Eh. Decius was clearly thinking of, and still is thinking of, substantial and longlasting effects rather than the almost trivially small disappearing effects confirmed by the followups and meta-analyses. That is completely unreasonable a view to hold after reading that review, and I would suggest that even that small nonzero effect is dubious since it seems that few to none of the studies fully accounted for the accuracy issue and there is obviously publication bias at play.
