Chapter 2: Research Paradigms

Dr Pauline Prevett, University of Manchester

2.1 What is a Research Paradigm?

Learning Outcomes

By completing this chapter, you will:

  • Understand what a research paradigm is and why it matters
  • Distinguish between six major research paradigms
  • Recognise how paradigms combine philosophical foundations into coherent frameworks
  • Match research questions to appropriate paradigms
  • Evaluate paradigm fit for your own research

In Chapter 1, you explored the philosophical foundations of research: ontology, epistemology, and axiology. A research paradigm is a coherent framework that combines these philosophical positions into a comprehensive worldview that guides research practice.

Think of a paradigm as a lens through which you view the research world. Different lenses bring different things into focus and blur others. No lens is inherently "better" — each reveals certain aspects of reality while concealing others.

Definition: Research Paradigm

A research paradigm is a comprehensive framework encompassing:

  • Ontology: Assumptions about the nature of reality
  • Epistemology: Assumptions about the nature of knowledge
  • Methodology: Strategies for gaining knowledge
  • Methods: Specific techniques for data collection and analysis

⚠️ Why Paradigm Choice Matters

Your choice of paradigm determines:

  • What questions you can legitimately ask
  • What counts as valid evidence
  • How you conduct your research
  • How your work will be evaluated

Paradigmatic coherence — alignment between all elements — is essential for rigorous research.

2.2 The Six Major Research Paradigms

While scholars categorise paradigms differently, six major paradigms are widely recognised in social research. Each represents a distinct way of understanding reality and knowledge.

🔬 Positivism (& Post-Positivism)

Core belief: Reality exists independently and can be studied objectively through scientific methods to discover universal laws and causal relationships.

Ontology: Single, objective reality exists independently of observers
Epistemology: Knowledge through empirical observation; researcher as objective observer
Methods: Experiments, surveys, statistical analysis, hypothesis testing

Key figures: Auguste Comte, Karl Popper (post-positivism)

Quality criteria: Validity, reliability, generalizability, replicability

🎭 Interpretivism

Core belief: Human action is meaningful. Understanding social phenomena requires grasping the subjective meanings people attach to their actions. Central concept: Verstehen (understanding).

Ontology: Reality is created through meaningful human action and interpretation
Epistemology: Knowledge through understanding subjective meaning and lived experience
Methods: Phenomenology, hermeneutics, ethnography, narrative analysis

Key figures: Max Weber, Wilhelm Dilthey, Alfred Schutz, Hans-Georg Gadamer

Quality criteria: Credibility, transferability, dependability, confirmability

🔨 Social Constructivism

Core belief: Reality is socially constructed through shared meanings, language, and social practices. Multiple realities exist because different groups construct reality differently.

Ontology: Multiple realities, constructed through social interaction
Epistemology: Knowledge is co-created between researcher and participants
Methods: Discourse analysis, participatory research, grounded theory

Key figures: Peter Berger, Thomas Luckmann, Kenneth Gergen

Quality criteria: Authenticity, credibility, reflexivity

🗿 Critical Realism

Core belief: Reality exists independently but is stratified into three domains: the empirical (experienced), the actual (events), and the real (underlying mechanisms). Research should identify causal mechanisms.

Ontology: Stratified reality with structures and mechanisms that exist independently
Epistemology: Knowledge through retroduction — inferring mechanisms from observed effects
Methods: Mixed methods, case studies, mechanism-focused analysis

Key figures: Roy Bhaskar, Margaret Archer, Andrew Sayer

Quality criteria: Explanatory power, mechanism identification, practical adequacy

⚡ Critical Theory

Core belief: Reality is shaped by power relations. Research should expose oppression and contribute to emancipation and social transformation. Knowledge is inherently political.

Ontology: Reality shaped by social, political, cultural, and economic power structures
Epistemology: Knowledge is political and value-laden; research is explicitly transformative
Methods: Participatory action research, critical discourse analysis, ideology critique

Key figures: Frankfurt School (Horkheimer, Adorno, Habermas), Paulo Freire, bell hooks

Quality criteria: Catalytic validity, democratic participation, transformative potential

🔧 Pragmatism

Core belief: Truth is determined by practical consequences. Focus on "what works" in specific contexts rather than abstract philosophical debates. Research should solve practical problems.

Ontology: Reality exists but is interpreted through human action and consequences
Epistemology: Knowledge judged by practical utility and problem-solving effectiveness
Methods: Mixed methods chosen based on research question, not paradigmatic loyalty

Key figures: Charles Sanders Peirce, William James, John Dewey

Quality criteria: Workability, utility, actionable findings

2.3 Paradigm Comparison

At a Glance

Paradigm Reality (Ontology) Knowledge (Epistemology) Typical Methods Quality Criteria
Positivism Single, objective reality Discovered through observation Experiments, surveys, statistics Validity, reliability, generalizability
Interpretivism Reality through meaningful action Understanding subjective meaning Phenomenology, hermeneutics Credibility, transferability
Constructivism Multiple, constructed realities Co-created through interaction Discourse analysis, participatory Authenticity, reflexivity
Critical Realism Stratified reality with mechanisms Retroduction to mechanisms Mixed methods, case studies Explanatory power
Critical Theory Reality shaped by power Knowledge is political PAR, critical discourse Catalytic validity
Pragmatism Reality through consequences What works in practice Problem-appropriate methods Workability, utility

Common Misconceptions

❌ Myth: "Quantitative = Positivist, Qualitative = Interpretivist"

Methods don't determine paradigm. You can use qualitative methods from a realist perspective (e.g., realist ethnography) or quantitative methods from a constructionist perspective (e.g., Q methodology).

✓ Reality

Paradigms are defined by philosophical commitments, not specific methods. Your ontological and epistemological assumptions matter more than whether you use numbers or words.

❌ Myth: "Mixed methods = Pragmatism"

Many assume that using both quantitative and qualitative methods automatically makes you a pragmatist.

✓ Reality

You can use mixed methods from any paradigm. What matters is your philosophical justification. Critical realists often use mixed methods, as do some post-positivists.

❌ Myth: "Critical theory is just political activism"

Some dismiss critical research as lacking scholarly rigour because of its explicit values.

✓ Reality

Critical theory maintains rigorous scholarly standards while being transparent about values and transformative goals. All research has values — critical theory simply makes them explicit.

2.4 Selecting a Paradigm

🧭 Quick Selection Guide

Consider what your research question is asking:

  • "What is the relationship between X and Y?" → Positivist/Post-positivist
  • "What does X mean to people?" → Interpretivist
  • "How is X socially constructed?" → Social Constructivist
  • "What mechanisms cause X?" → Critical Realist
  • "How does power shape X?" → Critical Theory
  • "What works in situation X?" → Pragmatist

Factors to Consider

1. Your Research Question

▼

Different question types lean toward different paradigms:

  • Causal/predictive questions ("Does X cause Y?") → Positivism, Critical Realism
  • Experiential questions ("How do people experience X?") → Interpretivism
  • Construction questions ("How is X understood/constructed?") → Social Constructivism
  • Power questions ("Who benefits from X?") → Critical Theory
  • Applied questions ("What works to solve X?") → Pragmatism

Remember: Your personal philosophical position and what your research question demands may differ. You must be aware of both.

2. Disciplinary Traditions

▼

Different disciplines have dominant paradigms that influence how research is evaluated:

  • Psychology, Economics: Often positivist/post-positivist
  • Sociology, Anthropology: Range from positivist to interpretivist
  • Education: All paradigms represented, often pragmatist
  • Management/Organisation Studies: Increasingly pluralist
  • Health Sciences: Moving from positivist dominance to paradigm plurality

This doesn't mean you must follow disciplinary norms, but you should understand them and be prepared to justify alternative choices.

3. Paradigmatic Coherence

▼

Your ontology, epistemology, methodology, and methods must align. Common coherence errors:

Incoherence Examples

  • Using positivist methods to study "socially constructed meaning"
  • Claiming objective neutrality while pursuing transformative goals
  • Seeking generalizable laws through single case interpretation

Coherence Check

Ask yourself: Do my beliefs about reality, my claims about knowledge, and my research practices all point in the same direction?

⚠️ No Paradigm is Superior

Each paradigm offers different insights and is suited to different research purposes. The key is choosing appropriately for your research question and maintaining internal consistency. Paradigm wars are unproductive — what matters is fitness for purpose.

🔗 Connecting Philosophy to Paradigms

Remember from Chapter 1: your ontological, epistemological, and axiological positions combine to form your paradigmatic stance. The table below shows how philosophical positions map to paradigms:

Philosophical Position Realist End Middle Ground Relativist End
Paradigms Positivism, Post-Positivism Critical Realism, Pragmatism Interpretivism, Constructivism, Critical Theory
Reality Single, objective Exists but complex/stratified Multiple, constructed
Knowledge Discovered Inferred/practical Created/interpreted

⚠️ Looking Ahead

In later chapters on research design, you'll learn how to operationalise your paradigm choice — translating philosophical commitments into practical research decisions about sampling, data collection, analysis, and quality criteria.
