INTRODUCTION

English translation pending.

CORE DEFINITION

The contrast effect describes the systematic shift in judgement produced by the object evaluated just before, as when an interview candidate looks stronger or weaker than they are because of who preceded them. The filter is the practice of recognising that anchor and re-scoring against an absolute standard. The qualification is that relative comparison is legitimate when ranking is the actual task, so the filter should not eliminate it everywhere.

SCAFFOLDING EFFECT

Reduce cognitive load

- Use Anchor Detection: ask what you evaluated immediately before forming this judgement. - Use Absolute Re-Scoring: rate the item against a written standard with the preceding item out of mind.

Anchor fast decisions

Judgement is partly relative because the mind uses the most recent stimulus as a reference point. When that reference is irrelevant to the standard, the resulting score reflects the sequence rather than the object, so removing the reference and supplying an explicit scale restores comparability.
