Arguments are a necessary part of life, but they don't necessarily have to be fraught. Psychologist Dan Shapiro has identified three barriers to productive arguments: an us-versus-them identity, not showing appreciation, and a lack of affiliation. Breaking through these barriers requires us to be better listeners and to recategorize our sense of "us."
I hate arguments. I hate the way it feels when my blood pressure rises and the cortisol kicks in. I hate the frustration that comes from talking past one another or reaching an impasse on an important issue. I especially hate the awkward apologies I have to dole out the morning after — because I definitely shouldn't have said that, and yes, it was a cheap shot.
