More than 90% of Americans unknowingly passed an informal test about honesty this month, according to the beverage company Honest Tea.

The company set up more than 60 unmanned kiosks around the U.S., with at least one in every state, offering cups of tea for $1. Each location included a drop box for the payment.

Overall, 92% of Americans who visited the stands paid their buck. In Alabama and Hawaii, everyone paid without exception. Folks in Indiana and Maine did almost as well, achieving a 99% honesty score.

But in Washington, DC, about 20% took a drink without paying. The least honest (after DC) were West Virginia (85% paid) and Texas and Kentucky (both 87%). The morality level in DC was so low that someone even stole a bicycle belonging to the Honest Tea’s founder.

Men and women were nearly equally honest, with females taking a slight edge, 95% to 91%. Blondes were more honest than bald people 95% to 90% and people who wore glasses were more honest than men with “5 o’clock shadow” 94% to 88%.
