Why Do We Study
Social Science?
Social science exists because human behaviour doesn’t explain itself. We study it to collect evidence about how people live together, compare that evidence across societies and time periods, and build explanations that hold up to scrutiny. This guide walks through the core purposes, the main disciplines, the research methods, and how to turn that understanding into strong academic writing β without the padding.

Social science is the systematic, evidence-based study of human behaviour and the societies humans create. It covers how people live together, how groups form and compete, how institutions are built and collapse, and how societies change over time. The “science” part matters: social scientists don’t just observe or opine β they collect data, test explanations against evidence, and revise their conclusions when the evidence demands it. That commitment to method and evidence is what separates social science from journalism, politics, or opinion.
The question “why do we study social science?” sounds simple but carries real weight. Every major policy decision β how a government responds to unemployment, how a school system is organised, how a health authority handles a pandemic β rests on assumptions about how people behave and why. Social science is the field that tests those assumptions. It doesn’t always produce tidy answers. But it produces better answers than guesswork, ideology, or anecdote.
Think about why the study of human society is harder than, say, studying rocks or chemical reactions. Rocks don’t change their behaviour because someone is studying them. People do. Societies are also shaped by history, culture, language, and power β all of which vary enormously across time and place. That complexity is precisely why a rigorous, systematic approach to studying social life is necessary, not optional.
One Source Worth Knowing: The American Sociological Association
The American Sociological Association’s “What Is Sociology?” page gives a clean, authoritative overview of social science’s goals and methods directly from a major professional body. It’s free to access and gives you a legitimate external citation for assignments that ask you to define or justify social science as a discipline. Use it as a starting point for your literature engagement, not as a substitute for it.
The Three Core Purposes: Evidence, Comparison, Explanation
Your question gets at something important. We study social science to do three things, and they build on each other in a specific order. Get the sequence wrong and the whole project collapses.
Collect Evidence
Before you can explain anything, you need data. Social scientists collect evidence through surveys, interviews, official statistics, historical records, observation, and experiments. Without evidence, you have opinion β not knowledge. The type of evidence collected determines what questions you can answer.
Compare Evidence
A single observation tells you very little. You need to compare: across societies, across time periods, across different groups within the same society. Comparison is what turns an observation into a finding. It’s how you separate patterns from coincidences.
Build Explanations
Evidence and comparison don’t explain themselves. You need theory β a systematic account of why patterns occur, what causes what, and under what conditions. Good social science theory is falsifiable: it makes predictions that can be tested against new evidence.
These three steps β collect, compare, explain β are not just a research checklist. They are the core of what social science is for. Every discipline within social science, whether sociology, economics, anthropology, or political science, follows this sequence, using different tools at each stage depending on its subject matter and research tradition.
The whole art of social science is to find patterns in human behaviour that are robust enough to survive comparison β across time, across cultures, across the full variation of human social life.
β Adapted from Γmile Durkheim, The Rules of Sociological Method (1895), the foundational text on scientific method in social scienceIt’s worth being direct about what this means for your studies. If an assignment asks you “why do we study social science?”, the answer isn’t philosophical hand-waving about understanding humanity. The answer is: because we need rigorous, comparative, evidence-based explanations for how social life works β explanations that are better than prejudice, tradition, or intuition, and that can be tested and revised as new evidence accumulates.
The Main Disciplines β and What Each One Actually Studies
Social science is not one field. It’s a family of disciplines, each with a distinct focus, a set of theoretical traditions, and a preferred methodological toolkit. Knowing which discipline you’re working in matters for choosing the right methods, citing the right literature, and framing arguments in ways your examiner will recognise.
Sociology
How society is structured, how social norms operate, class, inequality, institutions, deviance, and social change
Psychology
Individual and group mental processes, behaviour, cognition, emotion, development, and social influence
Economics
How resources are produced, distributed, and consumed; decision-making under scarcity; markets and incentives
Political Science
Governance, power, political systems, elections, public policy, international relations, and state authority
Anthropology
Human cultures, evolutionary origins, kinship systems, ritual, language, and the diversity of human social organisation
Human Geography
How people interact with physical space, urbanisation, migration, place-making, and environmental relationships
History
Past events, their causes, their consequences, and what they reveal about how human societies change and persist
Law & Criminology
Legal systems, crime, punishment, social control, justice, and the relationship between law and social order
These disciplines overlap constantly. A study of poverty might draw on sociology (class structure), economics (income distribution), political science (welfare policy), and geography (spatial inequality) simultaneously. The boundaries between disciplines are real but porous β and the most interesting social science research often happens at their intersections.
Assignment Tip: Identify Your Disciplinary Frame First
Before you start writing any social science assignment, identify which discipline’s framework you’re supposed to be using. A sociology essay on poverty looks different from an economics essay on poverty β different theories, different evidence types, different argument structures. If the assignment doesn’t specify, choose one framework and stay consistent with it. Mixing disciplinary frameworks without acknowledging you’re doing so produces confused, unfocused writing.
How Groups Form, How Institutions Develop, and Why This Matters
Two of social science’s most enduring questions are: how do people come together to form groups, and how do those groups develop the institutions β the rules, roles, organisations, and norms β that structure social life? These questions sit at the heart of why social science is worth studying. Without answers to them, we can’t explain much about the social world at all.
Why Do People Form Groups?
Groups form for practical reasons β shared resources, collective defence, cooperative production. They also form around shared identity: ethnicity, religion, class, gender, profession. Social science studies both the material and the symbolic dimensions of group formation, and what happens when groups come into conflict over resources or recognition. The key question isn’t just why groups form, but why some group identities become politically powerful while others remain dormant.
How Do Institutions Emerge and Persist?
Institutions β governments, courts, schools, markets, families, religious bodies β don’t spring fully formed from individual decisions. They develop through historical processes, shaped by power, technology, culture, and the accumulated decisions of people who often had no plan beyond solving the immediate problem in front of them. Social science studies these development processes β and why institutions that no longer serve their original purpose often persist long after they should have changed.
This matters practically. If you’re studying public health, you need to know how health institutions are organised and why people trust or distrust them. If you’re studying education, you need to know how schools as institutions reproduce social inequality even when individual teachers are well-intentioned. If you’re studying crime, you need to know how the criminal justice system as an institution shapes who gets labelled criminal and who doesn’t. Social science gives you the tools to see institutions not as neutral background but as active forces that shape outcomes.
| Institution Type | Social Science Questions It Raises | Relevant Discipline(s) |
|---|---|---|
| The State / Government | How does political authority get established and maintained? Who controls state power and who is excluded? How do states use violence to maintain order? | Political Science, Sociology, History |
| The Market | How are prices set? Why do markets produce inequality? How do markets interact with politics and culture? | Economics, Sociology of markets |
| The Family | How have family structures changed over time and why? How does family shape individual life chances? What social functions does family perform beyond reproduction? | Sociology, Anthropology, Psychology |
| Religion | What social functions does religion serve? How does religious authority relate to political authority? Why does religion persist in modernising societies? | Sociology, Anthropology, Political Science |
| Education | Does education reduce or reproduce inequality? How do schools socialise students into social norms? Who controls what counts as legitimate knowledge? | Sociology of education, Economics, Political Science |
| Law and Criminal Justice | Whose interests does law protect? How do policing and punishment relate to social class and race? What makes a legal system legitimate? | Criminology, Sociology, Political Science, Law |
Research Methods in Social Science β How Evidence Gets Collected
Method choice isn’t arbitrary. The right method depends entirely on the question you’re asking. Want to know how widespread a belief is across a population? Survey. Want to understand why individuals hold that belief and how it shapes their behaviour? Interview or ethnography. Want to test whether a policy intervention caused a specific outcome? Experiment or quasi-experimental design. Get the method wrong and your evidence won’t answer your question, no matter how carefully you collected it.
Quantitative Methods
Measuring, counting, testing patterns at scale
- Surveys and questionnaires β measuring attitudes and behaviours across large samples
- Official statistics β census data, crime data, economic indicators
- Experiments β testing cause-and-effect under controlled conditions
- Regression analysis β identifying relationships between variables
- Comparative historical analysis β testing theories across multiple cases
- Content analysis β coding and measuring text or media at scale
Qualitative Methods
Understanding meaning, context, and process in depth
- Semi-structured interviews β exploring individual perspectives and experiences in depth
- Focus groups β examining how opinions form in group discussion
- Ethnography β participant observation of social life in natural settings
- Case studies β in-depth analysis of a specific instance, event, or context
- Document analysis β interpreting texts, policies, historical records
- Discourse analysis β examining how language constructs social reality
Mixed Methods
Combining quantitative and qualitative approaches
- Sequential designs β qualitative exploration followed by quantitative testing
- Concurrent designs β collecting both types of data simultaneously
- Triangulation β using multiple methods to cross-validate findings
- Embedded designs β one method nested within a larger study of another type
- Transformative frameworks β mixed methods guided by an explicit social justice agenda
- Pragmatic approach β choosing the method that best fits the specific research question
For Assignments: Know Your Methodology Section
Many social science assignments at Level 5 and above ask you to justify your methodological choices. Don’t just describe what you did β explain why that method was appropriate for the question, what its limitations are, and how those limitations affect the conclusions you can draw. The strongest methodology sections acknowledge trade-offs rather than pretending a chosen method has no weaknesses.
Social Science vs. Natural Science β Why the Distinction Still Matters
This comes up constantly in social science study, especially at introductory level. Students are often taught that social science is “less rigorous” than natural science, or that it fails because it can’t produce the same kind of controlled experiments as chemistry or physics. That framing is wrong β but understanding why it’s wrong matters for how you frame your own work.
| Dimension | Natural Science | Social Science |
|---|---|---|
| Subject Matter | Physical and biological world β objects that do not interpret being studied | Human behaviour and social life β subjects who can reflect on, respond to, and change because of being studied |
| Experimental Control | High β laboratory conditions allow precise manipulation of variables | Low to moderate β ethical constraints and real-world complexity limit experimental control |
| Replication | Precise replication generally possible β same conditions produce same results | Context-dependency limits replication β social phenomena are embedded in specific historical and cultural conditions |
| Value Neutrality | Possible to maintain β researcher values don’t affect boiling points | Impossible to fully achieve β researchers are part of the social world they study; values affect what questions get asked |
| Prediction | High precision possible for physical systems | Probabilistic at best β human behaviour has irreducible uncertainty and reflexivity |
| Theory Type | Universal laws (gravity, thermodynamics) | Middle-range theories β generalisations that hold under specified conditions, not universal laws |
The key point is this: social science’s challenges are different from natural science’s challenges, not lesser. The reflexivity problem β that studying society changes society β is genuinely hard. The ethics of experimentation with human subjects are genuinely constraining. The context-dependency of social phenomena is genuinely limiting. Recognising these constraints isn’t an admission of failure; it’s part of what good social science methodology does.
The natural sciences tell us what the physical world must do. The social sciences can only tell us what people tend to do, under conditions that rarely hold still long enough to be measured precisely.
β Concept drawn from Max Weber’s discussion of Verstehen and the interpretive tradition in social science (Economy and Society, 1922)How to Approach Social Science Assignments β Structure, Argument, and Evidence
Social science writing is not description. It’s argument. You are making a claim, supporting it with evidence, and acknowledging what the evidence does and doesn’t show. That’s it. Every word should either advance the argument, provide evidence for it, or qualify it appropriately.

Common Mistakes in Social Science Assignments β and How to Avoid Them
| # | β Mistake | Why It Loses Marks | β The Fix |
|---|---|---|---|
| 1 | Describing instead of analysing | Restating facts about poverty, inequality, or political events without explaining why they exist or what they mean produces a report, not an essay. Examiners are not looking for a summary of what happened. | For every fact or statistic you include, follow it immediately with “which shows that⦔ or “this matters because⦔. Force yourself to articulate the analytical point the evidence is making. |
| 2 | Using personal opinion as evidence | “I think poverty is caused by⦔ or “It seems obvious that⦔ signals that you haven’t engaged with the empirical literature. Social science has evidence standards. Meet them. | Replace “I think” with “evidence suggests” or “theory X proposes, and this is supported by data showing⦔. Your interpretive judgements are welcome β but ground them in evidence from the literature, not personal intuition. |
| 3 | Treating one theory as the only theory | Writing as if Marxism, functionalism, or rational choice theory simply is correct, without acknowledging competing explanations, shows surface-level engagement with the subject. | Present the dominant theories, evaluate each against the evidence, and explain which you find most persuasive and why. Demonstrating theoretical pluralism while taking a defensible position is the hallmark of strong social science writing. |
| 4 | Ignoring context and variation | Making claims about “society” or “people” in general, without specifying which society, which time period, and which group within that society, produces unfalsifiable generalisations. | Always specify: which country or societies, which time period, which social groups. Claims that are specific are testable. Claims that are universal are usually wrong β and always harder to defend. |
| 5 | Confusing correlation with causation | Finding that two things occur together β poverty and crime, education and income β doesn’t mean one causes the other. This is perhaps the single most important methodological point in all of social science. | When describing a relationship between variables, explicitly address the causal mechanism: what is the process by which X produces Y? What confounding variables might explain the correlation without any causal relationship? Have researchers addressed these through research design? |
| 6 | Not engaging with counterarguments | An essay that only presents evidence supporting its thesis and ignores contradictory evidence reads as advocacy, not analysis. Examiners know the counterarguments β they want to see if you do too. | Explicitly address the strongest objection to your argument. Either show why the evidence for it is weaker than it appears, or acknowledge it as a genuine qualification that limits the scope of your conclusion. Engaging with objections strengthens your argument; ignoring them weakens it. |

FAQs: Why We Study Social Science
Why This Still Matters β The Practical Point
Social science isn’t abstract. Every government policy, every organisational design, every public health intervention rests on assumptions about how people behave. Social science is the field that tests those assumptions. When those assumptions are wrong β when a welfare policy assumes rational behaviour where emotional context dominates, or when a development intervention ignores local power structures β the human costs are real.
That’s the practical answer to “why do we study social science?” Not because it’s interesting (though it is). Not because it looks good on a CV (though it does). Because decisions made without understanding of social structure, group behaviour, institutional development, and social change tend to fail. And the people they fail are usually the people with the least power to absorb that failure.
The skills you develop studying social science β collecting evidence systematically, comparing across contexts, building explanations that hold up to scrutiny, arguing from evidence rather than assumption β are not just academic exercises. They are the tools for thinking clearly about how the social world works and how it could be made to work better.

How Societies Change Over Time β and How Social Science Studies Change
Social change is one of the oldest questions in social science. How do societies move from one form of organisation to another? What drives change β technology, economics, ideas, conflict, leadership? And why do some societies change rapidly while others stay stubbornly stable?
Social scientists don’t have a single theory of social change. They have several competing ones, each emphasising different drivers. That’s not a weakness β it reflects genuine uncertainty about a genuinely complex phenomenon. Your job as a student is to understand those competing theories, know what evidence supports each, and be able to evaluate them critically.
Material Conditions Drive Change
Marx argued that changes in economic organisation β in how production is organised and who controls it β are the primary engine of social change. Industrial capitalism transformed family structure, class relations, the state, and culture not because people planned it but because the material conditions of production changed. Economic analysis of social change looks at technology, labour markets, and resource distribution as the fundamental drivers.
Ideas and Values Drive Change
Weber argued that ideas β including religious ideas β could drive economic and social change, not just reflect it. The Protestant Reformation shaped the culture of capitalism, not only the other way around. Cultural theories of social change look at shifts in values, belief systems, and collective identities as independent forces that reshape how people organise their lives and institutions.
Conflict Between Groups Drives Change
Conflict theories argue that social change happens through struggle β between classes, ethnic groups, genders, or nations β over resources, rights, and recognition. Change isn’t evolutionary or inevitable; it’s the outcome of conflicts with winners and losers. Political science and conflict sociology focus on how power relations between groups determine whether and how change happens.
In practice, most social scientists draw on elements of all three. A study of apartheid’s end in South Africa might look at economic pressure (sanctions, the costs of maintaining the regime), ideas (the moral delegitimation of racial rule internationally), and conflict (the ANC’s armed struggle and mass mobilisation). No single theory is adequate. The skill is knowing when each framework is most useful and where each has explanatory limits.
What This Means for Your Essays
When an essay asks you to explain a social change β urbanisation, declining religious observance, rising inequality, the spread of democracy β don’t just describe what happened. Apply a theoretical framework: what does your chosen theory predict should have caused this change? What evidence supports that prediction? Where does the evidence not fit the theory? That structure β theory, prediction, evidence, evaluation β is the backbone of strong social science writing.
