The realm of economics has long been dominated by the idea of the rational actor, a theoretical construct known as homo economicus. This concept suggests that individuals make decisions solely based on logic and personal benefit. However, Adam S. Hayes’ book, Irrational Together, highlights the limitations of this perspective by emphasizing the profound impact of social factors on financial behaviors.
Hayes, a sociology professor at the University of Lucerne, draws upon his academic background and extensive experience in finance.
He argues that the traditional behavioral critique fails to encompass the full spectrum of influences on economic behavior. Decisions are not solely dictated by individual cognition; they are also significantly shaped by social interactions and cultural context.

The role of social norms in financial decisions
One striking example Hayes presents is the tendency of employees to opt into 401(k) plans at a higher rate when the default option is to opt-out rather than opt-in. This simple change in framing reveals that decision-making is not merely a rational calculation of benefits but is also influenced by how choices are presented socially. By altering the context in which a financial choice is made, outcomes can differ dramatically.
Survey insights on personal relationships
Another revealing study discussed in the book explores homeowners’ decisions to downsize their living situations. Participants were asked about their willingness to sell homes featuring an extra bedroom, often used by a visiting mother-in-law. Interestingly, responses varied significantly based on the perceived relationship quality between the homeowner and the mother-in-law. Despite many citing financial reasons, the underlying social context played a crucial role in their decision-making process.
Investment decisions influenced by social dynamics
Investment professionals, often viewed as bastions of rationality, are not exempt from the sway of social factors. Hayes highlights a study concerning in-group bias, which shows that venture capitalists are more inclined to invest in startups led by teams sharing similar educational backgrounds and professional experiences. This phenomenon underscores how social affiliations can cloud financial judgment, leading investors to favor familiarity over objective evaluation of potential.
The implications of behavioral finance
Hayes’ research delves deeper into the implications of such biases within the investment landscape. He meticulously examines the rise of robo-advisors and their reliance on modern portfolio theory. By analyzing regulatory documents and engaging with various service providers, Hayes provides a comprehensive view of how these automated platforms might inadvertently reinforce existing biases rather than mitigate them. This raises important questions about the effectiveness of technology in aiding rational investment decisions.
Despite the challenges outlined in Irrational Together, Hayes acknowledges the complexity of predictive economics. Drawing on the wisdom of baseball legend Yogi Berra, he humorously notes that making accurate forecasts about the future is inherently difficult. Nevertheless, he emphasizes that understanding the collective impact of social forces can aid investment professionals in navigating the intricate web of personal biases and cultural influences.
Strategies for navigating social influences
For those in the investment field, Hayes offers valuable insights on minimizing the detrimental effects of social pressures on financial decision-making. Recognizing the role of cultural norms, religious beliefs, and ideological influences can empower professionals to better understand their clients’ motivations and behaviors. By fostering awareness of these dynamics, advisors can help clients make more informed, rational choices that align with their long-term financial goals.
Ultimately, Irrational Together serves as a compelling reminder that economic behaviors are deeply intertwined with social contexts. For those seeking to enhance their understanding of economic decision-making, this book provides a rich tapestry of insights and research findings that challenge conventional wisdom and encourage a more nuanced view of financial choices.
