Halo Effect Removal
Updated 2026-08-10
INTRODUCTION
English translation pending.
CORE DEFINITION
A debiasing procedure built on the halo effect described by Edward Thorndike, in which evaluation of one attribute spills over into unrelated attributes. The core proposition is that overall impressions are assembled from a global feeling rather than from independent evidence, so each dimension must be scored separately and supported by its own data. The key qualification is that the separation must be genuine, since a formal scoring sheet can still be filled in from the same global impression.
SCAFFOLDING EFFECT
Reduce cognitive load
- Trigger identification: name the salient trait that is spilling into other judgments. - Dimension split: score each attribute separately with evidence for each. - Fixed weighting: combine the scores using weights set before the evaluation.
Anchor fast decisions
A salient trait, such as appearance, pedigree, or a single strong impression, generates an overall affective reaction. That reaction then biases the interpretation of ambiguous evidence in every other dimension, so the assessments become correlated rather than independent. Separating the dimensions and requiring distinct evidence for each breaks the correlation, which restores the diagnostic value of the evaluation.
