Dear Dan,

I was wondering how you allocate (phân bổ, chia) candy during Halloween to make sure kids don't dishonestly take more than they should. I've thought of handing each of the children their candy, but that way the kids can't pick what candies they like best. Also, this method takes more time, which I don't have, and makes things less pleasant for me.

But if I leave a bowl of candy out without any oversight, I know what will happen: They're all going to take more than their share until the bowl is empty.

Beyond Halloween, this is a general question about honesty. One of the things we find in experiments on honesty is that if people pledge that they will be honest, they will be—and this is the case even if the pledge is nonbinding (or what is called "cheap talk").

Given these results, I would set up a table with a large sign reading "I promise to take only one piece of candy [or whatever amount you want them to take] so that there is enough left for all the other trick-or-treaters." Below the sign, place a sheet of paper for your visitors to write down their names (and, given that it is Halloween, use red paint and ask them to sign in "blood"). With this promise to take only one candy, the public signature in blood and the realization that if they take more candy they will deprive their friends of having any, I suspect that honesty will improve dramatically.
