If you can believe in a flat earth you can believe in anything!

This is rather interesting article about the percentage of young people who are not so sure if the earth is flat or not: Do People Really Think Earth Might Be Flat?

Despite conflicting statistics, one line that jumps out:

Firm belief in a flat Earth was rare, with less than a 2 percent acceptance rate in all age groups

Seems to me, if you can believe in a possibility of a flat earth then you can believe in anything. What does that tell us about human nature?
