A study on mixed methods research from different research philosophy perspectives (information from perplexity.ai).
My question 1: What is mixed methods research all about with references to: (1) positivism, (2) interpretivism, (3) pragmatism and (4) critical realism?"
The reply: "Mixed methods research (MMR) is an approach that combines both quantitative and qualitative research methods to provide a more comprehensive understanding of research problems. It draws on multiple philosophical paradigms, including positivism, interpretivism, pragmatism, and critical realism, each of which contributes distinct perspectives to the design and interpretation of research.
Positivism: This paradigm underpins much quantitative research. Positivism emphasizes objective measurement, hypothesis testing, and the search for universal laws. It assumes a single, measurable reality that can be discovered through empirical observation and logical analysis. In mixed methods, positivism typically informs the quantitative aspects, focusing on causality, measurement, and generalizability of findings.
Interpretivism: Interpretivism focuses on understanding the meanings and experiences of individuals, emphasizing that reality is socially constructed and subjective. It informs qualitative research methods that explore how people interpret and make sense of their world. In MMR, interpretivism complements positivism by providing depth and context to the quantitative data, addressing the "how" and "why" questions.
Pragmatism: Pragmatism is often viewed as the dominant paradigm in mixed methods research because it prioritizes the practical application and usefulness of research findings. It rejects strict adherence to any single philosophical position in favor of using the methodology or combination of methods best suited to addressing the research question. Pragmatism embraces both qualitative and quantitative data to develop a holistic understanding of complex issues, emphasizing actionable knowledge and problem-solving.
Critical Realism: Critical realism combines a realistic ontology—that there is a reality independent of our perceptions—with the understanding that our knowledge of that reality is inevitably theory-laden and fallible. In MMR, critical realism acknowledges that observations are influenced by prior beliefs and social contexts but seeks to uncover underlying mechanisms and structures that explain observed phenomena. It bridges subjective interpretation and objective analysis by emphasizing the contextual and often hidden causes behind empirical observations.
In summary, mixed methods research integrates these paradigms to leverage the strengths of each. Positivism offers rigor and generalizability through quantitative measures; interpretivism provides depth through qualitative insights; pragmatism allows methodological flexibility focused on practical outcomes; and critical realism offers a nuanced philosophical stance recognizing both objective reality and subjective understanding.
This pluralistic philosophical foundation makes mixed methods particularly suited for addressing complex research questions that require multiple types of evidence and ways of knowing.
My question 2: "Clarify the discussion a bit more on our discussion topic with the following two research theme examples for illustration:
The reply: "To clarify the mixed methods research discussion using your two provided themes, here is how the four paradigms—positivism, interpretivism, pragmatism, and critical realism—can be illustrated in each case:
Example 1: "To evaluate how the present weak Hong Kong housing market affects citizens' confidence to purchase an apartment within 1 year"
Positivism: This would involve quantitatively measuring the housing market conditions (e.g., price indices, transaction volumes) and citizens’ confidence levels via structured surveys or market sentiment indices. For instance, existing research has used indices derived from news sentiment and Google search trends to objectively track Hong Kong’s housing market sentiment and buyer incentives. Statistical analysis could test hypotheses about the relationships between market weakness and confidence.
Interpretivism: Qualitative methods such as interviews or focus groups with potential homebuyers could explore how individuals personally perceive the housing market, reasons behind their confidence or hesitation, and the social or cultural meanings attached to owning property in Hong Kong. This would provide richer context beyond numbers about the "why" behind confidence levels.
Pragmatism: A mixed methods approach here would combine the objective quantitative indicators of market strength and confidence with qualitative insights about citizen sentiments to form a comprehensive evaluation. The goal would be practical: informing policymakers or developers about factors influencing purchasing decisions, using all relevant data to guide recommendations.
Critical Realism: This paradigm would emphasize uncovering the underlying mechanisms affecting the housing market and confidence, such as macroeconomic forces, government policies, and social perceptions that might not be immediately observable. It acknowledges that people’s perceptions are influenced by social and media contexts but seeks to relate these to real market conditions and structural causes.
Example 2: "To evaluate how the preferred leadership style of Gen Zs affects employees' innovation behavior in the Hong Kong Insurance Sector"
Positivism: Quantitative surveys could measure preferred leadership styles (using validated scales) and innovation behaviors (e.g., frequency of idea generation or implementation) among employees in insurance companies. Statistical techniques could test for correlations or causal effects.
Interpretivism: Qualitative interviews or ethnographic studies could explore how Gen Z employees interpret leadership behaviors and how these influence their motivation and innovation practices, capturing subjective experiences and meanings in organizational culture.
Pragmatism: Using both quantitative and qualitative data, this approach would aim to deliver actionable insights for insurance sector managers on how leadership might be adapted to foster innovation effectively among Gen Z workers. The design is flexible and driven by the research questions and practical outcomes.
Critical Realism: Here, critical realism would aim to understand both the observable behaviors and the deeper social structures or organizational dynamics that shape innovation. It would recognize that employee behavior is influenced by broader industry norms, power relations, or institutional contexts that shape how leadership is enacted and received.

By situating your examples within these paradigms, you can design mixed methods research that leverages objective measurements and rich contextual understanding to address complex social and organizational phenomena in Hong Kong’s housing and insurance sectors. This illustrates how mixed methods draw on these philosophical foundations to produce both rigorous and meaningful research outcomes.
