Gh. Mumma et Sb. Wilson, PROCEDURAL DEBIASING OF PRIMACY ANCHORING EFFECTS IN CLINICAL-LIKE JUDGMENTS/, Journal of clinical psychology, 51(6), 1995, pp. 841-853
Primacy (or anchoring) effects in clinical judgment occur when informa
tion presented at an early stage unduly influences a judgment compared
to the effect of the same information presented at a later stage. Usi
ng recent theoretical models of these effects, three debiasing methods
were developed and tested for their efficacy. Contrary to some recent
failures to find anchoring effects, both single-cue and sequence anch
oring manipulations produced medium-size effects on personality trait
ratings and generalized to predictions of behavior. A consider-the-opp
osite procedure that involved cue sorting by diagnosticity debiased si
ngle-cue anchoring, but comparable results were obtained by subjects w
ho simply took notes while reviewing each cue prior to judgment. Bias
inoculation was marginally successful at reducing single-cue anchoring
. Methodological issues as well as suggestions for future research are
discussed.
