The traditional economic model often relies on the concept of homo economicus, portraying individuals as perfectly rational decision-makers. However, this view faces scrutiny from behavioral economics, which highlights the gaps between theoretical models and actual behavior. Adam S. Hayes’s book Irrational Together explores these critiques, illustrating how social influences significantly impact economic choices, often diverging from individual rationality.
Hayes, a sociology professor at the University of Lucerne, leverages his background in finance to argue that decision-making is influenced not only by personal calculations but also by cultural and social contexts.
He provides compelling evidence that the environment surrounding decisions can lead individuals to act against their own financial interests.

The influence of social norms on economic behavior
A key insight from Irrational Together is that social norms can distort financial decisions. For instance, when homeowners consider downsizing to save money, they often weigh their relationships with family members, such as a mother-in-law who visits occasionally. Hayes’s research indicates that the perceived harmony of these relationships often sways homeowners’ decisions more than pure financial logic would suggest. Respondents frequently cited financial reasons for their choices, yet social implications heavily influenced their actions.
Case study: 401(k) participation
A clear example of how framing affects decision-making is seen in the participation rates of employees in 401(k) plans. Studies reveal that automatic enrollment, with an opt-out option, results in significantly higher participation rates compared to requiring employees to actively opt in. This difference underscores the powerful role of context and social framing in economic behavior.
Group dynamics and investment choices
Investment professionals often believe their decisions are based solely on objective financial metrics. However, Irrational Together shows that social dynamics can also play a crucial role. For instance, a study highlighted by Hayes found that venture capitalists often exhibit in-group bias, favoring startups led by individuals with similar educational and professional backgrounds. This bias can lead to a lack of diversity in funded projects, as personal preferences overshadow rational analysis.
The impact of technology on decision-making
Hayes examines the phenomenon of robo-advisors, discussing how these automated platforms may inadvertently reinforce existing biases. By relying on standardized models rooted in modern portfolio theory, these services could lead to collective financial decisions that overlook unique individual circumstances. This raises important questions about the effectiveness and potential drawbacks of relying solely on technology for financial planning.
While Hayes acknowledges the challenges in predicting future economic outcomes, he emphasizes the importance of understanding the interplay between social forces and economic behavior. He humorously references Yogi Berra’s famous quote about the difficulty of making predictions, highlighting the complexity of human behavior in economic contexts.
Through these themes, Irrational Together encourages investment professionals to reevaluate their approaches and acknowledge the multifaceted influences on decision-making. It serves as a reminder that while individuals may strive for rationality, the social frameworks within which they operate can lead to decisions that diverge from traditional economic models.
Hayes’s work enriches our understanding of the collective dynamics shaping financial behavior. By recognizing the impact of social norms and relationships, investment professionals can better navigate client interactions and enhance their decision-making processes. This book is essential for anyone seeking to deepen their understanding of the social underpinnings of economic behavior.
