First impressions: How One Trait Colours Everything

Halo and devil effect

BiasesJudgement

Why can one good impression make us see everything about someone in a positive light — or one bad impression make us see only their flaws?

In this episode of Circuit Breaker: Rewiring Your Decisions, we explore the Halo and Devil Effect — the tendency for one noticeable trait to influence our overall judgment of a person. We look at how a single impression can colour the way we interpret their personality, abilities, and behaviour.

But how often do we see people as they really are — rather than through the lens of one first impression? Discover how the Halo and Devil Effect can shape our judgments, influence our relationships, and lead us to overlook the complexity of others.
