1 Imagine that you and your friends have just arrived at a popular restaurant. Unfortunately, you are told by the hostess that you’ll need to wait in line for about 30 minutes to get a table because there are many other customers who had arrived before you. After about 10 minutes, a man and woman arrive and talk to the hostess. You notice that he secretly hands her some money. Immediately, she takes them to a table. Most of us would feel that this was unfair and will feel resentful toward the hostess.
2 Some researchers have recently become interested in finding out if the idea of unfairness is a unique emotion only felt by people or is it also experienced by animals. A study looked at how dogs react when a second dog is rewarded in an unequal way for doing the same trick. The researchers shook hands with two dogs, and the dogs were happy to do that whether they got a reward or not.
3 Next, they asked the dogs to “shake hands” and gave one a reward of a tasty sausage, and the other one a dull piece of bread when they did. Interestingly, the dogs didn’t seem to notice the difference and continued to follow the command and shook hands even though one got a tastier reward than the other. (See complete article below.)
