  • Resumen

  • Welcome to Unraveling Behavior, a science podcast where we uncover the patterns driving human judgment and decision making. In each episode, Dr. Ana Sofia Morais sits down with a researcher to explore how people make decisions, how they handle risk, and how our surroundings and the online world shape our behavior. Unraveling Behavior is a non-commercial initiative from the Center for Adaptive Rationality, a research group at the Max Planck Institute for Human Development in Berlin.

  • Dr. Simon Ciranka: How Brains, Peers, and Environments Fuel Risky Behaviors in Teens
    Mar 4 2025

    In this episode, I am joined by Dr. Simon Ciranka, a cognitive scientist and developmental psychologist, to explore why teens take risks. Dr. Ciranka explains that parts of the brain that pursue rewards develop early, while parts that control impulses develop later. This imbalance makes teens especially sensitive to rewards like positive feelings and experiences. We also discuss the role of environmental factors. Since severe consequences are rare, teens often experience the rewards of risky behavior without facing immediate negative outcomes. This can foster a false sense of security and diminish caution. Societal guardrails, such as legal age limits for driving or drinking, further shape when and how adolescents take risks. Our conversation extends to peer relationships, which can have both positive and negative effects. While peers can offer valuable lessons from others' mistakes, they can also push teens toward riskier decisions. Teens often think risky behaviors are more common among their peers than they really are, which can lead to more risk-taking. We also explore effective strategies for reducing dysfunctional risk-taking, such as early education and correcting wrong beliefs about how common risky behaviors are. By the end of this episode, listeners will better understand why teens take risks—not as a sign of recklessness, but as a complex interplay of developmental, social, and environmental factors.

  • Shahar Hechtlinger: The Psychology of Life's Most Important Decisions
    Jan 2 2025

    In this episode, I sit down with Shahar Hechtlinger, a PhD candidate in Psychology, to explore transformative life decisions—choices that can change who we are, such as becoming a parent, changing careers, or moving to a new country. We discuss how much decision-making research focuses on idealized models but lacks insights into how people actually make these life-altering choices. We examine why the expected utility model—a traditional way of thinking about rational decisions—does not really work for these situations, largely because the future is uncertain and what matters to us can shift over time. Drawing on the work of philosopher L. A. Paul, we discuss how these experiences challenge conventional notions of rationality and require a different approach. Shahar Hechtlinger introduces a new conceptual framework from her research, offering simple strategies for navigating transformative life decisions, including imagining your ideal self, considering future regret, and taking incremental steps to manage irreversible choices. We also discuss findings from Shahar’s most recent study, showing that while people often rely on simpler strategies for themselves, they tend to recommend more complex approaches for others. This episode equips listeners with simple strategies and real-life examples to navigate transformative decisions, emphasizing the value of embracing uncertainty when facing life’s most significant choices.

  • Dr. Tomás Lejarraga: How Birth Order Influences Risk Taking Among Siblings
    Nov 4 2024

    In this episode, I am joined by Dr. Tomás Lejarraga, a behavioral scientist working at the intersection of economics and psychology. We explore how birth order influences siblings' willingness to take risks. Our discussion begins by examining the long-held hypothesis that younger, laterborn children are more prone to taking risks than their older siblings. Dr. Lejarraga shares insights from a study on risk-taking behavior in adulthood, revealing surprising findings that challenge this belief. We also discuss a second study suggesting that while birth order effects cannot be entirely dismissed, they are primarily observable in younger ages and may not persist throughout life. Additionally, we delve into the various methods scientists use to assess individuals' willingness to take risks, the competitive dynamics among siblings, the implications of null results, and the influence of environment and culture on birth order effects. The episode will help listeners understand the complexities of sibling differences and how family environments shape our behavior.
