    Feeling the Future: Experimental Evidence for
    Anomalous Retroactive Influences on Cognition and Affect
    Daryl J. Bem
    Cornell University.

    The term psi denotes anomalous processes of information or energy transfer that are
    currently unexplained in terms of known physical or biological mechanisms. Two
    variants of psi are precognition (conscious cognitive awareness) and premonition
    (affective apprehension) of a future event that could not otherwise be anticipated
    through any known inferential process. Precognition and premonition are themselves
    special cases of a more general phenomenon: the anomalous retroactive influence of
    some future event on an individual’s current responses, whether those responses are
    conscious or nonconscious, cognitive or affective. This article reports 9 experiments,
    involving more than 1,000 participants, that test for retroactive influence by “time-
    reversing” well-established psychological effects so that the individual’s responses are
    obtained before the putatively causal stimulus events occur. Data are presented for 4
    time-reversed effects: precognitive approach to erotic stimuli and precognitive
    avoidance of negative stimuli; retroactive priming; retroactive habituation; and
    retroactive facilitation of recall. All but one of the experiments yielded statistically
    significant results; and, across all 9 experiments, Stouffer’s z = 6.66, p = 1.34 × 10-11
    with a mean effect size (d) of 0.22. The individual-difference variable of stimulus
    seeking, a component of extraversion, was significantly correlated with psi
    performance in 5 of the experiments, with participants who scored above the midpoint
    on a scale of stimulus seeking achieving a mean effect size of 0.43. Skepticism about
    psi, issues of replication, and theories of psi are also discussed.

        l'inizio dell'articoletto di nature in merito è un buon riassunto, ci sono articoli da tutte le parti su questa storia

        http://www.nature.com/news/replication-studies-bad...

        For many psychologists, the clearest sign that their field was in trouble came, ironically, from a study about premonition. Daryl Bem, a social psychologist at Cornell University in Ithaca, New York, showed student volunteers 48 words and then abruptly asked them to write down as many as they could remember. Next came a practice session: students were given a random subset of the test words and were asked to type them out. Bem found that some students were more likely to remember words in the test if they had later practised them. Effect preceded cause.

        Bem published his findings in the Journal of Personality and Social Psychology (JPSP) along with eight other experiments1 providing evidence for what he refers to as “psi”, or psychic effects. There is, needless to say, no shortage of scientists sceptical about his claims. Three research teams independently tried to replicate the effect Bem had reported and, when they could not, they faced serious obstacles to publishing their results. The episode served as a wake-up call. “The realization that some proportion of the findings in the literature simply might not replicate was brought home by the fact that there are more and more of these counterintuitive findings in the literature,” says Eric-Jan Wagenmakers, a mathematical psychologist from the University of Amsterdam.

        che è esattamente l'accusa che viene portata alle riviste di psicologia in tutto questo casino che è scoppiato.

        solo che qua non se ne puo parlare senno spunta malattia a buttarci in mezzo le pedonerie, però quella ricerca era veramente al limite, mancava completamente di senno ed è chiaro pressochè a chiunque, voglio dire: rasoio di occam, per tirare giù il rapporto di causa effetto non basta lanciare due dadi statistici, eppure è stato pubblicato così com'era.

        edit: in quelle europee (il lancet ad esempio) è da tempo che criticano a manetta certa tendenza usa a far passare di tutto, sopratutto californiana anche se in questo caso nyorkese, avevo letto un articolo, interessantissimo eh, di un tizio il cui pomposissimo titolo era "Prof. of Quantum Psychology", che è un campo inesistente, ma una idea di cui vale la pena parlare ovviamente, ecco, questi qua in california hanno già i "corsi di laurea" in quantum phsychology prima ancora che vengano gettate le basi ontologiche del campo stesso
        Deluso
