Why do we treat teenagers like ticking time bombs? For decades, the dominant story about young people has been that their underdeveloped brains make them impulsive and irrational\u2014leaving adults no choice but to control them or shield them from consequences.<\/p>\n\n\n\n

Developmental psychologist David Yeager challenges this \u201cneurobiological incompetence\u201d model. Keep reading to learn how the model misses the mark and leads us astray.<\/p>\n\n\n\n

The Neurobiological Incompetence Model<\/h1>\n\n\n\n

Conventional wisdom in Western culture says that young people are basically impulsive, bad at thinking for themselves, and unable to make good choices. According to developmental psychologist David Yeager, this \u201cneurobiological incompetence model\u201d is flawed and leads to ineffective ways of relating to adolescents.<\/p>\n\n\n\n

In his 2024 book 10 to 25<\/em><\/a>, Yeager explains that the model rests on 20th-century scientific findings that the adolescent brain lacks a fully developed prefrontal cortex (the part of the brain that governs decision-making). Studies have also shown that the limbic system (the brain\u2019s seat of emotion) is more active in young people than in adults. These findings have led to the idea that young people can\u2019t control themselves, so they need adults to tell them what to do. In other words, we assume that young people are neurobiologically incompetent<\/em>\u2014their brains don\u2019t yet work as well as adults\u2019 do, so they can\u2019t behave properly.<\/p>\n\n\n\n

(Shortform note: By calling this the \u201cneurobiological incompetence model\u201d Yeager points out how we\u2019ve medicalized<\/em> young people\u2019s development by treating their normal human experiences as medical conditions. He traces the origin of this to a sloppy interpretation of the ancient Greek allegory<\/a> where a charioteer (reason) has to control wild horses (passions). We tend to interpret this as an explanation of young people\u2019s emotionality. But Plato, who created the allegory, didn\u2019t seem to intend this. Rather, the allegory was about his notion of the human soul<\/a> as a three-part composite striving toward truth, goodness, and beauty\u2014one good horse, one bad horse, and one charioteer trying to coordinate them.)<\/p>\n\n\n\n

Incompetence-Based Mentoring Approaches<\/h3>\n\n\n\n

Yeager is a developmental psychology professor at UT Austin who earned his PhD from Stanford’s School of Education. Before entering academia, he taught middle school. In his book 10 to 25<\/em>, he identifies two main schools of thought based on the view that young people are neurobiologically incompetent:<\/p>\n\n\n\n
