What is the 'halo effect' and how does it relate to responsibility?

The 'halo effect' is a cognitive bias where the perception of one positive trait (like attractiveness or fame) influences the perception of other traits. The host discusses how this effect plays into the tendency to attribute responsibility to well-known figures, such as celebrities, for decisions that are not theirs. This can lead to misplaced blame or credit, as people often look to these figures as leaders or authority figures, thereby avoiding their own responsibility.
