Brandolini's law, also known as the "bullshit asymmetry principle," holds that "the amount of energy needed to refute bullshit is an order of magnitude bigger than what's needed to produce it." This truism highlights that while the battle against misinformation more generally must be fought "face to face," the larger war against belief in misinformation won't be won without prevention. Once people are set in their ways, beliefs are notoriously hard to change. Building immunity against false beliefs in the first place is the more effective long-term strategy.
