The question I want to examine in this paper is if and how falsification as a method and Popper’s philosophy of science in general is appropriate for and applicable to economic research. To begin with I will start with a short introduction about Karl Popper and his philosophy. Then I will explain and evaluate the concept of falsification with its strengths and weaknesses and its use for science in general. Afterwards I will examine the influence and actual usage of falsification in economics in general to finally evaluate the chances and limits of the concept in this area of science.
It is often said that a significant characteristic of economic research is the strong staying power of theories, even with contradicting empirical evidence. Moreover, the scientific character of economic science is often questioned. In this context economic research is criticised for a lack of falsification or even a lack of falsifiability. But is it true and what does this mean?
The concept of falsification as a deductive method was brought up and made popular by the Austro-British philosopher Karl Popper in the 1930s. In contrast to the idea of gaining truth or principles through a lot of empiric observations (inductive method), he claimed that it is logically only possible to refute general statements by empirical observations. Consequently, Popper advocates for a method of research through trial and error. Science should use the method of falsification and for him the use of it is the demarcation criterion between science and non-science. Karl Popper’s methodological writings have been a cause of debate since the 1930s.
This scientific method is nowadays established particularly in natural sciences where you can tell more easily if a theory is wrong than in other disciplines. Economic research is part of the second group of disciplines, where we often find huge differences between Popper’s prescriptions and the common practice and where normative statements are often part of all considerations.

Chapter Summaries
1. Introduction: This introductory chapter sets the stage by highlighting the enduring nature of economic theories despite conflicting empirical data. It introduces the ongoing debate surrounding the scientific validity of economics and the criticism of its alleged lack of falsification or falsifiability. The chapter positions Karl Popper's concept of falsification as a central theme and outlines the paper's objective: to analyze the suitability and applicability of Popperian falsification within economic research. The structure of the paper is presented, foreshadowing the exploration of Popper's philosophy, the evaluation of falsification, and its application within the context of economics.
2. Karl Popper and his Philosophy of Science: This chapter provides biographical context for Karl Popper, tracing his intellectual development and influences. It highlights his critique of logical positivism and the development of his influential work, "The Logic of Scientific Discovery." The chapter emphasizes Popper's emphasis on falsification as a key element of the scientific method, contrasting it with inductive reasoning and highlighting its significance as a demarcation criterion between science and non-science. The discussion of Popper's work establishes the theoretical foundation for the subsequent analysis of falsification's application within economics.
3. Falsification and Economics: This chapter delves into the application and implications of Popper's falsification within the field of economics. It explores the extent to which Popper's ideas have influenced economic thought and practice. The chapter analyzes both the strengths and limitations of applying falsification to economic research, considering the unique challenges posed by the complexities and normative aspects often inherent in economic models and theories. It examines the practical challenges encountered in falsifying economic theories and considers broader interpretations of Popper's falsificationism. Finally, it discusses the potential consequences of adopting—or failing to adopt—a falsificationist approach to economic inquiry.

Frequently Asked Questions: Applicability of Popperian Falsification in Economics
What is the main topic of this paper?
This paper explores the applicability of Karl Popper's philosophy of science, particularly his method of falsification, to economic research. It investigates whether falsification offers a suitable methodological framework for economics, given the persistence of economic theories despite contradictory evidence.
Who is Karl Popper, and what is his relevance to this paper?
Karl Popper was a prominent philosopher of science known for his concept of falsification. This paper uses Popper's ideas as a lens to analyze the methodology of economics. The paper examines Popper's critique of logical positivism and his emphasis on falsification as a crucial aspect of the scientific method.
What is the method of falsification?
Falsification, as championed by Popper, is a method of scientific inquiry where theories are tested by attempting to disprove them. Instead of seeking confirmation, scientists should actively look for evidence that contradicts their theories. A theory that withstands multiple attempts at falsification is considered stronger, but it can never be definitively proven true.
What are the key themes explored in this paper?
The key themes include the applicability of Popper's falsification method to economics; the strengths and weaknesses of falsification as a scientific method; the historical influence of Popper's ideas on economic thought; the challenges of applying falsification in economics (especially concerning normative statements); and the implications of adopting a falsificationist approach for economic science.
What are the main chapters and their content?
The paper consists of four chapters. Chapter 1 provides an introduction, highlighting the persistence of economic theories despite conflicting evidence. Chapter 2 focuses on Karl Popper and his philosophy of science, detailing his work and the concept of falsification. Chapter 3 delves into the application of falsification within economics, exploring its strengths, limitations, and implications. Chapter 4 presents the conclusion.
What are the challenges of applying falsification to economics?
Applying falsification to economics presents unique challenges. Economic models often incorporate normative statements (value judgments) making them difficult to falsify through purely empirical means. The complexity of economic systems and the difficulty of isolating variables also contribute to the challenges.
What are the implications of adopting a falsificationist approach to economics?
Adopting a falsificationist approach could lead to a more rigorous and self-correcting economic science. It might encourage economists to more critically evaluate their theories and be more open to revising or rejecting theories in light of contradictory evidence. However, the practical challenges associated with falsification in economics must also be considered.
What are the keywords associated with this paper?
Keywords include: Falsification, Karl Popper, Philosophy of Science, Economics, Methodology, Scientific Method, Empirical Evidence, Inductive Reasoning, Deductive Reasoning, Normative Statements, and Falsifiability.
