Both chimps and children found to be willing to pay to see bad players punished

An international team of researchers has found that both chimpanzees and human children are willing to pay to see the punishment of someone who has behaved badly. In their paper published in the journal Nature Human Behavior, the group describes two series of experiments they carried out, one with chimpanzees in a zoo, the other with children aged four to six in a laboratory, and what they learned from them.

Most people know that humans derive some degree of pleasure when watching the punishment of those deemed bad. In this new effort, the researchers sought to learn more about this behavior by testing it in children and comparing what they found to reactions by chimpanzees.

In the first experiment, the researchers enlisted the assistance of several adult . Each was brought alone into a room where they interacted with a human researcher. In some scenarios, the human showed kindness by offering the some food. In other scenarios, the human acted mean by not sharing a food snack. After each , another human entered the scene carrying a stick which was used to (pretend) beat the first human as the chimp watched for a few seconds. Then, both actors moved to another room where the chimp could only follow the action if he worked hard to pull back a door. The researchers found that the chimps were quite eager to see the "bad" human beaten further, as evidenced by the effort to push open the door. Conversely, they did not even try to open the door to watch the action as the "good" human received more punishment.

In the second series of experiments, the researchers enlisted the assistance of 72 children between the ages of two and six—each was asked individually to watch a show in which a puppet offered the child a favorite toy—in some scenarios, the toy was given, in others, it was withdrawn. Then, another puppet appeared and began beating the first puppet. Shortly thereafter, the action moved behind a screen. If the child wanted to continue watching what happened between the puppets, they had to offer up coveted stickers. In watching the action, the researchers found that the older children were willing to give up stickers to watch the "bad" puppet receive more abuse, but not to see the good puppets get beat more. Children younger than six, however, were willing to give up stickers in either scenario, suggesting they did not understand what was occurring.

The suggest the behavior similarities between the chimps and offers evidence of a shared trait that came about during a time before our ancestors split on the .

Abstract
When misfortune befalls another, humans may feel distress, leading to a motivation to escape. When such misfortune is perceived as justified, however, it may be experienced as rewarding and lead to motivation to witness the misfortune. We explored when in human ontogeny such a motivation emerges and whether the motivation is shared by chimpanzees. Chimpanzees and four- to six-year-old children learned through direct interaction that an agent was either prosocial or antisocial and later saw each agent's punishment. They were given the option to invest physical effort (chimpanzees) or monetary units (children) to continue watching. Chimpanzees and six-year-olds showed a preference for watching punishment of the antisocial agent. An additional control experiment in chimpanzees suggests that these results cannot be attributed to more generic factors such as scene coherence or informational value seeking. This indicates that both six-year-olds and chimpanzees have a motivation to watch deserved punishment enacted.

In an odd way it seems here in the USA the 2 major political parties are taking turns being beaten by the other sides PAC's, lobbies, and the like. The voters get to keep switching TV channels to continue watching them being beaten.

Reciprocity detection appears to be a key trait for at least two primates. It would be interesting to see whether it's present in orangutans and gorillas, too.

The definition of "bad behavior," and its mutability is key, here. It can include evaluation of "divergent" thoughts, as well. For example, given three decades of word redefinitions and retraining of acceptable vocabulary, one now easily observes the willingness to spend time and money for the satisfaction of watching it being stamped out.

I don't think the definition of "bad behavior" in either this article or the paper it discusses is sophisticated enough to introduce the kinds of arguments you make here, @Vid.

Interesting assumption that we share this primitive trait with simians since before "branching" apart from them. Does this explain why interest in pro-wrestling grows? Humanity's desires have become more primitive?

Your observation is sharply drawn, but (see article, 1st sent, 2nd par) "most people know" implies a valid generalization in prep and background for the specific experimental situation presented in the paper. Extension of that generalization (even if elliptical) seemed not unreasonable, although not exactly transparent to the general reader. Sorry about that.. @the sharp one
