This "problem game" was designed to be used exclusively for research. It contains a specially designed rule. The winners of the previous rounds have the ability to discard bad cards and even take good cards from other players. Yes, this is a very unfair advantage, but the winner is not necessarily treated this way.
Sixty percent of the winners believe that the game is fair and they often quote their "techniques" as the reason for their continued success. At the same time, only 30% of the losers think the game is fair, and most people don't believe that skills are a factor.
Then the researchers increased the unfair game mechanics, making the win-loss relationship and the unfairness of the rules more obvious. This has an interesting effect, prompting more winners to admit that the game is being manipulated.
The researchers compared the results of the card game experiment with the sociological study, and the results are the same. It can be seen that privileged people often think that this is their own hard work giving them an advantage rather than a simple rule factor. Game winners, life winners, and more or less have some behavior to convince themselves.
