their actually being able to perform as claimed, or to some other
factor(s) relevant to identifying the "odd pizza out": a human-cum-pizza
version of "Clever Hans", pehaps?

thus, in the binomial context ... i was assuming (rightfully or wrongfully)
that n=10 ... that is, if we SCORE across the 10 ... we could have scores
of 0 to 10 ... in terms of how many got the

Why not do a trial experiment where you in fact have one type of pizza?
Order all the same pizzas, and then split them into two (identical)
groups. Perform the experiment by randomly picking from the two groups
(as before) and feed

Using blindfolded Ss will deal with that problem, and g
