Alder’s Law: Unraveling the Fallacies of Decision-Making


In the realm of decision-making, Alder’s Law presents a crucial mental model. Anchored in human psychology, this model refers to the tendency of individuals or groups to make irrational decisions that are contrary to their best interests. Understanding the concept of Alder’s Law is essential for avoiding these pitfalls and making informed choices. In this comprehensive blog post, we will define Alder’s Law, explore its relevance in decision-making processes, provide examples across different contexts, examine the underlying biases, offer practical advice on identifying and avoiding this fallacy, and emphasize the value of awareness and active avoidance of this mental trap.

Defining Alder’s Law and Its Relevance in Decision-Making

Alder’s Law refers to the phenomenon where individuals or groups make decisions that go against their best interests due to various biases and cognitive distortions. It is named after the psychologist Alfred Adler, who observed this pattern in human behavior. This mental model highlights the importance of understanding the underlying influences on decision-making and the potential consequences of falling prey to irrational choices.

Examples of Alder’s Law in Various Contexts

  1. Personal Life Decisions: Imagine a person who consistently prioritizes short-term pleasure and instant gratification over long-term goals and well-being. They engage in behaviors such as excessive spending, unhealthy eating habits, or procrastination. Despite knowing the negative consequences, they succumb to the allure of immediate satisfaction, disregarding their own best interests and long-term happiness.
  2. Business Scenarios: In a business context, Alder’s Law can manifest when leaders or decision-makers prioritize maintaining the status quo over embracing necessary changes. This could involve resisting innovation, dismissing market trends, or failing to adapt to evolving customer needs. By clinging to familiar strategies, businesses risk stagnation and failure to seize new opportunities.
  3. Public Policy-Making: Alder’s Law can influence public policy-making when policymakers prioritize short-term political gains or appeasing certain interest groups over evidence-based, long-term solutions. This can lead to the neglect of pressing issues, ineffective policies, and ultimately harm to the overall welfare of society.

Mental Biases and Psychological Underpinnings

Several cognitive biases contribute to Alder’s Law. One such bias is the status quo bias, where individuals have a natural inclination to maintain existing conditions rather than embracing change. This bias often stems from a fear of the unknown and a preference for stability, even when it may not be in one’s best interest.

Another relevant bias is the confirmation bias, wherein people seek information that confirms their pre-existing beliefs or biases, while disregarding or dismissing conflicting evidence. This bias can reinforce irrational decision-making by cherry-picking information that aligns with one’s desired outcome, leading to distorted judgments.

Additionally, the framing effect plays a role in Alder’s Law, as decisions can be influenced by how choices are presented or framed. Individuals may make different choices based on the positive or negative framing of the options, even if the objective outcomes remain the same.

Identifying and Avoiding Alder’s Law

To identify and avoid falling into the trap of Alder’s Law, consider the following strategies:

  1. Increase self-awareness: Reflect on your own decision-making tendencies and biases. Be mindful of situations where you might be prioritizing short-term gains over long-term interests or clinging to familiar routines without considering the potential benefits of change.
  2. Seek diverse perspectives: Actively seek out alternative viewpoints and gather a range of opinions and information before making decisions. Engage in constructive debates and discussions to challenge your own assumptions and biases.
  3. Embrace critical thinking: Develop critical thinking skills to evaluate information objectively. Practice questioning assumptions, seeking evidence, and considering potential long-term consequences before making choices.
  4. Consider the bigger picture: Take a step back to assess the broader implications of your decisions. Consider the impact on yourself, others, and future outcomes. Avoid making choices solely based on immediate gains or losses.


Alder’s Law serves as a reminder of the inherent biases and cognitive distortions that can cloud our decision-making processes. By understanding this mental model and the underlying biases at play, individuals can make more informed choices aligned with their long-term well-being and best interests. By cultivating self-awareness, seeking diverse perspectives, embracing critical thinking, and considering the broader implications of decisions, we can navigate the complexities of decision-making more effectively. By actively avoiding Alder’s Law, we empower ourselves to make rational choices and create positive outcomes in both personal and professional realms.
