Why Is Eating Insects Disgusting? How to Change People’s Attitudes


Haidt et al. , 1997 and many other researchers said that people are animals, animal waste, items that resemble one of them, and the last one touched the former. Other incentives that make you feel aversion are sexual deviations, physical violations, poor hygiene, contact with death. The fact that I do not like something means that we have a strong inner impulse to avoid it. In terms of animals and foods, this was in part to avoid pathogens. Basically, disgust is an emotion of food refusal, but over time, bad inducers develop from many other cultural, social and moral areas (Rozin et al, 2008) .

Why do you find disgusting insects from big animals? ] Insects are often found in large groups, have 6 legs, often swaying and moving very quickly. In other words, insects can be regarded as "very resembling animals" compared to the view of larger mammals such as cattle and chickens. [Haidtetal。、1997]

Insects are bacteria and parasites, unpleasant triggers that are known to spread spoilage and disease. In addition, many insects live in the garbage, and the idea of ​​cockroaches flowing out of sewers induces disgust for most people.

The relevance to sexual deviant behavior influences why you do not like it. Insects such as medaka and flies are seen in a large flock in the summer and mating in the air.

Haidt et al. , 1997, these unpleasant events have been claimed by people to remind their animal nature (Lockwood, 2013). . People of most cultures need to be far from animals, both on physical and symbolic boundaries.

Origin of aversion and why it was beneficial

Unlike many animals who instinctively knows food, you have to learn what you omniect and eat. The advantage of being omnivorous is the flexibility and compatibility this brings, but the disadvantage is that the risk of consuming toxic ingredients increases. Omnivores always explore and research new foods, but apply scrutiny before taste. Haidt et al. (1997) have tried to clarify how disgust is developed (Haidt, Rozin, McCauley & Imada, 1997).

Reason for evolution evolution

One factor This may explain the reason for experiencing disgust in the insect's sight, and for mammals it can not be said to be related to the history of cultivation tradition. Traditionally, wild animals that "maximize profits" when cultivated on a small scale were larger mammals such as cattle, sheep, pigs and the like. Because these animals had quiet nature, they are easy to control and have a flock spirit of their flesh. Their skin may be used for clothing, tools, etc. (Terney, 2015).

This can not be said for insects. As urbanization progresses, people get less contact with nature and regularly will not be exposed to less well-known animals in natural habitats.

Second, it is surrounded by bacteria and parasites that are very similar to insects. The former is transmitted by contact with animals and waste products. In history, millions of people were killed from infectious diseases in this way, so the aversion may have evolved by natural selection. In other words, people who are sensitive to anaerobiosis have evolutionary advantages because they are less likely to be "contaminated" (Haidt et al., 1997)

social reasons for aversion

children There is a limit to the biological and evolutionary reasons of disgust because it is not born expressing a bad feeling. Not only is faeces dominant, but also during the year of toilet training that causes universal aversion, dislike develops among children. The severity of toilet training is likely to affect susceptibility to aversion, as well as the apparent aversion of parents displayed in response to diapers and other changes (Rozin, Fallon & Mandell, 1984). Interestingly, Hayst et al. , Malson (1964), found in 1997, studied 50 wild children (1965). (Children living isolated from human contacts from a very young age), it turned out that nobody felt bad feelings. Therefore, social factors may be more important than biological factors.

There are cultural differences about disgust, but they are very small compared to family situation (Rozin, Fallon & Mandell, 1984). Rozin showed that there is a small but positive correlation in food preferences between parents and their children in culture. He showed greater correlation in terms of sensitivity to anxiety and pollution. Indeed, the children showed almost the same attitudes and preferences as parents in this area

. Therefore, genetic and early environmental factors seem to play an important role in development and susceptibility to aversion (Rozin, Fallon & Mandell, 1984).

Anxiety of contamination

Trace contaminants refer to disgusting substances that come in contact with foods that are acceptable and making acceptable foods unacceptable (even if the attack target is an acceptable food short moment). This indicates that the aversion is not primarily to prevent a bad taste but rather to a more complicated way of thinking "aggressive" (Haidt et al., 1997). If we link this to the idea of ​​eating insects, people are not expecting insects' taste to be worse based on the insect's appearance, rather than worrying about "what it is" or "where was it" It is not because it is.

Small amounts of contamination are not seen in children before about 7 years of age. This happens for a certain level

Moral Element

People who are vegetarians from moral reasons feel that they dislike meat from vegetarians for health reasons . However, the process of moralization is reversible. In other words, what was previously regarded as immoral can be seen as being neutral or moral (Rozin, 1999). Conclusion

Aversion has developed as a defensive measure against the threats of the physical, social and moral world. . Disgusting like an aversion, such as animals, other people and waste products, is universal across cultures. Perhaps as a mechanism of evolutionary defense, thousands of years have caused other disgust. Why insects induce more disgusting feelings of many people over big animals and why these feelings were beneficial over time are being debated. There seems to be a biological and social reason for disgust. But the good thing is that these emotions are reversible, so in terms of eating insects it is important to know how psychologists can use this knowledge to achieve changes in human behavior and emotions A brief discussion is ongoing.


Rozin, Fallon & Mandell in 1984 is a major factor in disgust. In other words, children who observe and imitate the disgusting induced by their parents. This indicates the importance of parental behavior and child rearing style for children and should be dealt with by behavioral psychologists. Trained with the passage of time, for example, the aversion to insects changes, the idea of ​​insects' sight and eating them will no longer cause an unpleasant reaction. After changing the concept that the generation eats insects, its effect duplicates for the next generation.

Trace contamination (which makes all foods unacceptable in contact with unacceptable foods) Not about the actual taste of something, rather than about the taught, cognitive idea of ​​"discomfort" A lot of things. The fact that the effect of microbial contamination does not appear in children under 7 years of age means that the child can stop before getting it. This explains why one third of the world's population is eating insects now. They have never taught that "eating insects are" tired ". For adults, teaching insect species, breeding methods, health benefits, etc. will help overcome the fear of "what insects are" and make them look like the other sources of protein [19659002] People are very visual and most of the meat displayed on the supermarket is packed and processed, so it does not resemble the whole animal. Likewise, all insects cause the same anxiety as many people refrain by looking at the whole cow displayed as "meat". From now on, introducing people to reduce the amount of insects contained in "hidden" food items is a way to get the product to try.

Finally, the fact that even the feelings of morality are reversed is a vegetarian For moral reasons vegan can change the attitude of eating meat, and thus insects. Insects contain a lot of nutrients such as all essential amino acids and have a high protein content which many vegetarians lack. The fact that insects are under the "food chain" rather than larger animals and do not have the same cognitive level is used as a convincing argument for vegetarians and vegetarians to change the attitude of eating insects There is a possibility

a psychologist of behavior and cognition should cooperate and devise an education and training method to change the attitude of people to eat insects. 19659002]
