Historical Development of Social Psychology

"Nothing is more practical than a good theory." — Kurt Lewin

The history of social psychology is the history of humanity trying to understand itself — why we form societies, why we obey authority, why we help or harm strangers. This history spans from ancient philosophical debates about human nature to cutting-edge neuroscience laboratories. Understanding these origins illuminates why social psychology looks the way it does today.

1. Social Thought Before the Advent of Social Science​

Long before social psychology existed as a discipline, philosophers grappled with the fundamental question: What is the relationship between the individual and society?

Two dominant traditions emerged from ancient Greece:

The Platonic Tradition (Socio-Centred Approach)​

Platonic thought emphasised the primacy of the state over the individual. The individual's purpose was to be educated and shaped into a properly social being. Society and its structures determine who we are and what we become.

In modern terms, this became the socio-centred approach: social structures (systems, institutions, groups) determine individual experience and behaviour.

The Aristotelian Tradition (Individual-Centred Approach)​

Aristotle held that human beings are social by nature — the polis (city-state) emerges naturally from human sociability, not imposed upon it. Individuals naturally form families, then tribes, then states.

In modern terms, this became the individual-centred approach: social systems can be explained in terms of individual processes and psychological functions.

The Concept of Group Mind: Hegel​

Georg Hegel (1770–1831) introduced the notion that the state is not only the ultimate form of society but the incarnation of the objective social mind, of which individual minds are active participants. This gave rise to the concept of Group Mind — the idea that collectives have a psychological life beyond the sum of their individuals.

Individualism in Two Forms​

Two dominant strands of individualism shaped early social thought:

  • Hedonism: People act to secure and maintain pleasure and avoid pain
  • Utilitarianism: People act to achieve the greatest happiness for the greatest number

These principles echo through most modern theories of social motivation — reinforcement, cognitive dissonance reduction, social exchange theory all carry traces of hedonic and utilitarian thinking.

Power from Machiavelli and Hobbes​

The concepts of social power and influence entered social thought through Machiavelli (1513) and Hobbes (1651). Power later became a central construct in Lewin's field theory and social exchange theory — studied in aggression, conformity, and obedience to authority.

2. Stage 2: Social Psychology Emerges as a Discipline​

By the mid-19th century, three conditions were ripe for a new scientific discipline to emerge (Andreyeva, 1990):

  1. Practical need: Other sciences (linguistics, anthropology, ethnography) generated socio-psychological problems requiring specialised tools
  2. Internal development: Socio-psychological problems became recognisable within psychology and sociology
  3. First independent forms: Preliminary socio-psychological theories began to appear

Three early theoretical movements were most important:

2.1 People's Psychology (Völkerpsychologie)​

Developed in Germany in the mid-19th century by Moritz Lazarus (1824–1903) and Heymann Steinthal (1823–1893).

Their 1859 article "Introductory Thoughts on People's Psychology" (in the journal People's Psychology and Linguistics) argued that:

  • The main force of history is "the spirit of the people" (Volksgeist) — visible in art, religion, language, myths, customs
  • Individual consciousness is merely a product of this collective spirit
  • The task of social psychology: uncover the psychological essence of the people's spirit and the laws governing spiritual activity

Wilhelm Wundt (1832–1920) extended this tradition, arguing psychology has two parts:

  • Physiological psychology — experimental, for lower mental processes
  • People's psychology (Völkerpsychologie) — non-experimental, for higher mental processes (language, thinking, customs, art)

Lev Vygotsky's critique was devastating: He opposed studying "crystals of ideology" (language, myths) and instead argued for studying the mental processes themselves. He also insisted that even individual personality is social and therefore a valid object of social psychology. His cultural-historical theory of higher mental functions (attention, memory, reasoning) grounded in social conditions was a critical counterpoint.

2.2 Mass Psychology​

Developed in France in the latter half of the 19th century by:

  • Scipio Sighele (1868–1913) — Italian lawyer
  • Gustave Le Bon (1841–1931) — French sociologist

Both built on Gabriel Tarde's (1843–1904) ideas about the role of imitation and irrational movements in social behaviour.

Le Bon's core argument: When people aggregate into a crowd (mass), there is:

  • Depersonalisation — loss of individual identity
  • Predominance of emotions over intellect — rational thought collapses
  • General loss of sense of personal responsibility
  • Crowd mind is qualitatively different from — and inferior to — individual minds

While mass psychology captured something real (the irrationality of crowds had been witnessed during the French Revolution and later revolutionary events), it suffered from:

  • Lack of empirical grounding
  • Developed outside academic psychology
  • No significant methodological consequences for the field

2.3 Theory of Instincts of Social Behaviour​

Both people's psychology and mass psychology implicitly relied on instinctual explanations. This was formalised by William McDougall (1871–1938) in the first textbook era.

3. The First Textbooks: 1908 — Birth of Social Psychology as a Discipline​

1908 is celebrated as the year social psychology emerged as an independent scientific discipline. Two books with the title "Social Psychology" appeared simultaneously:

BookAuthorDisciplineKey Argument
An Introduction to Social PsychologyWilliam McDougallPsychologySocial behaviour stems from inborn instincts — imitation and suggestion rooted in biological nature
Social PsychologyEdward A. RossSociologySocial uniformities in feeling, belief, and action explained by imitation and suggestion operating collectively

James Mark Baldwin had earlier (1897) published Social and Ethical Interpretation in Mental Development in New York, considered one of the first systematic manuals.

The problem with McDougall's instinct theory: Recognising instincts as the motive force behind social behaviour gave undue importance to irrational and unconscious motives. Rational human thought processes were undervalued. Overcoming instinct theory became an important milestone in developing scientific social psychology.

4. The Beginning of Experimental Research: Early 20th Century​

The transformation of social psychology into an experimental science is one of the most important developments in the field.

Norman Triplett's 1897 Study — The First Social Psychology Experiment​

Triplett studied "the dynamogenic effects of pace-making" — comparing cyclists' speeds when racing alone vs. competing with others. He found performance improved with others present. This was the first study of social facilitation.

Floyd Allport and Walter Moede​

  • Walter Moede (Europe) and Floyd Allport (USA) conducted systematic experimental investigations
  • Allport compared performance of individuals working alone vs. before an audience or alongside others doing the same task
  • Found the social facilitation effect: the presence of others often improved performance
  • In 1924, Allport published the first social psychology textbook based on experimental research — a landmark that directed the field toward empiricism

The 1920s–1940s: Systematic Investigation​

After Allport's publication, social psychology expanded rapidly into:

  • Attitude measurement — how do we assess social attitudes scientifically?
  • Social norms — Muzafer Sherif (1935) studied how social norms emerge and their impact on behaviour
  • Aggression — Dollard, Doob & Miller (1939): the frustration-aggression hypothesis — frustration always produces instigation to aggression
  • Leadership — Kurt Lewin, Lipitt, and White (1939): styles of leadership (autocratic, democratic, laissez-faire) and group processes

Kurt Lewin: The Father of Applied Social Psychology​

Kurt Lewin (1890–1947) is arguably the most important figure in 20th-century social psychology. He:

  • Established the Research Centre for Group Dynamics at MIT (1948) — the birthplace of experimental social group research
  • Believed significant social problems could be investigated in the laboratory
  • Developed field theory — behaviour understood as resulting from the dynamic field of forces surrounding the person
  • Championed action research — using research to solve real social problems
  • Famously said: "Nothing is more practical than a good theory"

5. Social Psychology's Youth and Maturation: 1940s–1980s​

The 1940s–1960s: Revolution Toward Cognitive Psychology​

A major shift occurred: social psychology moved from viewing behaviour as driven by instincts to seeing it as thoughtful, purposive, and cognitively mediated.

Key developments:

  • Solomon Asch (1956, 1958): Classic conformity studies — showed how powerfully social pressure shapes judgements, even against obvious evidence
  • Leon Festinger (1950, 1954, 1957): Cognitive dissonance theory — people are motivated to maintain consistency between their beliefs and behaviours; inconsistency creates psychological tension
  • Attribution theory: Fritz Heider, Harold Kelley, and E. E. Jones studied how people explain the causes of others' (and their own) behaviour

The 1970s–1980s: Expanding Application​

Rapid social change accelerated the scope of social psychology:

  • Attribution theory — inferring causes of others' behaviours
  • Gender differences — systematic study of how gender shapes social experience
  • Environmental psychology — how physical environments (crowding, noise, temperature) affect social behaviour
  • Applications — personal health, legal processes, work settings, education

Middle Range Theories​

Robert Merton's concept of middle range theories — focused, testable theories about specific social phenomena rather than grand unified theories — became the dominant model for social psychological theorising.

Examples of middle range theories:

  • Frustration-aggression theory
  • Cognitive dissonance theory
  • Social exchange theory
  • Attribution theory
  • Social identity theory

These theories cluster around four major psychological traditions:

TraditionView of the IndividualSocial Psychology Contribution
PsychoanalyticHomo valence — the striving man; product of unconscious drivesPersonality development, socialisation, aggression, family interaction
CognitiveHomo Sapiens — the thinking man; society represented in experienceAttitudes, values, language, group dynamics, action research
BehaviouristicHomo Mechanicus — the reactive man; society = stimuli and reinforcersSocialisation, social reward and punishment, experimental methodology
InteractionistThe social self — shaped through symbolic interactionRole theory, reference group theory, social determinants of behaviour

Two trends from the 1990s continued and intensified:

  1. Growing influence of cognitive perspective — Social cognition, implicit attitudes, dual-process theories
  2. Increasing interest in application — Real-world problems demand social psychological expertise

Additional contemporary trends:

Evolutionary Social Psychology​

Applies Darwinian principles to explain social behaviour — why do we cooperate, compete, form pair bonds, exhibit altruism? Mechanisms evolved because they were adaptive for our ancestors.

Neurocognitive Perspective​

Social neuroscience — studying the neural underpinnings of social behaviour using fMRI, EEG, and related technologies. How does the brain process social information? What happens neurologically during prejudice, empathy, or social exclusion?

Technology and Human Social Behaviour​

How does social media, smartphones, and digital connectivity reshape social influence, identity formation, relationships, and political behaviour?

Multicultural Perspective​

Growing recognition that most social psychology research was conducted on Western, Educated, Industrial, Rich, Democratic (WEIRD) samples. Cross-cultural and multicultural research examines universal versus culturally-specific social behaviours.
