Why Adolescents May Be More Speciesist Than Adults

Most adults say they care deeply about animals. Yet, many continue to consume meat regularly — a contradiction known as the meat paradox. Interestingly, this paradox doesn’t emerge overnight. It begins to take shape during adolescence, a critical developmental stage when moral values, social norms, and personal identity start to collide.

Recent research from the UK sheds light on how adolescents, compared to adults, may actually hold more speciesist views — assigning greater moral worth to humans over other animals. This shift in perception has profound implications for how society treats farmed animals and how future generations may shape food systems.


Adolescence: A Crucial Crossroads for Moral Development

Moral beliefs aren’t static. They evolve through culture, education, peer influence, and personal experience. Adolescence is a particularly sensitive period where young people begin to reconcile the values taught in childhood with the expectations of adult society.

In the study, researchers compared 89 adolescents (ages 10–17) with 113 adults, examining:

  • Levels of speciesism
  • Views on the treatment of farmed animals
  • Moral evaluations of meat-eating
  • Perceptions of how society categorizes animals

The results were striking: adolescents were significantly more speciesist than adults. They were more likely to believe that humans have higher moral worth than other species and less likely to say pigs — used as a stand-in for farmed animals — should be treated well.


Speciesism: A Coping Mechanism for Meat-Normative Culture?

Speciesism is the belief that some species deserve more moral consideration than others. It’s the reason why many people feel comfortable testing drugs on animals but not on humans, or why dogs are cherished as companions while pigs are raised for slaughter.

The study suggests that adolescents may adopt speciesist views as a way to resolve the internal conflict between caring for animals and participating in a meat-based culture. As they learn more about food systems — including the harsh realities of industrial farming — they may increase speciesism to justify their dietary choices and align with societal norms.

This psychological strategy helps reduce cognitive dissonance: the discomfort of holding conflicting beliefs, such as loving animals but eating them.


The Role of Justifications: Natural, Necessary, and Normal

When asked why eating animals is acceptable, both adolescents and adults leaned on familiar justifications:

  • Natural: “Humans have always eaten meat.”
  • Necessary: “We need meat for nutrition.”
  • Normal: “Everyone does it.”

Adults were more likely to invoke ideas like “humane slaughter” or appeal to social norms. Adolescents, meanwhile, showed signs of having already internalized these adult rationalizations, even if they hadn’t fully embraced them.

Interestingly, adolescents were less likely than adults to say that society categorizes farmed animals as food. This may reflect lingering childhood views, where animals are seen more as companions than commodities.


Implications for Nutrition and Animal Advocacy

Understanding the moral reasoning of adolescents is essential for shaping future food systems. If adolescence is the point where speciesist attitudes solidify, then interventions aimed at promoting animal welfare and ethical eating would need to start early.

Nutrition education that includes ethical considerations — such as the environmental impact of meat production, the conditions of farmed animals, and plant-based alternatives — could help adolescents make more informed and compassionate choices.

Moreover, exposing young people to the realities of food systems without overwhelming them may encourage critical thinking rather than defensive rationalization.


Limitations and Considerations

While the study offers valuable insights, it’s important to note its limitations. The sample was predominantly white and British, and lacked socioeconomic diversity. Cultural and economic factors can significantly influence moral reasoning and dietary habits, so broader studies are needed to confirm these findings globally.

Still, the research highlights adolescence as a pivotal moment in the development of speciesist attitudes — and a prime opportunity for change.


Rethinking How We Talk to Adolescents About Animals

If we want to build a more compassionate food system, we must start by engaging adolescents in honest, age-appropriate conversations about animals, ethics, and nutrition. Here’s how we can help:

  • Educators: Integrate ethical discussions into biology and nutrition curricula.
  • Parents: Encourage open dialogue about food choices and animal welfare.
  • Advocates: Create youth-focused campaigns that highlight the lives of farmed animals.
  • Policy Makers: Support educational programs that promote critical thinking about food systems.

By addressing speciesism early, we can help the next generation make choices that align with their values — not just the norms they inherit.

  1. A really interesting Post, Cristiana. It’s interesting to understand how our moral and ethical values are shaped so much at adolescence.

  2. Great and important info as usual on what can be a tricky subject. Thanks Cristiana! If humanity took an honest look in the mirror, I think it would be hard to become a speciesist.
