Research Methodology: From First Principles to Policy

First Principles in Research

Shifting from Case Studies to First Principles

  • Harvard Business School MBA Program: Primarily uses case studies, where students analyze a situation and propose solutions.

  • Lawson: Similar approach to case law.

  • First Principles Approach: Instead of basing solutions on existing cases or subjective opinions, this method involves going back to fundamental truths or assumptions, building up a theory, and then testing that theory systematically.

The Research Question

  • Fundamental Importance: The research question is the most crucial part of the entire research process.

  • Origin: Questions can arise from observations or ponderings about the world.

    • Personal Example (PhD Thesis): The question, "Why are there so many more overweight and obese people today than before?" This was observed by comparing body sizes in media from different eras.

    • Everyday Observations:

      • Why do fast-food restaurants, car dealerships, and gas stations cluster on the same street in every town?

      • Why are there more tent cities now?

      • Why is smoking less prevalent than before (e.g., smoking indoors was once common during the instructor's undergrad years)?

  • Focus and Complexity: It's vital to develop a clear question and stay focused, as the world is complex and prone to

Shifting from Case Studies to First Principles

  • Harvard Business School MBA Program: Primarily uses case studies, where students analyze a specific business situation, often derived from real-world scenarios, to diagnose problems and propose actionable solutions based on precedents and established frameworks. The emphasis is on pattern recognition and application of known solutions.

  • Lawson: Similar approach to case law, where legal decisions are based on precedents established in previous judicial rulings. This method relies heavily on historical examples and authoritative interpretations.

  • First Principles Approach: In contrast, this method advocates for an approach that disregards or questions existing assumptions and frameworks. It involves:

    • Deconstruction: Breaking down a problem or phenomenon to its most basic, irreducible components or fundamental truths. These are things that are known to be true and cannot be logically deduced from anything else.

    • Reconstruction: Building up a new theory, solution, or understanding from these fundamental truths, without being constrained by conventional wisdom or existing models. This allows for innovation and novel solutions that might not be apparent through case studies or precedent.

    • Systematic Testing: The newly constructed theory or solution is then rigorously tested to validate its efficacy and robustness against real-world data or empirical observations. This is a crucial step to ensure the theory is not merely a philosophical construct but has practical applicability.

The Research Question

  • Fundamental Importance: The research question is not merely a starting point, but the absolute cornerstone of any research endeavor. A well-formulated question dictates the scope of the study, the methodology employed, the data collected, and ultimately, the conclusions drawn. Its clarity and precision are paramount, as a vague or ill-defined question can lead to unfocused efforts and inconclusive results.

  • Origin: Research questions often originate from genuine intellectual curiosity, observations of phenomena that defy easy explanation, or a desire to understand 'why' things are the way they are. This can manifest in several ways:

    • Personal Example (PhD Thesis): The initial observation of a significant increase in overweight and obese individuals over time, noted by comparing depictions in media from different historical periods, led to the question: "Why are there so many more overweight and obese people today than before?" This question seeks to uncover the underlying causes and systemic factors contributing to this societal shift.

    • Everyday Observations: These are common occurrences that prompt deeper inquiry:

      • "Why do fast-food restaurants, car dealerships, and gas stations cluster on the same street in every town?" This question might explore economic incentives, consumer behavior, zoning laws, or competitive strategies.

      • "Why are there more tent cities now?" This could lead to research into socio-economic factors, housing policies, mental health services, and shifts in urban planning.

      • "Why is smoking less prevalent than before (e.g., smoking indoors was once common during the instructor's undergrad years)?" This question could investigate public health interventions, changes in social norms, educational campaigns, and legislative measures that influenced smoking rates.

  • Focus and Complexity: It's absolutely vital to develop a clear, precise, and manageable research question and to maintain a sharp focus throughout the research process. The world is inherently complex, with numerous interconnected variables influencing any given phenomenon. Without a defined focus, research can become sprawling and unfocused, leading to:

    • Scope Creep: The tendency for research to expand beyond its initial boundaries, diluting efforts and resources.

    • Confusion: Difficulty in interpreting results due to a multitude of uncontrolled variables.

    • Lack of Specificity: Inability to provide definitive answers or actionable insights.
      Therefore, narrowing down the question to address a specific, testable aspect of a broader problem is crucial for successful and impactful research.
