Interesting! Unfortunately, the link http://www.perceptionweb.com/abstract.cgi?id=p7175 doesn’t seem to work. I wonder if the study was retracted. In any case, given how many cards are in a deck, I suspect you’d need quite a few subjects in order to draw statistically valid conclusions. Jim On Thursday, April 12, 2018, W.

If you ask people to name a random card in a standard deck, what regularities govern their answers?
(Is this something someone has looked at?)
Cf. the observation that when people are asked to pick a number between 1 and 20, the most common answer is 17.
