Malcolm Gladwell turned the biblical story of David and Goliath on its head by noting that the giant was actually much weaker than his opponent. So why, as Gladwell asks, do we continue to tell the story the way we do? Maybe it’s because we’re built to root for the underdog while fearing the giant. I think the same dynamic is at work in the payments field, with tech start-ups the traditional Davids and payments processors the Goliaths.
