Honest Tea is trying to see just how honest people in the United States are. They've been conducting a social experiment on Americans for the past few years to see who is honest and who isn't so honest.

The experiment is simple. Honest Tea set up a display of free tea and a box for those who pass by to put in a dollar. The whole experiment is based on the honor's system: Take a bottle of tea, leave a dollar. So how did Americans do? The experiment was done in over 60 cities in all 50 U.S. states.

The most honest city in the experiment was Honolulu, and the most honest state was Alaska. Honolulu got a 100 percent rating, and Alaska received a 98 percent. The U.S. as a whole received a 95 percent rating.

Honolulu's 100 percent rating is the same as last year's. Improving the most from 2013 to 2014 was Washington, D.C., the city rised to 96 percent honesty from 80 percent honesty last year.

Taking the honor for the least honest city in the U.S., according to Honest Tea's data, was Providence, Rhode Island. They received only an 80 percent honesty rating.

The 95 percent rating that the U.S. received shows that more people put the dollar in the box before taking the tea. In 2013, only 92 percent of Americans put the dollar in the box before taking the tea. 

"We seek to infuse honesty into everything we do from the way we run the company to the organic ingredients we use, so we developed this experiment to see if people around the country share that same value," said Seth Goldman, co-founder and TeaEO of Honest Tea. "The 95 percent honesty rate that we saw this year suggests that Americans are a lot more honest than we give ourselves credit for." 

All the money collected from the social experiment will go to FoodCorps, according to Honest Tea.
