Emphasize Vegetarian Retention
An underexplored way to increase the number of vegetarians
In the past twenty years, animal advocacy groups have put an enormous amount of effort into convincing people to be vegetarian. However, polls suggest that the percentage of the population that’s vegetarian has stayed basically flat since 1999. In short, we’re basically treading water: for every new vegetarian we convince, someone else quits. As you’d expect given this fact, more than four-fifths of vegans and vegetarians eventually abandon their diets.
Of course, an ex-vegetarian isn’t the same as a lifelong omnivore. They might eat less meat because they’ve discovered new favorite recipes, and they might have more knowledge of and sympathy for animal issues. (Conversely, of course, they might have been so alienated from the vegetarian and animal advocacy community that they’re more bitter and angry about it than the average omnivore.) But if we’re trying to reduce animal consumption, this is a bad sign!
Fortunately, we’re only addressing half the problem. There are lots of people trying to make people be vegetarian, but there’s far less effort put into getting them to stay vegetarian. While there are some programs along these lines, they tend (in my experience) to not be very elaborate or well-funded, particularly compared to vegan outreach. As far as I’m aware, no one has run a study of the effectiveness of various methods of keeping people vegetarian.
This is sad, because there are a priori reasons to believe that keeping people vegetarian would be easier than making them vegetarian in the first place. Vegetarians generally want to stay vegetarian, so they’re eager to listen to your information—unlike omnivores, who have to be convinced. It seems like there’s low-hanging fruit in vegetarian retention: for example, even today, many vegans don’t know about the importance of taking a B12 supplement, which means that they risk health problems that they’ll treat by going back to eating animal products.
According to a qualitative Faunalytics study, the most common reasons that people quit being vegetarian are:
Disliked/bored with food, wanted variety, wanted meat
Nutrient concerns or deficiencies (perceived or actual)
Did not enjoy it, tired of it, unsatisfied, or bored
Family, relationship, household, or children
Felt fatigued, lightheaded, weak, or unhealthy
Many of these seem potentially addressable through recommending people more delicious food, teaching them to substitute meat in their diets (for example, with alternate sources of the umami taste), teaching them more about vegetarian nutrition, and helping them to find social support. It may help to develop standard advice for common situations, such as being vegetarian while cooking for a family that is not vegetarian, and then promoting them widely. Many animal advocacy organizations are doing something along these lines to begin with, but few are doing it in a systematic way.
Vegetarian retention also seems to me to be easier to study than convincing people to become vegetarian. The hardest part of conducting a study of a method to convince people to become vegetarian is followup: how do you track down the same person you showed a video to six months later to discover whether they reduced their meat consumption? However, vegetarian retention studies can be done using the mailing lists that animal advocacy organizations already have. You’d still get attrition, of course, but the attrition is potentially much lower.
Of course, it might turn out that vegetarian retention is legitimately extremely difficult. For example, maybe only some people can be healthfully fully vegetarian for reasons we don’t understand yet, and so most prospective vegetarians will quit. But that’s also valuable to know: it suggests that we should focus on better plant-based meat alternatives, more research into nutrition science, and encouraging people who can’t handle vegetarianism to be “reducetarian.”
In short, I think more animal advocacy organizations should do randomized controlled trials of promising techniques to improve retention rates for vegetarians, so that we have a strong evidence base for this potentially effective intervention.
