Does “Humane Meat” Bring People Closer to Veganism?



Debunking the claim that “humane meat” is a positive step toward veganism, my good friend and fellow vegan, Sherry F. Colb author of Mind if I Order the Cheeseburger, posted this essay on Dorf On Law today and encouraged me to share it. I encourage you to share it as well.

The Fallacy of the Claim That “Research” Shows That “Humane Meat” Brings People Closer to Veganism by Sherry F. Colb

Over the last few months, I have repeatedly heard a peculiar claim articulated by a variety of vegan advocates on different vegan outlets. The claim is this: Even though it might seem that people consuming so-called “humane” animal products poses an obstacle to the movement for veganism, “research” shows that the opposite is true. “Research” shows that when people decide to purchase “humane” animal products, this choice increases the odds that those same people will eventually decide to become vegan. When I first heard this claim, I was intrigued. Could it be that animal farmers encouraging people to purchase their “local, sustainable, and [allegedly] humane” animal products were actually helping the vegan cause?

The answer is that the research on which people have based this conclusion gives us no reason to imagine that “humane” animal products bring people closer to veganism. My own conclusion, based on a combination of logic, experience, and my own anecdotal observations, leads me to believe that in fact, the opposite is true, that encouraging people to consume so-called “humane” animal products poses a major obstacle to the continuing spread of veganism. But quite apart from what I think, the research that supposedly supports the utility of encouraging the consumption of “humane” animal products in moving people closer to veganism does no such thing.

How can I say this? Well, let us consider what the research actually shows and why the conclusions people have drawn from that research do not at all follow from it. Here’s the supposedly revolutionary finding: It turns out that people who purchase animal products labeled “humane” (or “compassionate” or some other equally misleading adjective) may be more likely eventually to become vegetarian or vegan than are people who do not purchase these products. That is, there is a correlation between people buying animal-derived products labeled “humane” at point 1 in time, and people reducing or ending their consumption of animal-derived products at point 2 in time.

As everyone knows, a correlation does not necessarily indicate causation. But the problem with drawing the inference that vegan advocates have been drawing from the above finding goes well beyond the “post hoc ergo propter hoc” fallacy. Enter “selection bias.” Selection bias is the reality that people will often self-select to engage in an activity at time 1 and whatever motivated that self-selection can also fully account for the same people’s choice to engage in another activity at time 2.

Consider the following observational study. I observe that one group of people spends a lot more money at the grocery store on luxury items such as truffle oil and saffron than other people do. I decide to keep an eye on these people, because I want to know what the impact of all of this supermarket-spending might be. Eight months later, I observe that this same group of people is embarking on much more exotic and expensive vacations in places much farther away from home than other people who did not spend as much money at the supermarket as this group did. I conclude from these observations that buying expensive food at the supermarket helps enable people to be able to go on exotic and expensive vacations eight months later. Wanting to go on such a vacation myself, I immediately begin to spend a lot more money on groceries.

This hypothetical example helps illustrate selection bias. The act of spending a lot of money at the supermarket did not help to make an expensive vacation possible. If anything, this act would appear to hinder one’s ability to take an expensive vacation, all things being equal, by depleting one’s bank account. However, the people who choose to spend a lot of money at the supermarket are often doing so because they have a lot of money. Their having a lot of money has caused them to feel free to spend a lot on groceries. Then, eight months later, because they started with a lot of money, more than other people have, they also had enough money to pay for an expensive vacation that the rest of the population cannot afford. If I were to take my observations as evidence that spending a lot on groceries enables one to take an expensive vacation, however, then I would probably end up undermining my own goal, and I would be doing so because I ignored selection bias.


A very similar dynamic seems likely to be in play when we observe that the people who purchase “humane” animal products at Time 1 are more likely than people generally to be purchasing only vegan products at Time 2. Buying supposedly “humane” animal flesh and secretions is something that many people do when they are driven to try to act more mercifully and ethically toward their fellow sentient beings. Years ago, before I became vegan, I tried to buy containers of cows’ milk (or what would more accurately be called the “lacteal secretions produced by a mother for her baby calf”) that said “grass fed” and “organic” on them, because I thought (erroneously, as it turned out) that this meant that the cows from whom the milk was taken (a) did not encounter human violence and cruelty during their lives and/or (b) were allowed to live out their lives in peace, eating grass, never having to be slaughtered. Eventually, I learned that my beliefs were nonsense (nonsense amply cultivated by those who sell animal products), and I made the decision to become vegan. It is hardly the case, however, that consuming (mis)-labeled animal products helped move me closer to veganism; if anything, it slowed me down by falsely assuring me that I was already “doing right by the animals” by avoiding “factory-farmed” products.

If you think about it, it is not at all surprising that people who feel moved to act ethically and mercifully toward animals will make up a disproportionate share of the people buying supposedly “ethical” animal products and a disproportionate share of the people becoming vegan. A third variable — consciousness about one’s obligation to refrain from inflicting unnecessary suffering on other beings — can fully account for people’s desire to do both things. Similarly, if you observe someone buying a vegan frozen pizza, such as Tofurky, at Time 1, you may be more likely than otherwise to observe that same person adopting a dog from a shelter (rather than purchasing a dog from a breeder) at Time 2. Yet no one would claim that eating a slice vegan pizza causes a person to adopt a dog from a shelter.

Ordinarily, it might seem harmless when people assume that performing act 1 causes a person to perform act 2, just because we observe that the same people who perform act 1 later perform act 2. But if the goal of citing this research about “humane” animal products is to alter the way that people conduct their advocacy, then it is anything but harmless. If someone tells me that he buys all of his flesh from a “humane” butcher and all of his lacteal secretions from a “humane” dairy farmer, this tells me that he is the sort of person who cares about animal suffering and wants to do what he can to reduce it. He has, however, been misled into thinking that what he is purchasing is the product of merciful treatment towards animals, when it in fact involves tremendous cruelty and harm to animals, and he is also (from a logical standpoint) less likely to become vegan than he was before, because he has managed to mollify his conscience by purchasing the “humane” product. Indeed, that is presumably why suppliers create the “humane” product in the first place — to keep animal consumers consuming animal products and to distract them from the actual humane alternative, vegan products. The purveyors of “humane” products could hardly be expected to label their products “humane” if they believed that such labeling would lead people closer to veganism.

I know that there are many people who are far more interested in the phenomenon of selection bias than I am and who have much more to say on the subject. I have nonetheless decided to write this post about selection bias, because I have felt an increasing amount of frustration upon hearing this claim about the counter-intuitive results of “research” that should be altering the way animal advocates engage with the public. The research may tell us that the people who consume humane animal products are, all things being equal, more likely to become vegan than the general population. But this plainly does not mean that consuming “humane” animal products moves people closer to veganism. And if you are hoping to take an expensive, exotic vacation, I would strongly recommend against spending large amounts of cash at the supermarket between now and your vacation time. You’re welcome.

Go vegan.

  1. Fred

    A few months back, while eating at a small diner in town, told the waitress I was a vegan, and she said “oh, I was a vegan for 6 years”. So asked her why she stopped being a vegan, she said she felt like she wasn’t getting enough nutrition on a plant based diet, then a friend took her to a farm where they had grass fed, free range animals, and that convinced her it was okay to eat meat again because the animals were treated in a humane way.
    So of course I had to tell her that she must be aware that the animals were still going to someday be loaded into a truck where they would be taken to a slaughterhouse to have their throats slit, their blood drained from their bodies and would then be hacked up into small pieces and sent off to supermarkets.
    Also asked her if she had thought off going to a nutritionist to find out what she was doing wrong with her diet, since, after all, here I am, a vegan for 46+ years, a carpenter by trade, avid mountain biker, kayaker, cross-country skier with more energy than any one person should have. And at 6′ 2″ tall, 220 lbs. clearly I’m not lacking anything in my plant-based diet.
    I will never understand how someone can find light then choose to go back to darkness.


    • Well said, Fred. Lately I’ve been having friends of mine on Facebook justifying themselves in the same way. Making sure they let me know how humans their meat sources are. I think there has to be a psychological explanation for the obvious “guilt” they feel that forces them to justify their actions.

      They cannot truly believe they need to have animals killed for their food (protein) source. Can they?

      As always, thanks for commenting and share this piece.


  2. That was a fantastic read. I agree with you on your skepticism on selective bias. I too was tricked by producers of “humane” animal products and continued to eat chicken (seldom) and dairy and eggs (predominantly) thinking that my choice was a thoughtful one for those suffering. Of course, I learned soon after (thank you, Jenny Brown) the sad reality of farming ANY animal for human consumption — and promptly made the vegan switch.

    If only I had heard Brown’s interview on NPR sooner, I would not have delayed the logical choice, given my heart and mind was already firmly committed to avoidance of causing others to suffer. I believe the researchers are missing something in their analysis. Animal producers have a stake in keeping us all misinformed.


    • Thanks for commenting. The author of this piece is a good friend of mine and she has written an incredible book for vegans titled “Mind if I Order the Cheeseburger” that addresses more points like these. Vegans are subjected to so many odd questions and Sherry can answer them all!


  3. Very interesting!

    I’m taking a course online through called “The Meat We Eat.” I’m vegan, but I’m taking the course to see what is being taught about meat production, labeling, inspecting, etc. Animal ethics is obviously not on the syllabus. I also thought it would be neat to do vegan advocacy there. 🙂

    Anyway, this week, we are supposed to be discussing animal welfare and humane labeling. I shared this article on our discussion board. I know for me, I did try to buy “humane” products before I went vegan. I know now that there is no such thing as humane. I’m interested to see how the people in the course respond. There are some vegetarians in the course, but no one else has outed him or herself as a vegan yet.


    • This is great! Would love to know what happens. I love that you’re the “embedded vegan.” Let me know if you’d like to guest blog post your findings.

      Thanks for commenting!
