In 2010, Lance Storm, Patrizio Tressoldi, and Lorenzo Di Risio analyzed 29 Ganzfeld studies from 1997 to 2008. Of the 1,498 trials, 483 produced hits, corresponding to a hit rate of 32.2%. This hit rate is statistically significant with Participants selected for personality traits and personal characteristics thought to be psi-conducive were found to perform significantly better than unselected participants in the Ganzfeld condition. Hyman (2010) published a rebuttal to Storm "et al". According to Hyman, "Reliance on meta-analysis as the sole basis for justifying the claim that an anomaly exists and that the evidence for it is consistent and replicable is fallacious. It distorts what scientists mean by confirmatory evidence." Hyman wrote that the Ganzfeld studies were not independently replicated and failed to produce evidence for psi. Storm "et al". published a response to Hyman stating that the Ganzfeld experimental design has proved to be consistent and reliable, that parapsychology is a struggling discipline that has not received much attention, and that therefore further research on the subject is necessary. Rouder "et al". 2013 wrote that critical evaluation of Storm "et al".'s meta-analysis reveals no evidence for psi, no plausible mechanism and omitted replication failures.
