Description
Summary:Bartlett (1983) reported favorable results in a test of Wherry's (1952) on for statistically suppressing illusory halo. In this study, a methodologically independent criterion was used to test the hypothesis that Bartlett's methodology artifactually confounded his predictor and criterion measures. Ratings on discriminating and nondiscriminating items from a forced-choice scale were used to predict methodologically confounded and methodologically independent performance ratings. When Bartlett's methodologically confounded criterion was used, a strong suppressor effect was found for low discriminating items, as in Bartlett's research. When the methodologically independent criterion was used, no suppressor effect was obtained.
