Ravens (Corvus corax) are indifferent to the gains of conspecific recipients or human partners in experimental tasks
Open accessAbstract
Although cooperative behaviours are common in animals, the cognitive processes underpinning such behaviours are very likely to differ between species. In humans, other-regarding preferences have been proposed to sustain long-term cooperation between individuals. The extent to which such psychological capacities exist in other animals is still under investigation. Five hand-reared ravens were first tested in an experiment where they could provide food to a conspecific at no cost to themselves. We offered them two behavioural options that provided identical amounts of food to the actor and where one of the two options additionally delivered a reward to a recipient. Subsequently, we made the ravens play a no-cost cooperation game with an experimenter. The experimenter had the same options as the animals and matched the ravens' choices, making the prosocial choice the more profitable option. In both conditions, ravens were indifferent to the effects of their choices and hence failed to help conspecifics and to cooperate with the experimenter. While our negative results should be interpreted with care, overall, our findings suggest that the ravens had no understanding of the consequences of their actions for a potential recipient. This study adds to several others that have used a similar set-up and have reported negative results on other-regarding preferences in animals.

Prosocial behaviors such as other-regarding preferences and reciprocity are thought to be more common in mammals compared to other vertebrates.
“However, prosocial behaviors such as other-regarding preferences and reciprocity are thought to be more common in mammals compared to other vertebrates11, 12.”

The Introduction (page unavailable) reports evidence of other-regarding preferences in primates and says research on prosocial behaviour has largely focused on them. It does not say these behaviours are more common in mammals than in other vertebrates, or establish that comparison for reciprocity. (LLM, conf=0.82)
Experimental — accuracy not yet measuredExperiments in crows failed to reveal other-regarding preferences and reciprocity.
“Conversely, experiments in crows, birds that display high cognitive abilities10, failed to reveal other-regarding preferences and reciprocity11, 12.”

“It has been argued that human cooperation differs from cooperation in other species because it is often based on psychological mechanisms like a sense of fairness, the willingness to punish cheaters and to reward co-operators at one’s own expenses (Fehr and Gächter 2002; Fehr and Fischbacher 2003).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
