Giulia Terzian in Psyche:
You might worry about offending someone, or lack the time to articulate your disagreement. You may even find yourself in a conversational context so polarised that introducing an objection will likely backfire.
But sometimes there are better and stronger reasons for voicing our disagreements with others. Sometimes we have an outright obligation to do so. You probably should correct your friend, even if speaking up strains your relationship, when they claim that Pinochet was brought to power in 1973 by a democratic election, rather than a US-backed coup d’état. And you probably should risk alienating your nextdoor neighbour when she recounts advising her family members against vaccination because she thinks that a vaccine developed at ‘warp speed’ is dangerous. But how do we decide, in any given situation, whether to pipe up or instead let a false, unwarranted, misleading assertion pass?
