Canines May Not Be Reliable Representatives in Assessing Human Integrity
In a groundbreaking study conducted by researchers at Kyoto University, it has been found that dogs do not form clear reputations of humans based on observing kindness or selfishness, and this does not significantly vary with age or development[1][2][3][4].
The study, published in the journal Animal Cognition, involved 40 pet dogs of various ages. The dogs were presented with a scenario where one human was generous (feeding another dog) and another was selfish (not feeding). Despite this, when given a chance to interact with both humans, dogs showed no significant preference for the generous person — their responses did not exceed chance levels, regardless of age.
The researchers, led by Hoi-Lam Jim, suggest that reputation formation in dogs may be more complex than previously thought and that their ability to socially evaluate humans is not straightforward. They also highlight that the negative results could be due to methodological challenges, particularly the experimental design using a two-choice test, rather than an actual absence of capacity in dogs[2][3].
Regarding age and development, dogs across all ages behaved similarly, indicating that the formation of reputations of humans by dogs does not appear to vary significantly with age in the tested pet dogs[2][3][4].
For future research, the team recommends systematically studying dogs of all ages from different populations and backgrounds — including free-ranging dogs, service dogs, and police dogs — to better understand the factors influencing dogs’ sociocognitive abilities[2][3].
This study challenges the common belief that dogs naturally judge human character based on observed kindness or cruelty[1][4]. The researchers noted the dogs' behavior towards the humans, such as who they approached first, their behavior, and their proximity to each person. However, eavesdropping, or observing third-party interactions, did not lead to direct reputation formation after direct interactions in this study.
In contrast, chimpanzees can form reputations of other animals based on their own interactions or by observing third-party interactions. This ability in chimpanzees could help them avoid potential costs such as dealing with a selfish partner or aggression.
In conclusion, while dogs may not form clear reputations of humans based on observing kindness or selfishness, the study highlights the need for further research to understand the complexities of dogs' sociocognitive abilities. Dog-lovers may find comfort in the fact that their furry companions are observing their behavior, but this study suggests that their understanding and evaluation of human behavior may be more nuanced than previously thought.

- The study in Animal Cognition, led by Hoi-Lam Jim, suggests that the ability of dogs to socially evaluate humans, particularly in forming reputations, might be more complex than previously understood.
- In the realm of science, researchers recommend further investigation into the sociocognitive abilities of dogs, focusing on dogs from diverse backgrounds and populations.
- Unlike chimpanzees, who can form reputations of others based on their interactions or by observing third-party interactions, dogs, according to the study, do not form clear reputations of humans based on observing kindness or selfishness.
