You and your friend are trying to decide whether or not to jump across a chasm. You want to jump across to the other side where you will be rewarded with delicious berries. You friend wants to stay put and eat the so-so berries here. So you decide to compromise: you each jump halfway across the chasm and die.
Not all situations are chasms, but the really important ones usually are. Compromise can kill you; go for consensus if you can. If you can’t, go alone.
