Book Review: 10-25 by David Yeager

David Yeager’s 10-25 is an insightful guide that bridges generational divides, offering educators and parents profound insights into understanding, communicating, and mentoring young people. He was once a middle-school teacher, and was inspired by all of the challenges and tension he witnessed within the educational system. “I felt that I wanted to do research on better approaches…”

“10 – 25” is the title because the brain is still in a developmental period. He demystifies common understandings (read: misunderstandings) about how the brain develops and why behaviours are so predictable and hard to understand for older generations.

Yeager’s approach integrates compelling psychological and sociological research, making this book essential for anyone involved in nurturing the next generation’s potential. He went and met and interviewed those adults who are getting it right, but also who are getting it wrong.

You’d be interested in this book if:

1. You’re committed to enhancing intergenerational communication. Yeager challenges readers to envision a world where interactions between older adults and young people consistently inspire enthusiasm and capability. He writes, “Imagine a world where older adults interact with young people, 10 – 25, in ways that reliably leave the next generation inspired and enthusiastic.” This vision underscores the book’s purpose: to equip adults with strategies for genuinely understanding youth and creating space for their growth and leadership.
2. You’re interested in the science of effective mentorship. Yeager introduces key concepts such as the Mentor’s Dilemma, first discovered by Cohen at Stanford University, highlighting how mentors often face challenges in delivering impactful feedback. He emphasizes “wise feedback,” scientifically proven to positively influence diverse populations. By deeply understanding how different generations perceive feedback and support, mentors can significantly enhance their communication, leaving both mentor and mentee feeling inspired, capable, and supported.

An amazing interivew with Carol Dweck and Davie Yeager:

1. You’re concerned about society’s persistent misunderstanding of youth. Yeager provocatively asks, “What if the problem with young people is with us?” He critiques traditional societal strategies, suggesting that ineffective approaches to youth behavior signal a need for fundamental change. Drawing from examples such as teen anti-smoking initiatives, Yeager illustrates that young people are capable of making wise decisions when approached with understanding and respect rather than suspicion and mistrust.
2. You’re ready to move beyond outdated narratives of adolescence. The author argues against the “Neurobiological Incompetence Model,” which promotes the idea that youth cannot be trusted to make consequential decisions. Yeager asserts, “Let’s rehabilitate puberty’s reputation,” urging readers to reconsider societal fears surrounding teenage development. By acknowledging youth’s genuine needs for respect, prestige, and agency, educators and parents can better support young people’s development and decision-making capabilities.
   

   The rate of clinical signifcant rates of anxiety and depression have gone up since the ’90s, while the rate of other risk behaviours have gone down (teenage pregancy, crime and impaired driving…But mental health has decreased and unemployment has increased. There is a link to be explored.

3. You’re passionate about purposeful mentoring and coaching. Yeager defines mentoring as aligning one’s resources with the best long-term interests of youth. Drawing from Daniel Coyle’s The Culture Code, he provides practical strategies and illuminating case studies, such as Whole Foods’ deficit-based hiring approach versus companies embracing youth’s desire for prestige and agency. Yeager also debunks myths perpetuated by narratives like “Stand and Deliver,” highlighting effective, collaborative approaches such as “Treaty Co-Authoring,” where mentoring relationships thrive on mutual respect and shared value.
4. You want practical strategies for meaningful feedback and productive stress. The book includes insightful techniques like “The first day of class speech study,” emphasizing clear expectations, transparent support, and growth-oriented beliefs—aligned with Carol Dweck’s growth mindset principles. Yeager also addresses productive stress management, echoing Lisa Damour’s research: “Before I take each quiz, I remind myself that nerves are normal and I am prepared,” showcasing how stress, when effectively reframed, can enhance performance.

Cultivating a Mentor Approach
Effectively guiding colleagues who may be younger or less experienced is highly relevant in today’s workplaces. Similarly, parents, mentors (like myself, working with college-aged students), and supervisors of entry-level employees in their early 20s will find valuable insights in this approach.

The mentor approach includes:
– Honouring Perspectives: Recognizing and valuing young individuals’ viewpoints enhances mutual understanding and respect.
– Inquiry-Based Dialogue: As Socrates suggested, “I shall only ask him and not teach him, and he shall share the inquiry with me.” This method emphasizes fostering critical thinking by posing thoughtful questions rather than providing immediate answers.
– Openness: Clearly communicating your intentions and expectations to build trust and avoid miscommunication.
– Setting High Expectations: Encouraging growth by challenging young people to reach high standards, coupled with strong support rather than overly protective guidance.

These approaches leverage the natural motivational drives of young people’s developing neurobiology, empowering them to achieve higher levels of performance. Studies consistently show individuals excel most in environments characterized by significant challenge paired with robust support, findings validated in educational institutions, universities, and corporate contexts.

10-25 is a rich, essential read for educators and parents seeking practical, scientifically-backed strategies for positively engaging young people, improving intergenerational communication, and nurturing authentic leadership.
