People were significantly more likely to recycle their cup when their names were spelled correctly: 48% did, as opposed to 26% of those who had no name at all and a paltry 24% of those who had a misspell.
"We are averse to trashing something that is tied to our identity," said Jennifer Argo of the University of Alberta, one of the authors of the study, "as it would be conceptually similar to trashing a part of the self, which makes people more likely to recycle."

The whole problem

Would you recycle this can?
When it comes to recycling, studies show that we can be easily swayed, and small details can produce big changes in behavior.
In another study, Argo and co-author Remi Trudel of Boston University discovered that when an object loses its original shape, its chances of being recycled collapse.
A crushed can, for example, is considered damaged -- as such, it's more likely to end up in the trash can than in the recycling bin: "When items become damaged, they differ from the 'prototype' or ideal version of that product, and as a result, they are perceived as being less useful. As consumers, we tend to equate things that are useless with garbage," Argo said.
Small bits of paper also usually end up in the trash can: People are less likely to recycle th
