What is a common caveat when generalising animal study results to humans?

• A. Species differences may limit applicability to humans
• B. Animal study results generalize perfectly to humans
• C. Animals are not suitable for any behavioural research
• D. Human behaviour is identical to animal behaviour in key aspects

Answer: (A)

When we look at how findings from animal studies can apply to humans, the key idea is about external validity across species. Animals and humans share some basic mechanisms, but there are important differences in physiology, brain structure, cognition, lifespan, and how environments shape behavior. These species differences mean that results observed in animals may not translate perfectly to humans, so researchers must be cautious about broad generalisations and often seek corroboration from human studies or multiple methods. That’s why the best choice is the one that highlights species differences as a limitation to applying animal findings to humans. Saying that generalisation is perfect ignores real biological and cognitive gaps, and claiming animals aren’t suitable for any behavioral research is overstating their value. Likewise, asserting that human behavior is identical to animal behavior is simply inaccurate, since there are notable differences despite shared foundations.
