Being told something is generally the consequence of someone else’s desire to bring it to your attention – that there’s a deadline looming that you need to meet, that you need to be aware that a particular activity is forbidden wherever you are, or that your choice of outfit might not be showing you in your best light. Sometimes the information is useful, sometimes it’s inadvertently amusing (I always enjoyed a friend’s office door that had a stern ‘No Tapdancing’ sign on it, in case anyone was about to break into the best Fred and Ginger routine); sometimes, however, it can have effects that we can only assume weren’t intended.
Mark Gould, writing at his Enlightened Tradition blog, provides a personal example to illustrate this point – and an explanation as to why a reminder might not have the intended effect:
I recall reading many years ago about a study which suggested that waiting staff in restaurants tended to break more crockery when they were reminded to take care than when there was no such reminder. As I once washed dishes and made coffee in a wine bar, this made sense to me. There is a lack of trust implicit in a reminder, which might make one doubt one’s abilities and therefore lead to more breakages. An alternative explanation might be that the reminder causes people to concentrate on the wrong thing — a broken plate, rather than a plate conveyed safely to its destination.”
