Does reality exist outside of your own perception?

In short: The way you approach a research question depends entirely on what you believe about the nature of reality itself. Are facts objective truths waiting to be measured, or are they subjective stories constructed by human experience? Your philosophical starting point dictates every methodological choice you make.

Research philosophy refers to the core set of beliefs, assumptions, and principles that underpin how a study is conducted. It addresses fundamental questions about what reality is like and what kind of knowledge can be produced from it. While these concepts can feel abstract, they are the foundation of academic rigor; without a clear philosophical position, research design choices risk appearing arbitrary rather than coherent.

Reality being separate from those who perceive it forms the core foundation of positivism. This paradigm prioritizes objective observation and measurement, mirroring the hard sciences like physics or astronomy. In practice, positivism manifests as quantitative methodologies—such as randomized control trials—designed to achieve generalizability and replicability. If you are measuring causal relationships using numbers, you are operating within a positivist framework.

Interpretivism occupies the opposite end, asserting that reality is socially constructed and subjective. Here, knowledge is built by the observer through their unique experiences. This paradigm is best suited for qualitative methodologies, such as open-ended interviews or textual analysis, which aim to uncover the specific meanings people assign to their lives. For instance, while a positivist might measure the intensity of chronic pain, an interpretivist seeks to understand what living with that pain feels like.

Pragmatism offers a middle ground for studies involving both hard and soft phenomena. Rather than committing to one mutually exclusive philosophical stance, pragmatists focus on the utility and application of the findings. This often leads to mixed-methods research, such as combining test results from an intervention group with qualitative interviews from the same participants. Ultimately, your paradigm is often chosen for you by your research goals: if you seek meaning, you are likely an interpretivist; if you seek cause, you are a positivist.
