Central architect of the quantum-cognition program: co-author of the 2014
PNAS paper establishing the QQ-equality order-effect result
([[claim-question-order-effects-follow-quantum-qq-equality]]) and of the
general hypothesis — that quantum-like models can account for both
question-order effects and the conjunction fallacy — that Boyer-Kassem et al.
(2016) subsequently reject
([[claim-boyer-kassem-refutation-rejects-non-degenerate-and-degenerate-models]]).
His work is the load-bearing target on both sides of the vault's
quantum-cognition scope-limit thread: the source of its strongest confirmed
success and its clearest documented failure.
