Studies Shed Light on How Cheating Impedes Learning

Everyone knows it's wrong to cheat.  Yet there is a surprising percentage of students who do.  The approach this article took was a bit different - outlining several studies that showed how those who cheat believe they will do as well or better the next time around, regardless of their ability to cheat.  It's as if they lie to themselves about the cheating, and are truly convinced that the score or grade they obtained was rightfully theirs.  This is such a strange way of thinking to me; I've never cheated on a test in my life, and I can't imagine doing so.  What would be the point of taking it?  But what I found most intriguing about one of the studies illustrated in this article was that the cheaters actually scored on average higher than their non-cheating counterparts when they no longer had access to the answers and so could not cheat.  This was not commented upon in the article, so maybe it was a fluke.  I hope to be aware of these situations as a teacher myself; perhaps using mostly short answer and essay tests, rather than multiple choice, or mixing up the questions so they don't correspond with a neighboring student.  I'll have to ponder it further.
