At what step do you stop agreeing with this logical argument relating to animals? For each step, I’m also showing the percentage of disagreements on social media that involved this step (either direct disagreements with the step or disagreements with its premise). (There were a total of 63 such disagreements described across my posts on Facebook and X.)
Note: any time the argument mentions something being wrong or immoral, you can treat it either as referring to something being (a) objectively wrong (if you believe in objective moral truth) or (b) wrong according to your own personal moral values (if you don’t believe in objective moral truth).
Step 1: Mammals (like dogs, cats, and pigs) and birds (like parrots and chickens) are capable of suffering.
1.6% of disagreements shared with me on social media involved this step.
Step 2: It’s wrong to cause suffering to dogs and cats if the reason you do it is just because it leads to you getting a small amount of pleasure relative to the suffering caused (e.g., if someone finds it fun to kick dogs and cats, it’s immoral for them to do so merely for pleasure).
11.1% of disagreements shared with me on social media involved this step.
Step 3: It’s wrong to cause suffering to pigs and chickens if the reason you do it is just because it leads to you getting a small amount of pleasure relative to the suffering caused (e.g., if someone finds it fun to kick pigs and chickens, it’s immoral for them to do so merely for pleasure).
None of the disagreements shared with me on social media involved this step.
Step 4: It’s wrong to cause suffering to pigs and chickens if the only reason you do it is a small amount of convenience relative to the suffering caused (e.g., if kicking a dog or pig in the face is more convenient because it causes it to go into its pen a little faster, it’s immoral to do so merely for this convenience).
6.3% of disagreements shared with me on social media involved this step.
Step 5: It is wrong to cause suffering to pigs and chickens merely for pleasure and convenience, even if the mechanism by which you cause this suffering is by paying someone else who then creates the suffering (e.g., if you pay someone to kick an animal because you enjoy seeing an animal be kicked, or you pay someone to kick an animal because the animal is in your way, that is still immoral even though you didn’t cause the harm with your own body).
4.8% of disagreements shared with me on social media involved this step.
Step 6: On large factory farms in the U.S., most of the pigs and chickens suffer a great deal and experience more pain than pleasure (i.e., net negative utility) throughout their lives (e.g., most egg-laying hens live in tiny cages where they can barely move most of their lives, and pigs are often kept in crowded barns with concrete floors and no ability to roam).
11.1% of disagreements shared with me on social media involved this step.
Step 7: The vast majority of egg and (non-fish) meat products sold at stores in the U.S. come from large factory farms.
None of the disagreements shared with me on social media involved this step.
Step 8: By purchasing egg and pork products from stores that use large factory farms as the suppliers for these products, throughout your whole life, you increase the number of chickens and pigs raised on factory farms (in an expected value sense – just as predicted by standard economic theory regarding what happens to production when demand increases).
1.6% of disagreements shared with me on social media involved this step.
Step 9: The vast majority of people in the U.S. could switch to a diet that doesn’t involve eating factory-farmed pork and eggs without increasing the amount of money they spend on food (e.g., most could find an egg-free vegetarian diet that is as cheap or cheaper than their current diet, or a diet that otherwise avoids factory-farmed pork and eggs).
12.7% of disagreements shared with me on social media involved this step.
Step 10: The vast majority of people in the U.S. could switch to a diet that doesn’t involve eating factory-farmed pork and eggs without sacrificing their health (e.g., most could find an egg-free vegetarian diet that’s as healthy or healthier for them than their current diet, or a healthy diet that otherwise avoids factory-farmed pork and eggs).
19.0% of disagreements shared with me on social media involved this step.
Step 11: Something having been done naturally by our ancient ancestors, or being a tradition, or being a result of evolution, does not make something morally okay (e.g., even if it was common for humanity’s ancient ancestors to commit rape, or if a group had a tradition of committing rape, or if human evolution favored those who raped, that would not make rape any less immoral).
3.2% of disagreements shared with me on social media involved this step.
Step 12: For most Americans, the only sacrifices they’d be making to switch to a well-thought-through diet free of factory-farmed pork and eggs would be a reduction of some pleasure (if they enjoy factory-farmed pork and eggs) and a loss of some convenience (when alternative food is not as convenient to obtain).
22.2% of disagreements shared with me on social media involved this step.
Step 13: In most cases (e.g., when there aren’t overriding health concerns, dietary restrictions, or a lack of availability of alternative foods), it is immoral for Americans to buy most pork and egg products from most stores in the U.S.
3.2% of disagreements shared with me on social media involved this step.
Step 14: The majority of Americans are acting immorally in their current purchasing behaviors regarding pork and eggs, but most of them could switch their behavior without excessive difficulty so as to have more ethical food purchasing behaviors (e.g., by adopting an egg-free vegetarian diet, or by avoiding buying animal products that come from factory farms, etc.).
3.2% of disagreements shared with me on social media involved this step.
