The Halo Defense

LessWrong contributor Mateusz Bagiński has identified a logical pattern he calls the 'halo defense': responding to allegations of wrongdoing by highlighting unrelated positive traits of the accused, rather than addressing the allegations themselves. His examples include a community figure accused of deception defended as 'a great friend,' and a professor accused of sexual harassment defended simply because he was 'vital to the community.' The halo defense is essentially the halo effect in action — the tendency for a positive impression in one area to spill over into judgments about completely different areas. Bagiński connects this to related cognitive biases like the affect heuristic, where people let favorable feelings about one aspect of something color their overall judgment.
