Here's the part that hit home today. Heffernan:
So what does that kind of constructive conflict require? Well, first of all, it requires that we find people who are very different from ourselves. That means we have to resist the neurobiological drive, which means that we really prefer people mostly like ourselves, and it means we have to seek out people with different backgrounds, different disciplines, different ways of thinking and different experience, and find ways to engage with them. That requires a lot of patience and a lot of energy. And the more I've thought about this, the more I think, really, that that's a kind of love.
That really made me rethink the world today.
