The smartest creature depends on what you measure. If it’s raw problem-solving, it’s the octopus. If it’s social intelligence, it’s the elephant. If it’s pure spite, it’s the crow.
But maybe the answer is simpler: the smartest creature is the one that knows when to stop arguing and grab a snack. In that case, it’s definitely the honey badger—which is now eating your chips.
So the next time someone asks you this question, just say, “It’s whichever one is currently outsmarting me.” And then quietly back away from the parrot.
