December 9, 2008, here on slacktivist: Doggie justice
The researchers might have conducted a parallel study while carrying out this research. They could have hired two graduate assistants, telling each of them that they would be paid $100 at the end of each day’s research. And then, at the end of each day, they could have paid the first assistant, but not the second — not the underdog. My theory is that the underdog would quickly become “less and less inclined” to continue showing up for work.
In the case of these hypothetical assistants, of course, no one would mischaracterize the unpaid underdog’s response as “envious.” She might be angry, but she’d be refusing to cooperate not because she’s jealous of the other assistant, but because she is the victim of an injustice — because the situation is clearly unfair. Her response is not motivated by envy but by a sense of justice.
