Context Effect
- Filed under
- Too Much Information
The charge
Our judgment of an option shifts depending on what other options or surrounding cues are present. The same choice can look better or worse when the context changes.
How it operates
Evaluation is relative, not purely absolute. Nearby options create reference points that change perceived value, quality, and attractiveness.
Logged incidents
- Incident 01
A mid-tier pricing plan suddenly looks attractive only after a decoy enterprise plan is added to the pricing page.
- Incident 02
A candidate seems strong in one interview slate and average in another because the comparison set changed.
- Incident 03
A feature request feels urgent when discussed next to small polish items, but routine when discussed next to revenue blockers.
What to watch for
Ask yourself: 'Would I value this the same way if it were evaluated alone or next to a different set of alternatives?'
Recommended action
Score each option independently before comparing them, or use stable joint-evaluation criteria across all options. This reduces decoy-driven shifts.
Known associates
- Availability HeuristicWe judge how likely or common something is by how easily examples come to mind, not by actual frequency.
- Attentional BiasWe selectively notice certain kinds of information while overlooking the rest, especially information tied to…
- Illusory Truth EffectRepeated statements start to feel true simply because they feel familiar.
- Mere-Exposure EffectWe tend to like things more after repeated exposure, even when the repetition provides no new value.
- Cue-Dependent ForgettingInformation can be stored but hard to retrieve when the cues present at recall do not match the cues present…
- Mood-Congruent Memory BiasWhen we are in a given mood, memories that match that mood come to mind more easily.
