How we overcome the moral agony of being carnivorous

Like it or not, you’re a carnivore. You can eat meat or you can pass it up, but either way, spare yourself any moral agony — a new study confirms our brains are hardwired to justify such decisions to ourselves.

If a cow could eat you, it would. It wouldn’t give a hoot about your feelings. It wouldn’t kill you quickly or humanely and it certainly wouldn’t worry about whether it was right to make a meal of you in the first place. It would ask itself one question: Am I hungry? If the answer was yes, you’d be lunch.

In that one way, at least, the carnivorous cow would be smarter than we are. The hard truth is, we eat meat, we love meat, and our bodies are built to digest meat. It would be nice if we could pick the stuff off the trees, but we can’t. So apologies to goats and pigs and cows and chickens and fish and lobster and shrimp and all the other scrumptious stuff that flies and walks and swims, but you’re goin’ down.

That, of course, is the primal, flesh-craving part of our brain talking. But other parts — our softer, cuddlier, morally-tormented parts — are consumed by guilt over taking a life to make a meal.

The only way to reconcile our minds, to say nothing of our menus, is either to go vegan — try that for a week — or to convince ourselves that despite the critter murder we effectively endorse every time we tuck into a pork chop or a chicken salad, we are still somehow decent, somehow good. That takes some fancy ethical footwork.

The main dodge we usually rely on is the “animals can’t think so they never know what hit them” excuse. That may well be true when you get below a certain point on the cognitive scale. As no less a figure than Princeton bioethicist Peter Singer — whose 1975 book Animal Liberation launched the animal rights movement — told me in an interview a few years ago: “I think there’s very little likelihood that oysters, mussels and clams have any consciousness, so it’s defensible to eat them.”

That case gets harder to make as you climb the critter ladder, and even chickens — as sublimely dumb a bird as ever lived — must have at least a dim light flickering upstairs, never mind pigs or even octopi that exhibit complex behaviours and a certain cleverness. But as a new study published in Current Directions in Psychological Science shows, we’ve found ways around that problem too.

In a series of experiments and surveys, a team led by research psychologist Steve Loughnan of the University of Melbourne confirmed that while people across a broad range of cultures agree that the more mindful an animal is, the less defensible it is to eat it, we have a convenient way of deciding which critters think and which don’t.

If you like beef, you’re more inclined to believe cows can’t think; if you eat only fish, you’re likelier to see cattle as conscious, while the salmon on your plate was probably a non-conscious nincompoop….. Read the full essay
