the actual difference in population between these cities is only 2%. So maybe the US kids were right to be unsure…
