Halo Effect
Our overall impression of a person influences how we feel and think about their character.
The halo effect is the tendency for positive impressions of a person, company, brand, or product in one area to positively influence one's opinion or feelings in other areas. The term was coined by psychologist Edward Thorndike in reference to a person being perceived as having a halo. Attractive people are automatically assumed to be more intelligent, kind, and honest. Apple products' success in phones leads consumers to trust Apple's laptops and watches.

- Marketing Brand Extension Trust Brand reputation in one product category automatically elevates consumer trust in new product categories from the same brand.
- Everyday life Attractive Defendant Studies show physically attractive defendants receive lighter sentences on average, controlling for crime severity.

Biases are not only private errors. They are design targets — patterns deliberately engineered into interfaces because they reliably work.
- E-commerce Lifestyle Brand Anchoring Premium brands associate their products with aspirational lifestyles and beautiful models so the halo of those associations transfers to the products.
Recognising a definition is not the same skill as spotting it.
Two scenarios from the app, with distractors drawn from the same family of biases — which is what makes them hard.
A manager assumes an employee who volunteers for extra projects must be the most dedicated, even though some employees volunteer for visibility rather than workload, while equally dedicated colleagues may focus on excelling at their core responsibilities.
A consumer assumes a tech product from a major company must be the best available, even though large companies sometimes produce inferior products while smaller competitors innovate more effectively, and brand loyalty can blind consumers to objectively superior alternatives.
Biases rarely arrive alone.
