3 min read

Psychologist Melanie Joy coined the term 'carnism' in 2001 to describe the invisible belief system that conditions people to eat certain animals. This ideology normalizes the consumption of meat, dairy, and eggs, while hiding the ethical contradictions from view.

Quick Summary

Carnism is the invisible belief system that rationalizes eating certain animals while showing empathy for others, using denial and justifications.

Key Points

Carnist Defined: A carnist is an individual who participates in carnism, the invisible belief system that conditions people to consume certain animals while showing empathy for others.
Ideology, Not Instinct: Carnism is not a biological necessity but a socially constructed and culturally transmitted ideology, the opposite of veganism.
Three Ns of Justification: This belief system is maintained through justifications that frame meat-eating as normal, natural, and necessary.
Psychological Defenses: Carnism relies on denial, objectification, and dichotomization to manage the cognitive dissonance of harming animals while caring about them.
Societal Invisibility: The system is so widespread that its principles are seen as common sense, making its bias largely unseen and unquestioned.
Broader Implications: Carnism, rooted in speciesism, has links to other oppressive systems and contributes to environmental degradation.

What is a Carnist? A Deeper Look

A carnist is an individual who participates in the ideology of carnism, a term coined by social psychologist Melanie Joy. Carnism is a dominant, invisible belief system that dictates which animals are considered acceptable to eat. Unlike veganism, which is seen as a choice, carnism is often the unquestioned societal default. It is a system that allows people to suppress their natural empathy for certain animals while caring for others, such as pets. Carnism achieves this by employing psychological mechanisms that conceal the reality of animal agriculture and justify the consumption of animal products.

The Three Ns of Justification

Carnism relies on rationalizations, known as the "Three Ns," to maintain the belief that eating animals is acceptable. These justifications are presented as inherent truths:

Normal: The idea that eating animals is normal because it is a widespread historical and current practice.
Natural: The belief that humans are biologically meant to eat meat, despite evidence of thriving on plant-based diets.
Necessary: The assertion that animal products are essential for health and survival, a claim often contradicted by nutrition science.

Psychological Defense Mechanisms

To reconcile the conflict between caring about animals and eating them, carnism utilizes several psychological defenses:

Denial: Avoiding the truth of animal suffering in agriculture.
Objectification: Treating animals as things rather than sentient beings, using terms like 'pork' instead of 'pig'.
Deindividualization: Viewing animals as a collective without recognizing their individual personalities.
Dichotomization: Creating categories like 'pets' and 'food animals' to enable selective empathy.
Avoiding Information: Ignoring or suppressing facts that challenge the carnistic viewpoint.

Carnism vs. Veganism: A Comparison

Understanding carnism is clarified by comparing it with veganism, often considered its opposite.


Feature	Carnism	Veganism
Core Idea	Eating certain animals is normal and necessary.	Avoiding all animal exploitation and cruelty.
Ethical Compass	Selective empathy for certain animals.	Universal empathy for all sentient beings.
Awareness	Largely unconscious societal norm.	Conscious, deliberate choice.
Justification	Relies on the "Three Ns".	Based on ethical principles.
Psychology	Uses denial, objectification, etc..	Behavior aligns with values.
Social Status	Dominant, unquestioned norm.	Often seen as alternative.

Beyond the Plate: Broader Implications

Carnism is deeply connected to speciesism, the belief in human superiority over other species. Like other systems of oppression, it employs psychological distancing to enable violence. Animal agriculture, fueled by carnism, significantly contributes to environmental issues like deforestation and greenhouse gas emissions. The normalization of meat consumption acts as a barrier to adopting more sustainable plant-based diets.

Conclusion

A carnist is an individual participating in the invisible, culturally dominant ideology of carnism, as defined by Melanie Joy. This system normalizes eating certain animals while excluding others, using psychological defenses such as denial and justification to manage the conflict between animal welfare concerns and meat consumption. Recognizing carnism is crucial for understanding our relationship with animals and the planet, encouraging more ethical and sustainable food choices that reflect values of compassion.
