But the author does include this cogent point:

Although there is no doubt that cheating does occur, and that it is an important issue, I think the incidence of cheating is greatly exaggerated. When one considers how many millions of chess games have been played, the number of proven and even accused cases of cheating is marginal. In fact, I would argue that there is a greater danger to chess in the perception of cheating than in the actual act. I know multiple players who have irrationally avoided playing competitive chess because they fear playing cheaters. Personally, in hundreds of tournament games, I have never once felt the least suspicicion that my opponent was cheating.
