TL;DR — Quick Answer
Research philosophy refers to the underlying beliefs and assumptions about knowledge and reality that shape how research is conducted. The main philosophies are positivism (reality is objective and measurable, favouring quantitative methods), interpretivism (reality is socially constructed and subjective, favouring qualitative methods), and pragmatism (focusing on what works to answer the research question, often supporting mixed methods). Research philosophy includes assumptions about reality (ontology) and knowledge (epistemology). It matters because it shapes the entire research approach — the questions asked, the methods used, and how findings are interpreted.
Beneath every research study lies a set of fundamental assumptions — beliefs about what reality is, what counts as knowledge, and how we can come to know things. These assumptions, often unstated, profoundly shape how research is conducted: the questions researchers ask, the methods they choose, and how they interpret their findings. This underlying foundation is research philosophy, and understanding it illuminates why research is done the way it is.
Research philosophy can seem abstract and intimidating, far removed from the practical work of research. Yet it is deeply practical in its consequences, underlying the methodological choices that shape every study. For researchers, particularly those writing theses or seeking to understand their methodology deeply, grasping research philosophy is genuinely valuable. This guide explains what research philosophy is, the main philosophical positions, and why they matter for research.
What Is Research Philosophy?
Research philosophy refers to the system of beliefs and assumptions about the nature of reality and knowledge that underlies and shapes how research is conducted. It concerns fundamental questions: What is the nature of reality? What can we know, and how can we know it? What counts as valid knowledge? The answers to these questions, whether explicit or implicit, shape the entire approach to research.
Research philosophy operates at a deep level, beneath the specific methods and techniques. It informs the researcher’s whole orientation — how they understand the phenomenon they study, what they consider valid evidence, and how they approach gaining knowledge. Different philosophical positions lead to different research approaches, methods, and interpretations.
While research philosophy may seem abstract, it has concrete consequences. The philosophical assumptions a researcher holds shape whether they pursue quantitative or qualitative research, what kinds of questions they ask, and how they interpret their findings. Understanding research philosophy reveals the foundations on which methodological choices rest.
Ontology and Epistemology
Two key concepts underlie research philosophy: ontology and epistemology.
Ontology concerns the nature of reality — what exists and what the nature of that existence is. Ontological assumptions address questions like: Is there an objective reality independent of our perceptions, or is reality socially constructed and subjective? Different ontological positions hold different views about the nature of reality.
Epistemology concerns the nature of knowledge — what knowledge is, what counts as valid knowledge, and how we can acquire it. Epistemological assumptions address questions like: Can we objectively know reality, or is knowledge always interpretive and subjective? How can valid knowledge be obtained?
These two sets of assumptions — about reality (ontology) and knowledge (epistemology) — form the foundation of research philosophy. Different research philosophies hold different ontological and epistemological positions, which shape their whole approach to research.
The Main Research Philosophies
Positivism
Positivism holds that reality is objective, measurable, and independent of the observer, and that valid knowledge is gained through objective observation and measurement. Positivists seek to discover general laws and relationships through systematic, objective methods, much like the natural sciences.
Positivism is associated with quantitative research, hypothesis testing, statistical analysis, and the search for objective, generalisable findings. A positivist researcher views the world as something that can be objectively measured and studied to uncover general patterns and causal relationships.
Interpretivism
Interpretivism holds that reality is socially constructed, subjective, and shaped by human experience and meaning, and that knowledge is gained through understanding people’s interpretations and experiences. Interpretivists seek to understand phenomena from the perspectives of those involved, recognising that human experience cannot be studied in the same way as the natural world.
Interpretivism is associated with qualitative research, in-depth understanding, and the exploration of meanings and experiences. An interpretivist researcher views reality as constructed through human meaning, and seeks to understand it through people’s subjective experiences and interpretations.
Pragmatism
Pragmatism focuses on what works to answer the research question, rather than committing to a single view of reality and knowledge. Pragmatists adopt whatever methods and approaches best address the research question, often combining quantitative and qualitative methods in mixed-methods research.
Pragmatism is associated with practical, problem-focused research and mixed methods. A pragmatist researcher is less concerned with philosophical debates about the nature of reality and more focused on choosing the approaches that effectively answer the research question.
| Philosophy | View of Reality | Associated Methods |
|---|---|---|
| Positivism | Objective, measurable | Quantitative |
| Interpretivism | Socially constructed, subjective | Qualitative |
| Pragmatism | What works for the question | Mixed methods |
Other philosophical positions exist too, such as realism (which holds that reality exists independently but our knowledge of it is shaped by perception) and critical theory (which emphasises power, social structures, and emancipation). But positivism, interpretivism, and pragmatism are the most commonly discussed in research methodology.
Why Research Philosophy Matters
Research philosophy matters because it shapes the entire research approach. It influences the kinds of questions a researcher asks, since different philosophies focus on different sorts of questions. It shapes the methods chosen — positivism favouring quantitative methods, interpretivism favouring qualitative methods, pragmatism supporting mixed methods. It affects how findings are interpreted and what conclusions are drawn. And it underlies the criteria by which research quality is judged.
Understanding your research philosophy helps you make coherent, justified methodological choices, ensuring that your approach, methods, and interpretation align with a consistent underlying philosophy. It also helps you understand and evaluate other research, recognising the philosophical assumptions that shape different studies. For these reasons, research philosophy, though abstract, is genuinely important to rigorous research.
As Dr. Madhuri Kanojiya, Founder of Empire Research Press, explains: “Research philosophy is the foundation beneath your methodology — the assumptions about reality and knowledge that shape everything else. A positivist sees an objective world to be measured; an interpretivist sees meanings to be understood; a pragmatist focuses on what works. These are not just abstract positions; they determine the questions you ask, the methods you choose, and how you interpret your findings. Understanding your philosophical foundation lets you make coherent, justified choices and ensures your research hangs together as a consistent whole.”
Research Philosophy in Practice
In practice, particularly in theses and dissertations, researchers are often expected to articulate their research philosophy, explaining the philosophical assumptions underlying their approach. This involves identifying the philosophical position that fits their research, explaining why it is appropriate, and showing how it shapes their methodology. While not every study requires explicit philosophical discussion, understanding the philosophical foundations strengthens any research by making its underlying assumptions clear and ensuring coherence between philosophy, approach, and methods. For research students, being able to articulate and justify a research philosophy is an important skill.
Conclusion
Research philosophy refers to the underlying beliefs and assumptions about reality (ontology) and knowledge (epistemology) that shape how research is conducted. The main philosophies — positivism (objective, measurable reality, favouring quantitative methods), interpretivism (socially constructed, subjective reality, favouring qualitative methods), and pragmatism (focused on what works, supporting mixed methods) — represent different foundations for research.
Though abstract, research philosophy has concrete consequences, shaping the questions asked, the methods chosen, and the interpretation of findings. Understanding your research philosophy enables coherent, justified methodological choices and helps you understand and evaluate other research. For rigorous research, particularly in theses and dissertations, grasping the philosophical foundations is genuinely valuable — revealing why research is conducted as it is and ensuring it forms a coherent, well-justified whole.
Frequently Asked Questions
Q: What is research philosophy?
Research philosophy refers to the system of beliefs and assumptions about the nature of reality and knowledge that underlies and shapes how research is conducted. It concerns fundamental questions: What is the nature of reality? What can we know, and how? What counts as valid knowledge? These assumptions, whether explicit or implicit, shape the entire research approach — the questions asked, the methods chosen, and how findings are interpreted. The main research philosophies are positivism, interpretivism, and pragmatism. Though abstract, research philosophy has concrete consequences for how research is designed and conducted, making it genuinely important to rigorous research.
Q: What are the main research philosophies?
The main research philosophies are positivism, interpretivism, and pragmatism. Positivism holds that reality is objective and measurable, gaining knowledge through objective observation, and is associated with quantitative research. Interpretivism holds that reality is socially constructed and subjective, gaining knowledge through understanding people’s experiences and meanings, and is associated with qualitative research. Pragmatism focuses on what works to answer the research question rather than committing to a single view of reality, often supporting mixed methods. Other positions include realism and critical theory, but these three are the most commonly discussed in research methodology, each shaping research differently.
Q: What is the difference between ontology and epistemology?
Ontology concerns the nature of reality — what exists and the nature of that existence, addressing questions like whether there is an objective reality independent of our perceptions or whether reality is socially constructed. Epistemology concerns the nature of knowledge — what knowledge is, what counts as valid knowledge, and how we can acquire it, addressing questions like whether we can objectively know reality or whether knowledge is always interpretive. In short, ontology is about reality and being, while epistemology is about knowledge and knowing. Together, these two sets of assumptions form the foundation of research philosophy, with different philosophies holding different ontological and epistemological positions.
Q: What is the difference between positivism and interpretivism?
Positivism holds that reality is objective, measurable, and independent of the observer, and that valid knowledge comes through objective observation and measurement — it seeks general laws and is associated with quantitative research, hypothesis testing, and statistical analysis. Interpretivism holds that reality is socially constructed, subjective, and shaped by human experience and meaning, and that knowledge comes through understanding people’s interpretations — it seeks in-depth understanding and is associated with qualitative research. In essence, positivism views the world as objectively measurable like the natural sciences, while interpretivism views social reality as constructed through human meaning, requiring understanding of subjective experiences rather than objective measurement.
Q: Why does research philosophy matter?
Research philosophy matters because it shapes the entire research approach. It influences the kinds of questions a researcher asks, the methods they choose (positivism favouring quantitative, interpretivism favouring qualitative, pragmatism supporting mixed methods), how findings are interpreted, and the criteria by which research quality is judged. Understanding your research philosophy helps you make coherent, justified methodological choices, ensuring your approach, methods, and interpretation align with a consistent underlying philosophy. It also helps you understand and evaluate other research by recognising the philosophical assumptions shaping different studies. Though abstract, research philosophy has concrete consequences and is genuinely important to rigorous, well-justified research.
