This all depends on the valuation elicitation process, which is pretty clever and, assuming that the subjects are acting rationality, does in fact elicit true values—at least as implemented in the paper I linked. As the paper goes into, others unknowningly tweak this process a bit and change the incentive structure, then (surprise) they get WTP-WTA gaps.
