Behavioral Finance: Criticism, Scrutiny, and Goals-Based Investing
The field of economics and finance is today divided into two main camps: normative and behavioral. The normative camp addresses what actions a person should take to achieve rationality, while the behavioral camp examines and catalogs real-world behaviors. Although both camps now acknowledge the validity of each other, they each hold unique perspectives that have shaped the landscape of finance.
Historical Context of Behavioral Finance
The division between these two camps began with significant developments in the 1950s. In 1953, Maurice Allais published the results of an experiment demonstrating that real people do not always make decisions according to the axioms of von Neumann and Morgenstern's rational choice theory. This sent a shockwave through the academic community. In response, in 1959, Harry Markowitz, a Nobel laureate, refuted Allais's conclusions by arguing that individuals acting according to what seemed irrational according to these axioms were simply making rational choices given their goals. This exchange marked the birth of the normative-behavioral divide.
Critical Perspectives on Behavioral Finance
While behavioral finance is not exactly criticized, it is subject to the same scrutiny as any other academic discipline. As new research emerges, it challenges and refines existing theories, pushing the boundaries of our understanding of financial behavior. One such emerging line of thinking is goals-based investing. This approach seeks to reconcile the perceived irrationalities identified by normative theory with the observed behaviors of the behavioral camp.
Goals-Based Utility Theory and Its Implications
Goals-based utility theory suggests that many actions labeled as irrational by normative theory might, in fact, be rational if we consider the goals people are trying to achieve. For example, while normative theory may consider gambling always irrational, mathematical analyses have shown that there are scenarios where gambling can be a rational decision based on an individual's goals. This theory bridges the gap between the two camps, positing that both sides are sometimes too quick to label human behavior as irrational.
Implications and Future Research
As this line of research evolves, it holds the potential to reshape our understanding of financial decision-making. The upcoming book delves into the mathematical details of goals-based utility theory, providing a deeper dive into its implications. For those interested in this topic, the book offers insights that can enhance one's understanding of financial behavior and decision-making.

This is an area where the conversation is still unfolding, making it both challenging and rewarding to explore.
Conclusion
In conclusion, while behavioral finance has its critics, it is ultimately part of a broader academic discourse. The emerging goals-based investing perspective offers a novel approach to reconciling the perceived irrationalities with real-world behaviors. As research continues to evolve, it is an exciting time to be part of this dynamic field of study.
