Thomas Boyer-Kassem

Lead author of the 2016 experimental paper (with Sébastien Duchêne and Eric Guerci, arXiv:1606.03430; Theory and Decision 81:479–510) that supplies the vault's clearest empirical refutation of the quantum-cognition program's account of the conjunction fallacy — rejecting not just a narrow model variant but the general hypothesis shared by the field's own leading theorists (Busemeyer, Pothos). Anchors a four-claim cluster on what that refutation does and doesn't settle.
