YouGov shared a fascinating chart from a poll asking Americans to estimate the size of groups. 3 things became evident.
First, Americans vastly overestimated the size of minority groups. Check out the difference in estimates of those who have >$500,000, are transgender, are muslim/native american/jewish, and so on.
Second, they underestimated the size of majority groups. More people are Christian, fully vaccinated against COVID-19, have flown on a plane, and have graduated high school than others thought.
Third, it demonstrated just how bad we are, on average, on estimations. Biases rule.
