Rats exhibit empathy, according to a study published on June 28, 2026, by researchers at Ruhr University Bochum. The findings, detailed in the journal Biological Reviews, reveal that these rodents demonstrate empathetic behavior through specific actions, such as freeing cagemates and sharing food.
Understanding Empathy in Rats
The research team, led by Professor Albert Newen, sought to explore the extent of empathy in rats compared to humans. In previous studies, rats have been observed freeing their fellow rats from cages before sharing food, suggesting a level of empathetic behavior. However, the researchers aimed to clarify whether this empathy mirrors human emotions.
Newen's team developed a model to better describe empathy across various animal species. They concluded that while rats do exhibit empathy, it is qualitatively different from human empathy. The study emphasizes the gradual differences in empathetic capabilities between species.
Behavioral Studies and Key Findings
The researchers analyzed behavioral observations from past studies, including a notable 2011 experiment where rats displayed empathetic actions. In this experiment, one rat freed another from a cage and then shared chocolate, highlighting the emotional connection between them.
Despite some skepticism regarding the classification of this behavior as true empathy, the study provided evidence that empathy in rats includes five dimensions: registering emotions, understanding situations, flexibility in behavior, and directing actions toward others. The researchers noted that rats are capable of registering emotions and situations moderately but struggle with understanding mental states beyond basic emotions.
Comparative Analysis of Empathy Across Species
The research team compared empathy profiles across various animal species, including great apes, dogs, and corvids. They found that rats possess moderate abilities in recognizing emotions and situations, with a strong capacity for flexible behavior. However, their ability to understand others' mental states remains limited.
Newen remarked, "Put simply, one can say that rats' remarkable helping behavior is a case of empathy, but it is not the same type of empathy as seen in humans." This nuanced understanding of animal empathy helps clarify the differences in emotional capacities across species.
Conclusion
This research provides a more detailed understanding of empathy in animals, particularly rats. The study challenges the notion that empathy is solely a human trait, revealing a complex landscape of emotional capabilities among different species.
