Kingston (J Comb Theory (A) 20:357–363, 1976) and Anderson (J Comb Theory (A) 23:363, 1977) show that the probability that a given contestant wins a bestof-2k+1 series of asymmetric, zero-sum, binary-outcome games is, for a large class of assignment rules, independent of which contestant is assigned the advantageous role in each component game. We design a laboratory experiment to test this hyp...

There is hardly any philosophical disc...
