"It's not necessarily that we don't like to work, but when there are two ways of doing the same thing - one easy, one hard, we naturally gravitate to the easy way, that's the right answer," he says. "So the bias toward finding the easy way, means that sometimes we pick the easy way and we get to the wrong answer."
