The ethical conundrums surrounding what humans consume in diet, media, and ideology are also encountered by teenagers. Many of these issues are socio-scientific in nature, where science supplies the facts, but personal values and beliefs ultimately shape the response.

Topics like climate change aren’t easy to debate, and parsing through them requires critical thinking, moral reasoning, and the ability to consider multiple perspectives — skills that even adults struggle with. These abilities don’t always develop naturally, and most classrooms don’t make room to practice.

Without structured practice in thinking through these kinds of problems, teenagers often default to untested intuition, peer influence, or cultural assumptions. Science class could offer the best place for students to reflect on the socio-scientific issues they’ll inherit as future decision-makers. However, many teachers feel unsure about how to guide those conversations without imposing their own values or misinforming students.

This study from Austria aimed to understand how teenagers reason through tough ethical problems and whether a structured classroom workshop changes the orientations they rely on over time. The researchers chose to have the experimental group discuss animal experimentation, a topic commonly raised in science classes that forces students to simultaneously weigh harm, benefit, and necessity.

The research team worked with 72 10th-grade students (ages 15 to 16) from Graz, Austria. They drew the students from five classes across three upper secondary schools. From each school, the researchers randomly selected one class and split it in half. One half took part in a four-hour animal ethics workshop (the experimental group), while the other half completed a similarly structured workshop on environmental issues (the comparison group). Two more classes completed surveys only, serving as the control group. A single researcher led every animal ethics session, while a biology teacher trainee led the environmental ones.

Student Workshops

Facilitators led both workshops using a structured ethical-inquiry model that encouraged students to explore competing values, hear one another’s reasoning, and articulate their own positions. The workshops ran as extracurricular sessions in the fall of 2019.

In the animal ethics workshop, students moved through three main activities:

1. Moral community exercise: Ranked eight living beings, including a human baby, human adult, fish, monkey, pig, dog, mouse, and beetle, according to how much moral concern each deserved.
2. Discussion on animal husbandry: Examined photos of companion and farmed animal housing and discussed whether the animals’ needs were being met.
3. Case studies: Read descriptions of two experiments, cancer research in mice (with moderate to severe pain) and obesity research in pigs (no expected pain), and decided whether they were acceptable.

Because Austrian biology classes don’t typically cover animal research in detail, the facilitator opened the case study segment with a short overview of why researchers use animals, relevant laws, and the basics of cost-benefit analysis.

The biology teacher trainee led the comparison group through an environmental workshop using the same time blocks and teaching model. This version focused on topics like rainforest destruction and the United Nations’ Sustainable Development Goals.

Student Surveys

To track changes in student thinking, the researchers gave all students the same questionnaire three times: one month before the workshops, immediately after, and six months later. The survey measured four ethical orientations:

• Animal rights: Humans and sentient animals deserve equal moral standing.
• Animal protection: Animal use is acceptable if they have a good life and minimal suffering.
• Anthropocentric: Human interests deserve more moral weight than animal interests.
• Lay utilitarian: Animal use is acceptable if the human benefits outweigh the animal costs.

Each orientation included three statements rated on a five-point scale from “completely disagree” to “completely agree.” Students also responded to open-ended prompts explaining and justifying their views on animal use more generally and animal experimentation in particular. Because the final survey happened during the early months of COVID-19, researchers added a number of pandemic-related questions too.

Key Results

Nearly all students placed humans at the top of their moral hierarchy — 87.5% ranked people first. They based their decisions on criteria like emotional connection, similarity to humans, perceived intelligence, and capacity to suffer. Students tended to rank dogs, monkeys, and pigs just below humans, while mice, fishes, and beetles landed much lower.

Across all groups, animal protection was the strongest ethical orientation at the outset, while lay utilitarian was the weakest, with animal rights and anthropocentric falling in between. Lay utilitarian was the only orientation that changed significantly over the course of the study, with scores increasing for students in the experimental group immediately after the animal ethics workshop before declining again somewhat six months later.

Students’ approval of animal experiments changed over time, though the changes were partial and context-dependent.

Despite initial skepticism, 92% of the experimental group approved at least one of the two experiments. Support was higher for the pig obesity study (72%) than for the mouse cancer study (56%), and many students accepted the painful mouse study when they believed the human benefit warranted it.

When explaining their decisions, 41% focused on the degree of animal suffering, while 30% emphasized the scientific importance of the research.

Social dynamics played a strong role in how teens justified their decisions. Many students changed their stance after hearing their peers and adopted their arguments. In some groups, students who were originally animal protection-oriented were prodded toward more utilitarian thinking.

Gender differences noted in other studies also surfaced: girls scored higher in animal rights thinking, while boys leaned more toward animal protection and lay utilitarian views.

Limitations

This was a small exploratory study based in three Austrian schools, so the findings may not represent how students in other regions think about animal issues.

The researchers also note several sources of potential bias. Socio-scientific discussions carry a risk of instructional influence, even when facilitators aim to remain neutral. Choosing biomedical examples with clear human benefits may have biased students toward utilitarian reasoning because human gain was so salient. Additionally, both the justification tasks in the workshop may have unintentionally promoted cost-benefit thinking.

World events outside the study may also have affected the outcomes. The media prominence of vaccine development during COVID-19 may have increased the perceived necessity of biomedical research for all students, including those in the control group.

Takeaways

The study’s findings raise a critical point for animal advocacy: the way animal issues are framed may matter just as much as the facts themselves. Education alone didn’t move students toward more protective orientations, and animal experimentation approval increased even among teens who received no workshop at all.

To support more compassionate and balanced attitudes toward animals in this age group, advocates may want to create outreach that challenges assumptions about human priority and use case studies that highlight non-human interest and the reality of animal suffering.

Moral reasoning develops over time, but the values that guide it in adulthood start with conversations we’re willing to have with teenagers today.
