That doesn't really contradict the post. The equivalent in the swimming world would be the A lane swimmers who are secretly doping, and would have close to no chance of making it otherwise, at best a B or C lane swimmer without. They can still be superficially very friendly and cheerful people, almost exactly like the genuine, bonafide, A lane swimmers. Of course if you closely examined their every thought and action for hours on end you might end up with a different conclusion, but how many of those types of situations will the average HN reader ever encounter in their lives? For the vast majority of folks the vast majority of the time, nearly all genuine and false 'A's are indistinguishable.
