Halo Effect

The tendency to let a positive impression in one area influence your overall judgment of a person, brand, or product.

Our brains love coherent narratives. If someone seems good in one way, we unconsciously assume they're good in other ways too, creating a 'halo' of positivity.

• Assuming an attractive person is also intelligent and kind.
• Trusting a celebrity's opinion on health because they're famous.
• Rating a product highly on all features because the packaging looks premium.

• Evaluate each quality or trait independently.
• Ask: 'Am I judging this based on evidence, or based on an unrelated positive impression?'
• Seek objective data rather than relying on first impressions.
• Be especially critical when charisma or aesthetics are involved.
