Mckenheim (https://www.hs-augsburg.de/~mueckenh/Transfinity/Transfinity/pdf, p. 253) gives the following example which suggests that set theory causes perceptual problems or a partial mental disease caused by social pressure:Every day Scrooge McDuck earns 10 enumerated dollars and returns 1 enumerated dollar. If he happens to return the right numbers, he will get unmeasurably rich. If he happens to return the wrong numbers, he will go bankrupt.This result must be accepted by set theorists. Set theory claims that if McDuck always spends the dollar with the least number, then for every dollar of his income the day of spending it is fixed. And none remains. Obviously this is nonsense, because for every dollar that he spends, 10 others are received.How can this strange behaviour of otherwise intelligent persons be explained under psychological aspects?As an aside I quote a paragraph by mathematician N. Wildberger about social pressure in a related mathematical example:That would be like trying to get the high priests on the island of Okineyab to consider not whether the Divine Ompah's Holy Phoenix has twelve or thirteen colours in her tail (a fascinating question on which entire tomes have been written), but rather whether the Divine Ompah exists at all. Ask that question, and icy stares are what you have to expect, then it's off to the dungeons, mate, for a bit of retraining. http://web.maths.unsw.edu.au/~norman/views2.htm
