Assume the best possible interpretation of other people’s arguments

As we saw above, the basic way in which you implement the principle of charity is by assigning the best possible interpretation that you can to your opponent’s argument. The second important benefit to implementing this principle is that by attributing the best possible argument to your opponent, you mitigate the risk of the backfire effect. Since people are most strongly affected by this when they feel defense, abiding by the principle of charity and presenting your arguments in a non-confrontational manner that acknowledges the other person’s stance is one of the best ways to avoid this effect, and to make people more willing to listen to what you have to say.
