Male chimps can be jerks. True, females can also be jerks (see: Chimpanzee, Jamie), and not all males are jerks (at least not all of the time). There is an exception to every rule. Nonetheless, it is undeniable that chimpanzee jerkishness has a certain maleness to it, just as chimpanzee maleness contains a certain jerkishness.

But just as not all male chimps are alike, so too is it true that not all jerks are alike. While this is by no means an an exhaustive examination of the topic, here we will distinguish between two types of jerk: Those jerks who wreak havoc blindly, as if possessed, and those who inflict their jerkiness with forethought and intention.

To illustrate the former, let’s turn to our dear friend Willy B. Today I watched him sit peacefully in the shade beneath a climbing structure on the Bray, his 2-acre habitat, surveying the yard for remnants of a the day’s forage. When the forage was finished, he quietly returned to the indoor enclosures. It being mid-afternoon, however, this peaceful Dr. Jekyll was suddenly and inexplicably transmogrified into a raging Mr. Hyde. Apropos of nothing and with no other chimps in sight, he began to bang on the food chute with the back of his wrist. The noise and vibration shattered the calm of the afternoon and soon the others were up from their naps. With hair on end, they circled each other in the confines of the front room area. Some began to pant hoot, which in turn raised the tension in the room even further. Minutes went by. The banging was incessant. Others began to stand bipedally and swagger. Bang, bang, bang. The noise swelled and soon came to fully occupy the space where thoughts would normally occur, making it impossible to do anything but join in the chaos. Bang, bang, bang…

BANG! A fight breaks out. The swirling mass of chimpanzees, now screaming, races from the front rooms through the chute and out to the Bray. Willy B climbs to the top of the tower and, with a fear grimace, watches as the other chimps threaten and hit one another. But he is not angry. Instead, he is scared and confused. Because he is once again Dr. Jekyll, wondering what on earth could have caused such tumult below.

Interestingly, this fight contained within it, and was indeed amplified by, the actions of our second type of jerk. Are you familiar with the admonition, common in both comedy and politics, to never punch down? For male chimpanzees, punching down is not only accepted in certain circumstances but is in fact a right of passage. As Craig Stanford states in The New Chimpanzee,

[Adolescent male chimpanzees] don’t submissively pant grunt to one another, and dominance among them is hard to discern. But once a young male reaches adulthood, he begins to climb to higher rank by taking on and intimidating each adult female. When he has risen in status above the most dominant female, the young male finds himself at the bottom of the male dominance network. Only time and repeated jousts with higher-ranking males will determine his ultimate highest status. (p.42-43)

According to some researchers, adolescent male chimpanzees routinely harass adult females as a low-cost way method of honing their competitive skills before testing them in the much riskier world of male competitive dominance. Gordo is well beyond adolescence, but his actions are often reminiscent of a chimpanzee stuck permanently in the liminal space between the female and male hierarchies. While size does not dictate rank, his more diminutive stature makes it unlikely that would challenge Cy, Terry, or Willy B directly. His social skills are of little help, either. He is able, however, to dominate Honey B. Usually.

As the dust on the Bray began to settle, the chimpanzees worked their way through the chute and back to the greenhouse. The screams had subsided and all that remained was Honey B’s diminishing whimper. This, thought Gordo, was the perfect time to assert himself. As she approached him, he hit her across the back and ran straight back to the Bray, knowing that she was afraid of the outdoors and wouldn’t have the courage to follow him.

He reached the platform and turned to watch Honey B screaming at him helplessly from the end of the chute.

Is it any less indecent for Willy B to cause daily disruptions to the harmony of the group simply because they are born out of blind rage and not malice? I make no claims as to the relative moral status of these two varieties of jerkishness. Nor, again, do I intend to cast all males as irredeemably jerkish. But in my experience, they do seem on average to contain each type of jerkishness in greater proportion than their female counterparts.

And as to whether these same tendencies prevail in my own species, I claim ignorance.
