Halo effect: where it comes from

Edward Thorndike noticed that army officers who rated a soldier highly on one quality tended to rate him highly on every other quality too (Thorndike, 1920). He called it the halo effect.

In ads it shows up as loved stars, fine causes, beautiful craft and famous partners whose good name carries over to the product.
