I just finished reading
Change of Heart: What Psychology Can Teach Us About Spreading Social Change, which has a lot of relevant ideas. The author is Nick Cooney, the founder & director of The Humane League. He doesn't have a lot of psychology credentials, so I'm not sure of his ability to critically assess the research (he relies a lot on pop-psych books such as
The Tipping Point, Influence, Made to Stick). But there's no other book that I'm aware of that applies psychological-research findings to changing people's attitudes about animal welfare (animal welfare accounts for maybe 2/5 of his examples; he also mentions environmental, labor, gay rights, etc.).
I thought it would be useful to summarize the book. What I wrote is a bit long, but much shorter than the book itself. If you want any of his references, I'd be glad to send them to you. And please criticize anything you disagree with. I tried to put things in my own words, but there is probably some unintentional plagiarism. Antepenultimate caveat: These techniques are not magical. It might be better to try to influence many people in low-quality interactions (e.g., passing out leaflets [or earning money to donate to Vegan Outreach]) than a few high-quality interactions. Penultimate caveat: Who knows whether laboratory findings will hold up in the real world‽ Final caveat: I haven't tried most of these things out.
EmpathyEmpathy avoidance is the tendency to avoid empathy-inducing experiences that will cause you to act in a costly way. For example, you might cross the street to avoid a beggar instead of continuing on your way and rejecting his pleas. In animal advocacy, people try to avoid media that show animal suffering if they are aware that a costly change (i.e., vegetarianism or veganism) will be asked of them.
An experience I had with my sister illustrates this phenomenon. She watches those Animal Planet shows in which the animals are rescued from abusive owners (including
Pit Boss, a show about midgets [!] who rescue pit bulls). She feels bad for the animals, but no behavioral change is demanded of her. But when I tried to give her one a Vegan Outreach pamphlet, she refused to even look at it, because she knew it would demand a costly behavioral change on her part.
We should strive to get people to feel empathy with animals, not just to feel bad.
Guilt/BlameIt's not effective to blame people for the suffering caused by their diets. So don't say, "In the last year, you've been responsible for the death and suffering of thirty-five chickens, etc." Guilt isn't effective at persuasion; making strong moral accusations usually just leads people to defend themselves. Instead, direct blame toward factory farms and frame veganism in terms of helping animals, as in one of the Vegan Outreach pamphlets: "By avoiding the meat of chickens, turkeys, and pigs, you can prevent the suffering of more than two thousand of these animals during your lifetime!" (It might be better to use smaller numbers, e.g., one animal every ten days or whatever, because of
scope insensitivity.)
Attitude-Behavior GapEven though less than four percent of Americans are vegetarian, twenty-five percent say that animals deserve the same rights as humans. Most people find the conditions that factory-farmed animals are kept in abhorrent, but few change their behavior because of it. Oftentimes, it's not people's attitudes that need changing; it's their behavior.
Social NormsPeople tend to go along with the behaviors that are well established in their society. Few people are vegetarians, so don't draw attention to this fact. Instead, say that
97% of Americans believe that animals deserve (at least some) protection and that the number of vegetarians is increasing. Organizations like PETA seek
endorsements from celebrities in part to make vegetarianism and animal rights seem more normal. The problem with this approach is that it gets people to do the right thing for the wrong reason; to spread concern for wild animals, it's better to get people to stop eating meat because they empathize with animals. But see
Cognitive Dissonance below.
If you're passing out leaflets and people are dropping them on the ground, pick them up: If people see that others have left them on the ground, they'll be more likely to do the same. And if several consecutive people have refused to take a leaflet, wait awhile; people are more likely to refuse if they've seen someone else do the same.
Cognitive DissonancePeople usually see their behavior as consistent with their beliefs. (The reason that people care about animal welfare but still buy factory-farmed meat is probably that they just don't think about the issues, or they think about them in silly ways.) If you tell someone that eating meat is wrong, she'll probably think, "But I eat meat, and I'm a good person. So eating meat
can't be wrong!" And then she'll raise some bogus objection that just occurred to her off the top of her head.
Cognitive-dissonance theory predicts that attitudinal change will often
follow behavioral change. If you can get someone to go vegetarian for any reason, she will probably be more sympathetic to animal-welfare issues because anti-speciesist beliefs will not conflict with her behavior. Vegetarians of all stripes (save deep-ecologists and perhaps those intent on "
honoring God's creation") should be more open to the idea of preventing wild-animal suffering. (I think Alan Dawrst has had some experiences that conflict with this theory; I remember his writing that some of the non-vegetarians he's talked to have been
more ready to acknowledge the badness of wild-animal suffering and our duty to prevent it than some vegetarians on online forums.) Nevertheless, it's better to focus on the arguments from animal welfare: Ethical arguments are more likely to produce lasting change than appeals to self-interest (i.e., health), and environmental arguments are likely to be counterproductive regarding concern for wild-animal suffering.
Costs/BenefitsDon't tell people that vegetarianism is hard. People don't want to do things that are hard. Tell them that it requires virtually no effort after you've been at it a few months (that's my experience, anyway). Once somebody gets started, she'll (usually) realize that it's easier than she thought, so the first step is key.
Emphasize that concern for animal welfare isn't an all-or-nothing proposition. Eliminating poultry, eggs, and fish from one's diet is almost as good (maybe better in terms of tangible consequences, given wild-animal suffering) as going vegan.
Availability BiasI'm always surprised when people tell me how hard veganism is. Part of the reason non-vegans think veganism is hard is that they don't know what foods they would eat. They think, "Yesterday I ate a steak for dinner. If I took away the steak, what would be left? Vegans must eat only lettuce." That's why the Vegan Outreach pamphlets include information on animal-product substitutes and meal ideas. Mercy for Animals offers a
vegetarian starter kit that includes several pages of recipes;
many more are available online (I haven't tested any of them yet).
SurprisesIf you want to get someone's attention, surprise her. When someone asks you why you're a vegetarian, tell her—then ask why she eats meat. One of Vegan Outreach's full-time leafleters says things like "That's a lovely smile you have" and "You look compassionate." That takes some serious
cojones.
Monitoring/FeedbackPeople are more likely to stick with a goal if they receive feedback about how they're doing. Cooney suggests using widgets that display the number of farmed animals that the user has spared owing to her dietary choices. Does something like this exist? I'm aware only of the
slaughter tracker, which is just depressing, on Gary Francione's website.
GapsWhen people realize they don't know something, they become more interested. So you might ask someone to guess how much space a hen in a battery cage has, or what a gestation crate is, instead of just telling her.
PlansIf you convince someone to go vegetarian, the battle is only half won—there are a lot of former vegetarians. If you've had a successful animal-welfare talk with someone, ask her if she intends to eat fewer animals and eggs in the future: Making a verbal commitment increases the chance that she'll follow through. (If you haven't been successful, don't ask; she'll probably say "no," and that will make it harder to change her attitude in the future.) Public commitments (telling friends) about a goal of becoming vegan can help. So can making concrete plans.
Foot-in-the-DoorIf someone consents to a small request, she'll be more likely to consent to a larger one later on. For example, if you get a friend to commit eating less poultry, she'll be more likely to be persuaded to go vegetarian later on. And from there, she's just a hop, skip, and a jump away from veganism, donating most of her income to Vegan Outreach, and becoming an evangelist for wild animals.
However, you must make a follow-up request for this technique to be successful; don't expect people to go further on their own.
ReciprocityPeople feel compelled to reciprocate (it has something to do with evolution). If you concede some side arguments, they'll be more likely to be persuaded of your main point. Giving ground on one or two issues will also make you seem more credible.
Reciprocity is also at work in the door-in-the-face method, which consists of following a demanding request that's almost certain to be turned down with a more moderate request. So you could ask a meat-eater to go vegan. When she refuses, ask her instead to reduce the amount of poultry she eats by half.
CredibilityMaking the same claim several times over the course of the conversation causes it to be perceived as more credible.
If your intent is seen as to inform rather than persuade, you'll be more persuasive. If you emphasize that you're trying to persuade somebody, she'll activate her cognitive defenses. So avoid saying things like, "I hope I'll persuade you to stop eating animals."
BearingBe nice. Be friendly. Look happy.
Look good. Comb your hair; pop your zits. (Attractive people are more persuasive.)
Method of InquiryPhrase things as questions.
Don't use systematic logical argument. Thinkers as diverse as David Hume, Jonathan Haidt, and Dale Carnegie have observed that people rarely change their attitudes because of argument. If somebody's views are contradictory, don't point that out directly; instead ask questions that lead her to question her beliefs (like Socrates!).
Emphasize areas in which you agree.
Don't—
DON'T—present your argument in a myths—facts format. After a few days, people tend to forget which was which. Just say what
is the case. Instead of saying, "Lots of people believe that farm animals are kept in idyllic pastures, given individual names by the farmer, and sung to daily by beautiful shepherdesses, but this simply isn't the case," say, "Farmed animals are kept in execrable (EK-si-kruh-bul), despicable (
DES-pik-uh-bul), miserable (MIZ-ur-uh-bul) conditions."
Social Contagion
IS WRONG WRONG WRONGThe book contains a chapter on social contagion. The research, widely reported on in the media,
has been called into question. We do have an influence on our friends and co-workers, but it isn't magical.
If we have a choice, though, it does make sense to try to influence people who are better connected.
P.S. Mercy for Animals has a good video called "Farm to Fridge" at
