The importance of considering experimenter effects on outcomes in experimental studies dates back to the work of Rosenthal (1966), who documented the influence of a variety of experimenter characteristics (e.g., sex, ethnicity, attire, warmth) on study outcomes.

Wrapped up in the issue of replication difficulties and methodological artefacts is a concern about experimenter effects. In summarising his contribution, French asks for a reliable demonstration of psi with a medium to large effect size that can operate in the presence of skeptics.

Although a number of factors have been proposed to account for the apparent experimenter effect, including experimenter beliefs (see Parker, 1975; Sharp & Clark, 1937; Smith, 2003b; Watt & Baker, 2002; Watt & Brady, 2002; Watt & Ramakers, 2003) and experimenter psi (e.g., Palmer, 1997; Schmeidler, 1997), it is possible that the effect of the experimenter is psychosocial in nature.

Evidence for Psi: Thirteen Empirical Research Reports

In a previous paper (Parker & Millar, 2014) the crisis in psi research was related to the failure to deal with the psi-based experimenter effect. The myth here was that by studying psi like any other ability, as a normally distributed variable, progress would be made.

The reason may be that most psi-conducive experimenters preferred to believe in a social interaction theory of the experimenter effect rather than a psi-based one.

In addition to his critique of Kanthamani and Broughton (1994) and Willin (1996a), Wiseman (2010a) briefly mentions experimenter effects: "Perhaps the most far-reaching version of this 'get out of a null effect free' card involves an appeal to the 'experimenter effect,' wherein any negative findings are attributed to the psi- inhibitory nature of the parapsychologist running the study" (p.

Goal-oriented psi experimenter effects. The possibility that an experimenter influences the experimental outcome using psi is the most challenging form of experimenter effect.
