Beliefs influence how consumers think meat tastes

Personal beliefs about how farm animals are raised can shape how consumers think about the meat-eating experience.

Beliefs about how farm animals are raised can shape consumers' meat eating experience, according to findings of a new study led by Lisa Feldman Barrett, university distinguished professor of psychology at Northeastern University.

For the study, Barrett and co-author Eric Anderson, paired identical meat samples with different descriptions and then reported on participants' eating experiences. They found that meat samples paired with descriptions of animals raised in inhumane conditions looked, smelled and tasted less pleasant to study participants than meat samples paired with descriptions of animals raised on humane farms.

Participants' beliefs also influenced their perceived flavor of the meat and the amount of meat they consumed, suggesting that beliefs can actually influence eating behavior.

The findings, published Aug. 24 in the scientific journal PLOS ONE, align with an emerging body of research that shows that beliefs can influence how consumers evaluate food.

Wine, for instance, tastes better if consumers think it's expensive — even if it's really a cheap knockoff from a corner store.

"We show that what you feel very directly influences not only how you interpret what you see but also very literally what you see," said Barrett, a pioneer in the psychology of emotion and the director of the Northeastern University Interdisciplinary Affective Science Laboratory. "We call this 'affective realism' — the tendency of your feelings to influence the actual content of your perceptual experience."

The findings, she said, suggest that anyone interested in creating things — from a chef to a filmmaker to a designer — "should consider how beliefs influence the user experience."

Testing the hypothesis

Barrett and Anderson hypothesized that believing that meat came from animals that suffered would reduce the pleasantness of the eating experience as well as product consumption. The theory is based on a concept called grounded cognition, which defines beliefs as instances of conceptual knowledge that include affective and sensory neural representations. As the researchers noted in the paper, "beliefs that meat came from animals that suffered would be represented, in part, in regions of the brain that are associated with embodied simulation of animals' experience."

To test their hypothesis, the researchers designed three different experiments. For the first experiment, study participants were asked to consume two identical samples of organic beef jerky, each of which was paired with a different label describing a different kind of farm on which cows were raised. The "humane farm" label described a farm where animals lived freely, grazing outdoors. The "factory farm" label described a farm where animals were more like prisoners, confined to indoor pens.

The researchers found that study participants ranked the "factory farm" meat sample as less pleasant along all measured consumption categories, including appearance, smell, taste and overall enjoyment. Participants were willing to pay 22% less for a 6 oz. package of the factory farm jerky compared to the "humane farm" jerky and consumed 8% less as well, showing "that implicit consumption behavior was also influenced by beliefs," the researchers wrote.

The second experiment was similar to the first, with a few key differences. This time, each study participant sampled only one of four identical roast beef samples, each of which was paired with a newly created description. To test whether the factory farm label reduced enjoyment or the humane farm label increased enjoyment, they added a control description that did not mention how the animals were raised. They also revised the original factory farm and humane farm descriptions to focus on their differences with respect to animal welfare and added a so-called factory farm+ description that highlighted the advantages of factory farming to test whether it would offset the effects of animal suffering.

The results showed that positioning factory farms in a positive light did not increase participants' enjoyment of the sample, as meat paired with the factory farm+ description was not more well liked than the meat paired with the general factory farm description. This experiment's other big finding — beef paired with the humane farm description and the control description were equally liked — suggests that the humane farm description did not increase liking but, rather, that the factory farm description reduced liking.

"We were largely hypothesizing that labeling something as raised on a humane farm would improve taste and appearance and other characteristics of the meat sample, but what we found, instead, is that explicitly labeling something as factory farmed harms the perceptual qualities of the food," Barrett said.

The third experiment tested whether beliefs about how animals are raised can influence basic sensory properties of flavor, including perceived saltiness and sweetness. For this experiment, study participants were asked to consume three identical slices of thickly cut deli ham. First, they tasted ham that was paired with no description — the control condition; then, in random order, they sampled ham paired with the factory farm description and the humane farm description, both of which were revised to include evocative text and pictures of the animals.

The researchers found that the descriptions influenced the flavor ratings of the ham sample. In particular, participants reported that the factory farm ham tasted saltier, greasier and less fresh than humanely raised ham, reinforcing the study's underlying premise that experience is shaped by beliefs.

"Beliefs are really powerful. Words are really powerful. They influence what you do, often in surprising ways," Barrett said.
