Envy coupled with competition divides society into an upper and lower class, game theoretical study shows -- ScienceDaily

Game theory provides the mathematical tools necessary for the modelling of decision situations with several participants, as in Gros' study. In general, constellations in which the decision strategies of the individual actors mutually influence each other are particularly revealing. The success of the individual depends then not only on his or her own actions, but on others' actions as well, which is typical of both economic and social contexts. Game theory is consequently firmly anchored in the economy. The stability condition of game theory, the "Nash equilibrium," is a concept developed by John Forbes Nash in his dissertation in 1950, using the example of poker players. It states that in equilibrium no player has anything to gain by changing their strategy if the other players do not change theirs either. An individual only tries out new behaviour patterns if there is a potential gain. Since this causal chain also applies to evolutionary processes, the evolutionary and behavioural sciences regularly fall back on game theoretical models, for example when researching animal behaviours such as the migratory flight routes of birds, or their competition for nesting sites. Even in an envy-induced class society there is no incentive for an individual to change his or her strategy, according to Gros. It is therefore Nash stable. In the divided envy society there is a marked difference in income between the upper and lower class which is the same for all members of each social class. Typical for the members of the lower class is, according to Gros, that they spend their time on a series of different activities, something game theory terms a "mixed strategy." Members of the upper class, however, concentrate on a single task, i.e., they pursue a "pure strategy." It is also striking that the upper class can choose between various options while the lower class only has access to a single mixed strategy. "The upper class is therefore individualistic, while agents in the lower class are lost in the crowd, so to speak," the physicist sums up.

Yale study shows class bias in hiring based on few seconds of speech | YaleNews

The researchers based their findings on five separate studies. The first four examined the extent that people accurately perceive social class based on a few seconds of speech. They found that reciting seven random words is sufficient to allow people to discern the speaker’s social class with above-chance accuracy. They discovered that speech adhering to subjective standards for English as well as digital standards — i.e. the voices used in tech products like the Amazon Alexa or Google Assistant — is associated with both actual and perceived higher social class. The researchers also showed that pronunciation cues in an individual’s speech communicate their social status more accurately than the content of their speech. The fifth study examined how these speech cues influence hiring. Twenty prospective job candidates from varied current and childhood socioeconomic backgrounds were recruited from the New Haven community to interview for an entry-level lab manager position at Yale. Prior to sitting for a formal job interview, the candidates each recorded a conversation in which they were asked to briefly describe themselves. A sample of 274 individuals with hiring experience either listened to the audio or read transcripts of the recordings. The hiring managers were asked to assess the candidates’ professional qualities, starting salary, signing bonus, and perceived social class based solely on the brief pre-interview discussion without reviewing the applicants’ job interview responses or resumes.   The hiring managers who listened to the audio recordings were more likely to accurately assess socioeconomic status than those who read transcripts, according to the study. Devoid of any information about the candidates’ actual qualifications, the hiring managers judged the candidates from higher social classes as more likely to be competent for the job, and a better fit for it than the applicants from lower social classes. Moreover, they assigned the applicants from higher social classes more lucrative salaries and signing bonuses than the candidates with lower social status.

People in higher social class have an exaggerated belief that they are better than others: Overconfidence can be misinterpreted by others as greater competence, perpetuating social hierarchies, study says -- ScienceDaily

Applicants were also required to complete a psychological assessment that would be used to assess their credit worthiness. Part of that included a flashcard game, a cognitive test where participants are shown an image that goes away after they press a key and is replaced by a second image. They then have to determine whether the second image matches the first. After completing 20 trials, applicants were asked to indicate how they performed in comparison with others on a scale of 1 to 100. When the researchers compared the actual scores with applicants' predictions, they found that people with more education, more income and a higher perceived social class had an exaggerated belief that they would perform better than others, compared with their lower-class counterparts. Another two investigations involving more than 1,400 online participants found a similar association between social class and overconfidence. In one, the researchers gave participants a trivia test. Those from a higher social class thought that they did better than others; however, when the researchers examined actual performance, it was not the case. For the final investigation, the researchers recruited 236 undergraduate students, had each answer a 15-item trivia quiz and asked them to predict how they fared compared with others. They also asked them to rate their social class and for their families' income and their mothers' and fathers' education levels. A week later, the students were brought back to the lab for a videotaped mock hiring interview. More than 900 judges, recruited online, each watched one of the videos and rated their impression of the applicant's competence.

Rich guys are most likely to have no idea what they’re talking about, study suggests - The Washington Post

Using a data set spanning nine predominantly English-speaking countries, researchers delineated a number of key findings. First, men are much more likely than women to master the art of hyperbole, as are the wealthy relative to the poor or middle class. North Americans, meanwhile, tend to slip into this behavior more readily than English speakers in other parts of the globe. And if there were a world championship, as a true devotee might appreciate, the title would go to Canada, data show.

The Best Activities To List On A Resume Are Classist -- Science of Us

What was bananas, however, is how that rate skewed by gender: the lower-class male got just one callback, the lower-class female five, the higher-class woman three, and the higher-class man thirteen. That means the blue-blooded James had a 16.25 callback rate, while his nearly identical siblings had a paltry 3.83 callback percentage.

Gentry investing

Investing has become the genteel occupation of our gentry, like having a country estate used to be in England. It's a class marker and a socially acceptable way for rich techies to pass their time. Gentlemen investors decide what ideas are worth pursuing, and the people pitching to them tailor their proposals accordingly. The companies that come out of this are no longer pursuing profit, or even revenue. Instead, the measure of their success is valuation—how much money they've convinced people to tell them they're worth.

Jeb Bush sums up high school

His first year at Andover, Bush re-did the ninth grade — even so, he has admitted, he barely passed. […]Andover was much harder than the private school he had been going to in Houston. He adjusted reluctantly to its rigors and pressures. He was apathetic and apolitical and smoked marijuana, as did many others around him; some, although not all, remember him as a bully. “I was a cynical little turd in a cynical school,” he once said.

Managing life versus living in the flow

People from professional white-collar backgrounds tend to want to manage things. They want to oversee and plan and organize. And their partners who come from blue-collar backgrounds, working-class backgrounds, often tend want to go with the flow more. They let things come and feel free from self-imposed constraints. An example may be with emotions. People from professional white-collar backgrounds want to manage their emotions more often, meaning they want to think about them before they express them, consider how they feel, plan how they're going to express them if they do at all, and say it in this very intellectualized manner. And their partners who come from blue-collar backgrounds who believe in going with the flow a lot more expressed their emotions as they felt them and did it in a more honest way.
A butler never offers his hand to be shaken. He never sits down in front of his boss. He never says "You're welcome" to a guest. "If you have to say anything at all,'" Ford tells us, "say 'My pleasure, 'because "You' re welcome" is very hotel." And if something is "very hotel" or "very restaurant," it's too lax for a butler. If a butler screws up, apologies should be succinct—or not made at all. Once, when Ford served at a royal banquet, a VIP female guest abruptly turned into him, forcing his hand down her blouse. He said nothing: "Who do you think would be more embarrassed if I did?"
To a striking extent, your overall life chances can be predicted not just from your parents’ status but also from your great-great-great-grandparents’. The recent study suggests that 10 percent of variation in income can be predicted based on your parents’ earnings. In contrast, my colleagues and I estimate that 50 to 60 percent of variation in overall status is determined by your lineage. The fortunes of high-status families inexorably fall, and those of low-status families rise, toward the average — what social scientists call “regression to the mean” — but the process can take 10 to 15 generations (300 to 450 years), much longer than most social scientists have estimated in the past.
Romney confirmed after the election that he called his son one morning to tell him he thought he wasn’t going to run. “I recognized that by virtue of the realities of my circumstances, there were some drawbacks to my candidacy for a lot of Republican voters,” he told Balz in January. “One, because I had a health care plan in Massachusetts that had been copied in some respects by the president, that I would be tainted by that feature. I also realized that being a person of wealth, I would be pilloried by the president as someone who, if you use the term of the day, was in the 1 percent.”
