Halo Effect

Halo effect is otherwise known as Horn’s Effect, devil’s and reverse halo effect is where individuals, brands or other things judged to have a single undesirable trait are subsequently judged to have many poor traits. Allowing a single weak point or negative trait to influence perception of the person, brand or other thing in general. Simplifying it, when we consider a person bad in one area, we are likely to make a similar evaluation in other areas.
