Machiavellianism (psychology)In the field of personality psychology, Machiavellianism is a personality trait centered on manipulativeness, callousness, and indifference to morality, with a strategic focus on self interest. Psychologists Richard Christie and Florence Geis named the trait after Niccolò Machiavelli, as they used edited and truncated statements inspired by his works to study variations in human behaviors. Their Mach IV test, a 20-question, Likert-scale personality survey, became the standard self-assessment tool and scale of the Machiavellianism construct.
Henri TajfelHenri Tajfel (born Hersz Mordche; 22 June 1919 – 3 May 1982) was a Polish social psychologist, best known for his pioneering work on the cognitive aspects of prejudice and social identity theory, as well as being one of the founders of the European Association of Experimental Social Psychology. Tajfel grew up in Poland. Because of Polish numerus clausus restrictions on Jews in university education , he left Poland to study chemistry at the Sorbonne in France. At the outbreak of World War II, he volunteered to serve in the French army.
Social identity theorySocial identity is the portion of an individual's self-concept derived from perceived membership in a relevant social group. As originally formulated by social psychologists Henri Tajfel and John Turner in the 1970s and the 1980s, social identity theory introduced the concept of a social identity as a way in which to explain intergroup behaviour.
HatredHatred or hate is an intense negative emotional response towards certain people, things or ideas, usually related to opposition or revulsion toward something. Hatred is often associated with intense feelings of anger, contempt, and disgust. Hatred is sometimes seen as the opposite of love. A number of different definitions and perspectives on hatred have been put forth. Philosophers have been concerned with understanding the essence and nature of hatred, while some religions view it positively and encourage hatred toward certain outgroups.
AgeismAgeism is discrimination against individuals or groups on the basis of their age. The term was coined in 1969 by Robert Neil Butler to describe discrimination against seniors, and patterned on sexism and racism. Butler defined "ageism" as a combination of three connected elements. Originally it was identified chiefly towards older people, old age, and the aging process; discriminatory practices against older people; and institutional practices and policies that perpetuate stereotypes about elderly people.
Minority stressMinority stress describes high levels of stress faced by members of stigmatized minority groups. It may be caused by a number of factors, including poor social support and low socioeconomic status; well understood causes of minority stress are interpersonal prejudice and discrimination. Indeed, numerous scientific studies have shown that when minority individuals experience a high degree of prejudice, this can cause stress responses (e.g., high blood pressure, anxiety) that accrue over time, eventually leading to poor mental and physical health.
Ambivalent sexismAmbivalent sexism is a theoretical framework which posits that sexism has two sub-components: "hostile sexism" (HS) and "benevolent sexism" (BS). Hostile sexism reflects overtly negative evaluations and stereotypes about a gender (e.g., the ideas that women are incompetent and inferior to men). Benevolent sexism represents evaluations of gender that may appear subjectively positive (subjective to the person who is evaluating), but are actually damaging to people and gender equality more broadly (e.g.
