This is not a joke. Well not exactly ... more like an observation.
About 50 years ago, an educational psychology professor set up an interesting experiment. He would identify boys who, when tested, were of average intelligence. He would then tell their teachers that he had used a new IQ test, and found hidden intelligence, and even though the lads didn't appear to be brilliant, they were.
The teachers responded in the same way. In every case, they found the students to be brilliant, even though there was no objective evidence to reach that conclusion.
0'Stinky is not unlike those lads.
