I believe the point here goes along the lines: ``instinctively, one perceives the fraction as (N-1 / N)'' -- where N is size of the group in question and the -1 is oneself... Which curiously renders oneself as a not-very-smart one. Which suggests one underestimated the fraction ;-) Especially as the two supporting points (a: unpleasant letdowns; b: frequent bothering ``at the wrong moment'') are quite subjective. To quote the venerable fortune(6): Renning's Maxim: Man is the highest animal. Man does the classifying.
