Book summary “Cross-Cultural Psychology”: summary

Introduction

You often assume that human thoughts, feelings, and actions are essentially the same everywhere. However, your daily habits, beliefs, and emotions are profoundly shaped by the invisible cultural contexts that surround you. When you interact with people from different backgrounds, misunderstandings arise because cultural norms dictate what is considered normal, intelligent, or healthy.

Cross-cultural psychology examines how cultural norms and environmental conditions shape human behavior, cognition, and emotion through critical comparative analysis.

Eric B. Shiraev provides a comprehensive map of this scientific discipline. You will explore critical thinking tools, research methods, and the complex links between culture and perception, intelligence, emotion, motivation, and human development. The book also addresses psychological disorders and applied social issues.

As you read, you will find answers to several core questions:

• How do cultural norms influence basic cognitive processes and emotions?
• What methods do psychologists use to study human behavior across different cultures without bias?
• Why do definitions of intelligence and mental health vary across the globe?
• How do socialization and parenting shape your worldview and values?

1. Understanding Cross-Cultural Psychology

Cross-cultural psychology investigates the systematic links between cultural norms and psychological diversity, balancing the search for universal traits with the study of cultural specifics.

Cross-cultural psychology is defined as the critical and comparative study of cultural effects on human psychology. You need at least two samples representing two different groups to conduct this research. The field examines psychological diversity and the underlying reasons for such diversity. It also establishes psychological universals common across cultures through the similarity-uniqueness paradox.

Psychological knowledge is classified into four distinct categories:

• scientific knowledge;
• folk theories;
• value-based ideological knowledge;
• legal knowledge.

Scientific knowledge relies on systematic observation and testing. Folk theories encompass popular beliefs and everyday assumptions. Ideological knowledge stems from stable worldview perceptions without empirical scrutiny. Legal knowledge consists of formal prescriptions established by authorities.

The Hua people in New Guinea hold a folk belief that food carries the essence and social status of the person who prepares it.

Cultural Polarities and Approaches

Cultures are broadly divided into traditional constructs and nontraditional constructs. Traditional cultures depend on past rules and regional boundaries. Nontraditional cultures are driven by science, technology, and social innovations.

In traditional Chinese culture, women's roles were defined primarily through familial obedience to their father, husband, and son.

Cultural differences are frequently conceptualized using polarities such as power distance, uncertainty orientation, and individualism versus collectivism. Power distance measures acceptance of unequal power distribution. Uncertainty orientation measures how people handle ambiguity. Individualism emphasizes personal independence, whereas collectivism focuses on interdependence and group responsibilities.

Thomas Talhelm and colleagues demonstrated that historical agricultural differences between wheat farming in the West and rice farming in the East explain large-scale psychological differences in collectivism within China. A study of 135 nations found that low uncertainty avoidance scores correlate with helping behavior. Another study of 36 countries linked collectivism to trust within a limited group and individualism to trust across a wider selection of people.

The study of cross-cultural psychology draws upon six primary approaches:

• natural sciences;
• social sciences;
• humanities;
• ecocultural;
• cultural mixtures;
• an integrative framework.

These approaches integrate biology, evolutionary theory, neuroscience, anthropology, sociology, economics, artistic expression, ecological context, and dynamic global interactions to explain human behavior. Kitayama and colleagues found that people in Hokkaido, a northern Japanese island with a history of frontier settlement, exhibited a greater degree of American-style individualism than mainland Japanese people.

Multiculturalism promotes equal recognition and rights for all ethnic and religious groups to maintain their own identities. Ethnocentrism involves judging other cultures through the preconceptions of your own group. In a classic study, college students asked to draw a world map in ten minutes almost universally drew their own country as disproportionately large.

2. Critical Thinking in Cross-Cultural Psychology

Cognitive biases, evaluative language, and pervasive heuristics distort human judgment, requiring rigorous metathoughts to evaluate psychological phenomena objectively.

Language used to describe human behavior is rarely neutral and almost always carries subjective value judgments. You lack entirely neutral adjectives when describing people or groups. Traits like reckless are described as brave, and narcissistic as high self-esteem.

• Remember that descriptions, especially concerning personality characteristics, can never be entirely objective, impartial, or neutral.
• Become aware of your own personal values and biases and how these influence the language that you use.
• Avoid presenting your value judgments as objective reflections of truth.
• Recognize how other people’s use of language reveals their own values and biases.

You frequently make the mistake of treating continuous variables as if they were dichotomous variables. Most person-related phenomena are continuous but are incorrectly forced into discrete binary categories. Flipping a coin is a dichotomous variable, whereas introversion versus extraversion is a continuous variable.

• Learn to differentiate between variables that are dichotomous and those that are continuous.
• Remember that most person-related phenomena – such as traits, attitudes, and beliefs – lie along a continuum.
• When making cross-cultural comparisons, try to avoid artificial or false dichotomies.

Common Cognitive Biases

You possess an assimilation bias that leads you to distort new data to fit pre-existing schemas rather than modifying your schemas. A medical school interviewer used criteria like neurotic for divorced female applicants and immature for single applicants to maintain biased schemas.

• Do not underestimate the extent to which your prior beliefs, knowledge, and expectancies can affect your current experience, impressions, and perceptions.
• Try to become as aware as possible of schemas that are important to you.
• Experiment with temporarily lowering or altering your perceptual filters.
• Learn to differentiate your use of assimilation versus accommodation.
• Prod yourself to accommodate when you would typically be inclined to automatically assimilate.

You rely on the representativeness heuristic to judge whether an instance belongs to a category by comparing it to a mental prototype, often ignoring statistical base rates. Daniel Kahneman won the Nobel Prize in economics in 2002 for explaining how people make economic and business decisions using heuristics.

• Make a conscious effort to consider the possibility that the prototype in question might be inaccurate, biased, or incomplete.
• Take into account relevant statistical information, such as base rates, sample sizes, and chance probability.
• Beware of the natural tendency to overestimate the degree of similarity between phenomena and categories.

Causation and Fallacies

A correlation between two variables establishes a relationship for prediction but does not prove causation. Exposure to violent media is mildly correlated with aggressive behavior, but this does not prove media violence causes aggressiveness.

• Remember that a correlation or co-appearance is not, in itself, proof of causation.
• Keep in mind that correlations enable us to make predictions from one event to another; they do not provide explanations as to why.
• When a correlation is observed, consider all possible pathways and directions of causation.

The naturalistic fallacy occurs when people mistakenly equate the statistical frequency of a behavior with its moral value or equate what is with what ought to be. Historical justifications for colonization and slavery relied on the assumption that different cultural practices were inherently inferior or wrong, 250 years after David Hume pointed out the separation of values from logic.

• Do not make the mistake of equating statistical frequency with moral value.
• Learn to differentiate objective descriptions from subjective prescriptions.

3. Methodology of Cross-Cultural Research

Conducting valid cross-cultural research demands rigorous sampling, precise measurement, careful translation, and an integration of quantitative and qualitative strategies.

Research Goals and Sample Selection

Cross-cultural research pursues four primary goals: describing facts, explaining similarities and differences, predicting outcomes, and managing or applying findings practically. Researchers choose an application-oriented strategy or a comparativist strategy. Sample selection relies on availability sampling, systematic sampling, or random sampling to achieve a representative sample.

David Schmitt and colleagues measured personality traits across 17,837 individuals from 56 nations using random sampling.

Data Collection and Comparative Frameworks

Observation and surveys are primary data collection techniques in cross-cultural psychology. Researchers balance the absolutist approach, which assumes psychological phenomena are identical across cultures, with the relativist approach, which asserts behavior must be understood within its cultural context. Most modern psychologists adopt an integrative perspective combining etic and emic viewpoints.

Kassinove et al. (1997) used a meticulous translation and back-translation process involving a Russian psychologist and psychiatrist to adapt the State-Trait Anger Expression Inventory into Russian.

You must follow rigorous steps when conducting research:

• Step 1. Describe a problem (an issue) you decide to study. Review the scholarly literature on the topic.
• Step 2. Identify your research goal. Then, introduce one or several hypotheses for your study.
• Step 3. Identify and describe the research sample of your study.
• Step 4. Choose or design a methodology for your project, ensuring it does not violate research ethics.
• Step 5. Conduct a pilot study.
• Step 6. Collect research data.
• Step 7. Interpret your data using statistical or other procedures.
• Step 8. Critically analyze the results in a report.
• Step 9. Suggest where and how your data should be or could be used.

4. Cognition, Perception, and States of Consciousness

Sensation converts external physical energy into neurophysiological signals. Perception organizes these sensations into meaningful patterns. When sensation and perception were first studied in psychological laboratories in several countries 130 years ago, researchers noticed distinct differences between physiological input and psychological interpretation.

While basic sensory mechanisms are universal, cultural environments, perceptual sets, and temporal frameworks profoundly shape human perception and altered states of consciousness.

A French adult immediately recognizes a blue, white, and red vertical stripe sequence as their national flag. A child from Bangladesh sees it as just colored stripes. Perceptual expectations, known as a perceptual set, increase the speed and efficiency of the perceptual process. Individuals under physical deprivation tend to perceive need-related stimuli at shorter exposure times. In a study by Bruner and Goodman, children from poor families overestimated the size of coins compared to wealthier children.

Susceptibility to visual geometric illusions varies culturally. This is explained by the carpentered world hypothesis, which posits that people raised in environments shaped by rectangular structures interpret figures differently. Western samples living in industrial and urban environments are generally more prone to illusions like the Müller-Lyer, Ponzo, and horizontal-vertical illusions than non-Western or open-landscape samples. Sand foragers of the Kalahari region in Southern Africa were more likely to see the lines in the Müller-Lyer illusion as equal in length rather than differing.

Sensation and Perceptual Illusions

Writing direction and language habits systematically influence spatial motor behaviors. More than 80 percent of people raised in the US drew circles counterclockwise, while in Japan 80 percent used a clockwise motion. Color perception also interacts with language categories. During a 1993 economic recession, 42 percent of Russians associated their lives with gray, and 21 percent associated their lives with black.

Time, Dreams, and Consciousness

Cultures differ fundamentally in how they conceptualize and manage time, dividing broadly into monochronic systems and polychronic systems. Cultures also adopt fundamentally different views on dreams, categorized into monophasic cultures and polyphasic cultures. Polyphasic cultures treat dreams as flights of the soul or direct communications from ancestors. The Iroquois view dreams as real events representing soul travel that demand action regarding unfulfilled needs or future events.

Altered states of consciousness, including trance, possession, meditation, and hypnosis, depend heavily on cultural context. In South Korea, professional mediators known as manshin perform possession trance techniques called musok to communicate with gods and spirits. You can practice meditation using structured mental exercises.

• Recite a mantra (a word, phrase, or sound repeated to aid concentration).
• Practice for 15-20 minutes once or twice per day while relaxing with the eyes closed.

5. Intelligence and Cognitive Styles

Intelligence refers to the mental skills and knowledge required to pursue goals, solve problems, and adapt to specific environments. More than 90 percent of undergraduate psychology students surveyed across an undergraduate class stated they would prefer to increase their intellectual skills.

The psychometric approach measures intelligence through standardized mental tests that yield an intelligence quotient.

The numerically average IQ score is 100. Approximately 95 percent of the population has scores within two standard deviations of 15, falling between 70 and 130. Alfred Binet and Theodore Simon originally developed tests in France to identify schoolchildren who required special education placement rather than mainstream schooling.

Standardized tests show observable differences in average intelligence scores across different ethnic, racial, and national groups. On average, African American schoolchildren score 10-15 percent lower on standardized intelligence tests than white schoolchildren, a gap that persists into adulthood. Intelligence tests often contain internal cultural biases because their vocabulary, items, and tasks favor groups familiar with those specific references. When a culturally oriented vocabulary test unique to the African American community was administered, black kids scored a mean of 87 out of 100, while white children scored a mean of 51.

Biological and Environmental Influences

Heredity and biological factors play a substantial role in human intelligence, as demonstrated by twin studies and neuroscientific research. Intelligence scores of identical twins raised either together or apart showed high correlations approaching nearly +0.90. Environmental resources, family climate, and socioeconomic status heavily influence an individual's intellectual development and test scores. According to 2022 Census data, 17 percent of U.S. children under age 18 lived in families below the official poverty level.

Culture shapes cognitive styles, leading to distinct differences in how individuals perceive, categorize, and remember information. Experimental studies showed that Chinese, South Korean, and Japanese students were more holistic in their perceptions and organized objects in a more relational and less categorical way compared to Western students. Cross-cultural borrowing can enrich innovation, but you must apply mindful practices to avoid disrespect and cultural appropriation:

• Strive for empathy toward other groups that might be affected.
• Attempt to understand the culture from which you are borrowing, which includes acknowledging its possible history of oppression and marginalization.
• Be particularly careful if the choice you are considering might promote a cultural stereotype or is considered sacred to another group.
• Consider consulting with and supporting creators from that culture.
• Try to credit the source of your inspiration, and if profit is involved, be fair in your handling of compensation.

6. Emotion and Expressivity

Basic emotions share universal physiological and recognition roots, but cultural display rules, appraisal frameworks, and social norms govern their expression and subjective meaning.

Theories and Recognition of Emotion

Human emotions involve universal physiological mechanisms and adaptive functions, yet their expression, interpretation, and labeling are heavily shaped by cultural context. Charles Darwin collected global interviews showing that basic emotional expressions serve adaptive evolutionary purposes, such as facial expressions signaling readiness to fight or flee.

Several classical psychological theories explain the sequence and interaction of physiological arousal and subjective emotional experience. The James-Lange theory posits that physical arousal leads to the subjective experience of emotion. The Cannon-Bard theory suggests life situations simultaneously elicit emotional experiences and bodily responses. The Schachter-Singer two-factor theory argues that emotional experience relies on physiological arousal followed by cognitive interpretation. William James suggested in 1884 that people do not jump and clap because they are happy, but rather become happy because they jump and clap.

People across the world can reliably identify basic human emotions and vocal intonations from different cultures, indicating a shared human recognition framework. Ekman and colleagues showed photographs displaying six emotions to subjects in the United States, Brazil, Chile, Argentina, and Japan, finding that most subjects correctly identified the emotions.

Cultural Construction and Stress

Batja Mesquita argues that emotions are not fixed internal mental states, but interpersonal and cultural constructs shaped by social norms and language. To emphasize that emotions are relational and dynamic processes occurring between individuals acting according to cultural norms, Mesquita proposes the OURS model, which stands for OUtside the person, Relational, and Situated. In Japanese, the word haji does not distinguish between embarrassment and shame, whereas Arab Bedouins use hasham to cover shame, embarrassment, shyness, and respectability.

Cultural individualism correlates with higher emotional expressivity, particularly for positive emotions, whereas collectivist cultures often emphasize emotional restraint to protect social harmony. Matsumoto and colleagues surveyed samples in 32 countries and found that individualism positively correlated with higher expressivity of emotions like happiness and surprise.

7. Motivation and Behavior

Human motivation spans biological drives, impulse gratification, psychodynamic forces, and achievement strivings that interact directly with societal sex and aggression norms.

Drives, Growth, and Learning

Drive theories explain motivation through physiological needs that create a drive state. Arousal theories suggest you actively seek to maintain optimal levels of sensory stimulation.

A multi-nation study on academic procrastination involving over 1,000 respondents from Spain, Peru, Venezuela, the UK, Australia, and the US showed that roughly half of chronic procrastinators delay tasks for arousal reasons. Nearly half of college students regularly engage in academic procrastination, while 30 percent report a chronic tendency to procrastinate.

Impulse gratification involves controlling immediate desires for future gains. In the marshmallow experiment at Stanford University conducted 50 years ago, children who waited 15 minutes for two marshmallows instead of eating one immediately achieved better grades, higher SAT scores, higher income, lower BMI, and lower rates of drug abuse later in life. Biological factors involve structures like the prefrontal cortex and ventral striatum, while external factors such as economic security, poverty, education, and family practices shape your level of impulse control. In Sweden, lower impulse control increases the likelihood of being convicted of a crime as an adult by 32 percent.

Sigmund Freud proposed the id, ego, and superego. The inborn id seeks immediate pleasure universally, while the culturally transmitted superego and mediating ego vary across societal contexts. Carl Jung criticized the ethnocentric worldview of early Western psychology and urged researchers to study folklore, myths, dreams, and cultural artifacts to understand deeper psychological complexities.

Abraham Maslow arranged innate needs in a 5 categorical levels hierarchy ranging from physiological to self-actualization. He developed his profile of healthy human beings by studying historical figures like Abraham Lincoln, Albert Einstein, and Eleanor Roosevelt, noting the occurrence of profound peak experiences. Mihaly Csíkszentmihályi described flow as complete immersion in an activity, which Western cultures often link to external events and Eastern cultures link to social harmony.

Learning theories divide motivation into intrinsic and extrinsic types. Vicarious learning occurs when you observe models and witness the consequences of their behavior. In Albert Bandura's Bobo doll experiments, children between the ages of three and six who observed adults physically and verbally attacking an inflatable doll displayed significantly more aggression toward it.

Achievement, Aggression, and Sexuality

While hunger is a biological need driven by chemistry, cultural norms regulate food preferences and eating disorders. Cross-cultural food taboos dictate that items like camel eyes, dog meat, or maggot cheese are consumed in certain regions while being viewed as revolting in others. Anorexia nervosa and bulimia are heavily influenced by societal standards and are more common among young females in developed nations, where 80 to 90 percent of individuals with eating disorders are females.

David McClelland argued that achievement motivation is learned during childhood from parents who stress excellence. He analyzed children's stories in 22 cultures and found that achievement motivation scores were highly correlated with subsequent economic growth. Furnham and colleagues conducted a cross-national project on achievement and economic growth with 12,000 participants.

Aggressive motivation arises from multiple biological, socioeconomic, and psychological causes. Males consistently exhibit higher rates of violent behavior across cultures, representing 90 percent of murders and the majority of the prison population. In the United States, men are four times more likely to be arrested for various offenses compared to women. Albert Borowitz coined the term Herostratos syndrome to describe individuals like the ancient Greek arsonist Herostratos who inflict pain on others to compensate for perceived injustice and gain notoriety.

Sexual motivation is regulated by physiology, but societal sex cultures determine acceptable behaviors. A study across 33 countries revealed universal mate preferences where both men and women ranked being kind and understanding first, while men prioritized good looks and women prioritized good earning capacity. Globally, 30 percent of women experience physical or sexual violence by an intimate partner or sexual violence from a non-partner during their lifetime. Across 30 countries, 200 million girls and women have undergone female circumcision, while in 2022, 7 percent of US adults self-identified as LGBT or non-heterosexual.

8. Human Development and Socialization

Lifespan development unfolds through universal biological stages, while socialization, parenting styles, and moral frameworks imbue individuals with specific cultural values.

Psychologists make a clear distinction between internal human development across the life span and socialization into a specific culture's values. Human development covers physical, psychological, and social behavioral changes from conception to death involving growth, decline, and modification. Socialization is the lifelong process by which an individual joins a specific culture and incorporates its values and behaviors. The Six Cultures Study of Socialization, begun in 1954 across the US, Mexico, Japan, India, the Philippines, and Uganda, initiated comprehensive comparative research.

Socialization and Parenting Styles

Amy Chua popularized the term tiger mom to describe a rigid, strict parenting style focused heavily on academic achievement and family obligation. Su Yeong Kim analyzed 444 Chinese American families across an 8 years span and found that supportive parenting led to higher GPAs and lower alienation, whereas tiger parenting increased academic pressure and depression.

Behaviors labeled as dependency in Western psychology often correspond to culturally specific concepts like amae in interdependent societies. Amae describes the tendency to merge one's self with another person to increase security, particularly in Japanese mother-child relationships, showing that universal behaviors carry different linguistic labels. Vereijken and colleagues found striking similarities between behavioral descriptors of Japanese amae and American dependency.

Psychosocial and Cognitive Stages

Erik Erikson proposed that 8 developmental stages, spanning from his 1902-94 life span, each defined by a central crisis and a corresponding virtue. Jean Piaget outlined 4 periods of cognitive growth through which children build their understanding of reality. Lawrence Kohlberg categorized moral reasoning into 6 stages ranging from fear of punishment to adherence to universal ethical principles, supported by 45 empirical studies across 27 countries examined by Snarey.

Delayed entry into adult roles in industrialized and developing societies has established a distinct life phase known as emerging adulthood, spanning from the late teens to the mid-twenties. Late adulthood brings biological and psychological changes alongside shifts in time perspective, while societal views on aging vary greatly by culture. Kazuyoshi Miura played professional soccer in Portugal at age 56, Goethe completed Faust at age 80, and Joe Biden took office at age 78.

9. Psychological Disorders and Culture

Psychological disorders combine universal central symptoms with culture-specific peripheral symptoms and syndromes, mediated by clinician biases and societal tolerance thresholds.

Universalist vs Relativist Perspectives

You can view psychopathology through two contrasting theoretical frameworks. The universalist or absolutist perspective suggests that people share similar core emotions despite cultural differences. Conversely, the relativist perspective maintains that socioeconomic and political norms determine how you display and treat psychological symptoms.

Spirit possession syndromes are considered typical within certain indigenous cultures in Africa and South America. The exact same claims in a Western nation would likely be diagnosed as schizophrenia or psychosis.

An integrative approach proposes that disorders manifest as central symptoms and peripheral symptoms. Central symptoms represent core features such as dysphoria in depression or hallucinations in schizophrenia. Peripheral symptoms vary based on learned cultural expectations.

Patients diagnosed with depression in Taiwan are less likely to report feelings of guilt compared to Canadian counterparts. They display shame, bodily pain, or behavioral disturbances instead.

Cultural Syndromes and Psychodiagnosis

Cultural syndromes represent clusters of co-occurring symptoms found within specific contexts. These syndromes do not necessarily map directly onto mainstream Western psychiatric diagnostic categories.

Specific cultural groups recognize distinct syndromes:

• amok is a sudden explosion of rage recognized in Malaysia;
• shenjing shuairuo in China resembles major depressive disorder but features prominent somatic complaints and lacks profound sadness.

Depressive variations often reflect a division between psychologizing distress in Western cultures and somaticizing distress in non-Western cultures. British patients diagnosed with depression scored high on psychological complaints, while Turkish patients showed significantly higher scores on somatic complaints like sleep disturbances, pains, and aches.

Suicide rates vary widely across the globe. Exactly 700,000 people commit suicide globally every year. Lithuania and South Korea report the world's highest suicide rates at 31 per 100,000 population, while Russia reports 20 per 100,000, the United States reports 13 per 100,000, and Canada reports 10 per 100,000.

Personality disorders represent enduring patterns of behavior deviating from cultural expectations. Their diagnosis depends heavily on a society's tolerance threshold for specific traits. A woman who wears flashy apparel and seeks constant attention might be considered a normal Broadway actress in New York City. She could be suspected of histrionic personality disorder in a conservative rural town.

Substance use disorders and attitudes toward consumption are shaped by legal policies and physiological traits. The global average stands at 6.2 liters of pure alcohol per person per year, and 50 percent of the world's alcohol is consumed in Europe. Alcohol causes 3 million deaths a year worldwide. Furthermore, 1.1 billion people regularly smoke cigarettes or tobacco globally, and 7 million people are killed each year by tobacco use.

Approximately 50 percent of Korean, Japanese, and Chinese individuals lack aldehyde dehydrogenase, an enzyme that eliminates alcohol breakdown products. This deficiency causes facial flushing and palpitations that deter heavy drinking.

Clinicians' cultural backgrounds and theoretical schemas heavily influence their diagnostic perceptions. In Li-Repac's study, white therapists viewed Chinese American clients as more depressed and inhibited compared to evaluations by Chinese American therapists. Chinese American therapists judged white clients to be more severely disturbed.

10. Social Perception and Applied Psychology

Social interaction, conformity, values, and identity are structured by cultural norms, while applied cross-cultural psychology addresses social justice, digital culture, and health.

Schwartz identified three basic societal issues that distribute human values across opposing ends of a spectrum. Values are categorized into three pairs: Conservatism versus Autonomy, Hierarchy versus Egalitarianism, and Mastery versus Harmony. These values dictate how groups handle societal problems, resource distribution, and environmental exploitation across the 40 countries included in Schwartz's study.

Fritz Heider's cognitive balance theory demonstrates that people seek psychological consistency among their attitudes, though consistency pressures vary across cultures. Balance is achieved when a person and someone they like agree, or when they and someone they dislike disagree. A young woman who adores the music of Shakira is likely to agree with her stance on global immigration policies, or else her positive attitude toward the singer may shift.

Attitudes, Values, and Group Dynamics

Conformity is a universal form of social influence influenced by cultural norms, socioeconomic status, and the availability of life choices. In Solomon Asch's classic line judgment experiments, almost 75 percent of subjects conformed at least once by responding incorrectly to match a unanimous majority. Overall, 35 percent of overall responses conformed to incorrect judgments.

Stanley Milgram's experiments at Yale University showed that regular individuals easily obey authority and administer punitive measures under psychological pressure. Countries with high power distance and authoritarian socialization tend to exhibit higher rates of obedience.

Applied Social Justice and Digital Culture

To effectively overcome gender stereotypes and bias in daily life, you can apply specific behavioral and perceptual strategies:

• Be aware: Try to monitor the extent to which your gender stereotypes can affect your current experience, impressions, and perceptions.
• Look for multiple causes: When attempting to explain gender differences, look for multiple causal factors.
• Cultivate new perceptions: The goal is to form more accurate perceptions based on facts, including sound psychological research.
