Halloween

This may not be good news for your waistline, but your sweet tooth might appreciate it: Halloween candy sales are crackerjack this year.

"Consumer confidence is riding high, so consumers are likely to splurge a little more on edible goodies," David Deull, a senior economist with IHS Markit, said in his analysis of 2017 Halloween spending.

Halloween candy sales are expected to rise 4.1 percent from last year, reaching a seasonally adjusted $4.1 billion, he said.

Halloween plays on our fears and our fantasies.

We craft haunted houses and scary decorations to evoke particular emotions. We choose our costumes to reflect something about the kinds of people we are or want to be — edgy, sexy, funny, clever. For children, Halloween is an experiment in delayed gratification and negotiation — which candies to eat now, which to trade, which to save. It's no surprise, then, that Halloween might reveal interesting features of human psychology.

But you might be surprised by just what we can learn.
