One of the enduring myths of modern times is the idea that lemmings have a suicidal streak. Apparently, we have Disney to thank for this, at least in part. During the shooting of their 1958 nature film White Wilderness, the crew purchased a few dozen lemmings, shot footage of them from a number of different angles to make them look like a large herd, then drove them off a cliff in order to show them “hurling themselves into the sea.” It apparently convinced a lot of people—after all, would Disney lie to you?—but it just isn’t so; the real reason for mass lemming extinctions is quite different. You see, in the absence of sufficient predators to keep their numbers in check, lemmings tend to breed out of control and literally eat themselves out of house and home; when there’s no more food, they pack up and move, migrating en masse, looking for a new place with enough to eat. The problem is that lemmings don’t see very far, so if they come to a cliff, or a lake, or the ocean, then yes, they keep right on going and end up dead; but their deaths are accidental, not the result of some long-tailed death wish.
The upside of this myth, at least for lemmings, is that at least we’ve heard of them. If I asked you to name another animal that lives on the Arctic tundra, how many of you could? Granted, it’s not that lemmings themselves are all that interesting, it’s their symbolic value; but the symbol is powerful enough that it doesn’t much matter that the actual animal is really rather nondescript. When we hear “lemming” we don’t think “tundra rat,” we think of someone who’s easily led, who follows the crowd wherever they go; we have an image of an individual who lacks the foresight to see trouble coming, or the insight to ask where their leader is going. We think, in other words, of the kind of person who would blindly follow someone right over the edge of a cliff and not even think twice until they were halfway to the bottom.
Now, there are those who will tell you that lemmings are in the majority, that most people are mindless followers; they might even be right, though I’ve noticed that people who say that tend to be pretty arrogant about their own independence. In the last analysis, though, I think the real lesson to be learned from the lemming is that leadership matters, because the direction in which you go matters. Indeed, that’s even truer for us than it is for lemmings: unlike the rodents, we know there are obstacles out there, we have some idea what they are, and we can plan for them. As such, we can reasonably expect our leaders to see the cliff up ahead, and turn before they get to it.
And if they don’t? Well, we have one other advantage over lemmings: just because we’re currently following a rat doesn’t mean we have to keep doing it.
