How We Grow Up: Inside the Adolescent Brain with Matt Richtel
In this episode of Good Inside, Matt Richtel and Dr. Becky Kennedy explore adolescence as a key developmental phase. They discuss how biological changes during puberty make adolescent brains more receptive to external influences, as evidenced by Stanford research showing teens respond more strongly to strangers' voices than their parents'. This discussion addresses the mismatch between early puberty onset and slower prefrontal cortex development.
The conversation examines how parents can effectively support their adolescents through this period of change. Kennedy and Richtel outline strategies for maintaining boundaries while allowing independence, and explain why teen behavior that seems like rejection is actually a normal part of development. They share practical approaches for responding to teen emotions and helping adolescents develop emotional resilience.

The Biological and Developmental Purpose of Adolescence
In this podcast episode, Matt Richtel and Becky Kennedy explore the crucial role of adolescence in human development. Richtel explains that during this phase, young people begin integrating lessons from previous generations while exploring new possibilities for themselves. This process is facilitated by a hormone surge during puberty that increases the brain's sensitivity to external environments.
A Stanford study supports this understanding, showing that adolescent brains respond more strongly to strangers' voices than parents' voices, indicating a natural shift toward external influences. Kennedy notes that with earlier onset of puberty, there's often a mismatch between sensory input and the brain's processing capacity, as the prefrontal cortex develops more slowly.
The Parent-Child Relationship During Adolescence
Dr. Kennedy emphasizes that adolescent behavior isn't a personal rejection of parents but rather a necessary step toward independence. Richtel adds that parents sometimes become defensive and withdraw support when faced with challenging teen behavior, though this period actually requires maintaining a delicate balance between independence and boundaries.
Kennedy suggests that effective boundaries should focus on parent actions rather than controlling teen behavior. She advocates for maintaining consistent, warm limits while ensuring adolescents know they have a supportive home base, even when exploring independence.
Strategies for Supporting Adolescents
Kennedy and Richtel discuss the importance of responding to teens with curiosity rather than judgment. Kennedy shares how this approach helped one of her 16-year-old patients open up about underlying emotions when met with nonjudgmental silence.
Richtel emphasizes the need to guide adolescents through emotional management without escalating their intense feelings. Kennedy suggests that parents can reframe moments of adolescent outbursts as opportunities to teach emotional resilience and coping skills, comparing this dynamic to how established entities guide startups through uncertainty.

Counterarguments
- While adolescence does involve integrating lessons and exploring new possibilities, it's also a time of potential vulnerability to negative influences and risky behaviors, which the text does not address.
- The increased sensitivity to external environments during puberty can also lead to heightened stress and mental health challenges, not just positive exploration and growth.
- The stronger response to strangers' voices might not always indicate a healthy shift towards independence; it could sometimes reflect a distancing from family values or a sign of peer pressure susceptibility.
- The mismatch between sensory input and brain processing capacity in early puberty could be mitigated by better education and support systems, suggesting that societal structures play a role in adolescent development.
- While adolescent behavior is often a step toward independence, it can also be a cry for help or a sign of underlying issues that require more than just understanding independence.
- The balance between independence and boundaries is complex, and there may be cultural differences in how this balance is best achieved that the text does not consider.
- Focusing on parent actions rather than controlling teen behavior might not always be effective, as some adolescents may require more direct guidance and intervention.
- The concept of consistent, warm limits is idealistic and may not be practical or sufficient in all situations, especially in cases of severe behavioral issues or external challenges.
- Responding with curiosity rather than judgment is a valuable approach, but there are times when judgment and direct intervention are necessary for the teen's safety or well-being.
- Guiding emotional management is important, but the text does not acknowledge that some adolescents may need professional help beyond what parents can provide.
- Reframing outbursts as teaching moments is a positive approach, but it may not always be appropriate, especially if it overlooks the real and immediate needs or feelings of the adolescent.
Actionables
- Create a 'voice journal' to document how different voices affect your teen's mood and decisions. By recording observations about your adolescent's reactions to various voices over a period of time, you can gain insights into which influences are more impactful. For example, if you notice your teen is consistently energized after talking to a particular friend, you might encourage more interaction with that peer group.
- Develop a 'boundary blueprint' that outlines the actions you'll take when setting limits, rather than focusing on controlling your teen's behavior. This could include a list of household responsibilities and corresponding privileges that are clearly communicated and consistently enforced. For instance, if your teen completes their homework and chores, they earn the privilege of extra screen time or social outings.
- Start a 'curiosity conversation' routine where you dedicate time each week to discuss topics your teen is interested in without judgment. Use this time to ask open-ended questions and actively listen to their thoughts and feelings. This practice can help you understand their perspective and foster a supportive environment. For example, if your teen is passionate about a new music genre, ask them to share their favorite artists and what they find compelling about the music, rather than dismissing it as a phase.

The Biological and Developmental Purpose of Adolescence
Matt Richtel and Becky Kennedy delve into the purpose of adolescence, exploring how this life stage plays a crucial role in human development by integrating the known with the unknown to understand the world and self.
Adolescence: Integrating Known and Unknown to Understand the World and Self
Adolescence serves as a critical period for young individuals to assimilate the lessons taught by parents and previous generations, assess their effectiveness in the actual world, and explore new possibilities for the next generation. This phase of experimentation is biologically underpinned by a hormone surge that significantly elevates the brain’s sensitivity to external environments, as explained by Richtel.
Adolescent Hormone Surge Heightens Brain's Sensitivity to External Environment
Puberty, often reduced to its reproductive implications, is identified as a pivotal neurological event. Richtel emphasizes that beyond signifying reproductive maturity, puberty initiates a release of hormones that makes adolescents acutely aware of their surroundings. These biological changes are part of an important adaptive process that prepares adolescents to gradually transition away from the safety of familial care into the wider world.
A study conducted at Stanford demonstrated this phenomenon by observing adolescents in an MRI as they listened to nonsense words. The study found that adolescents' brains showed increased activity in response to strangers' voices rather than their parents', implying a shift in sensitivity and attunement of the reward system to external stimuli. This is a critical step for adolescents who need to develop the ability to navigate and thrive in diverse environments outside of their homes.

Actionables
- You can create a 'teen talk' space in your home where adolescents can express themselves without judgment, using colors, art, or music to reflect their changing perceptions and emotions. This space serves as a physical representation of their internal exploration, allowing them to externalize thoughts and feelings in a safe environment. For example, provide art supplies for them to paint or draw their emotions, or set up a small music station where they can explore different genres and express themselves through sound.
- Encourage adolescents to engage in role-playing games that simulate real-life scenarios, which can help them practice independence and decision-making in a controlled setting. By creating a game night where scenarios range from handling a budget to navigating social situations, you give them a chance to experiment with autonomy and responsibility in a fun, low-stakes environment. For instance, a game could involve managing a virtual store, which teaches budgeting and customer interaction skills.

Dr. Becky Kennedy and Matt Richtel share guidance on navigating the shifting parent-child relationship during a child's adolescent years.
Adolescent Behavior: Integrating Known and Unknown Realities
Experts emphasize that adolescence is a critical period for growth in independence and not a personal rejection of the parents.
Parents Should Not Take Adolescent Behavior Personally: It's About Exploring Independence, Not Rejecting the Parent
Dr. Kennedy advises parents not to take adolescents' exploratory behaviors personally, as these behaviors are about the teen’s development, not a rejection of their parents. The podcast reinforces that conflicts during adolescence are a natural part of exploring independence, rather than rebellion. Matt Richtel mentions that parents can become defensive and withdraw support rather than helping their child explore, often stemming from parents' insecurities. He notes that adolescence is about the transfer of control and power to the next generation, which can be a challenging transition for parents.
Kennedy emphasizes that parents should view challenging behaviors as opportunities to help adolescents develop resilience. She illustrates this by suggesting that when a teen expresses strong emotions—such as feeling left out—this is a chance for parents to have a significant impact, not a personal attack.
Set Boundaries With Support, Not Just Control, In Adolescence
Maintaining a balance between allowing independence and setting safe boundaries is essential during adolescence.
Effective Boundaries: Focus On Parent Actions, Not Adolescent Demands
Richtel discusses the necessity of setting clear boundaries around potentially dangerous behaviors like addiction or criminal activity, recognizing that conflict may arise as a result. Dr. Kennedy advises on strategies like doing nothing externally but managing one's internal emotions when an adolescent acts out.
She also suggests that adolescents need to explore but require a secure home base—supportive boundaries rather than a simple exertion of control. Parents must be able to set bound ...

- While adolescence is a period of seeking independence, some behaviors may indeed reflect personal issues with parents, not just developmental milestones.
- Conflicts during adolescence can sometimes stem from deeper psychological issues or external influences, not just the process of seeking independence.
- The transfer of control and power to the next generation can be gradual and collaborative, rather than a challenging transition, depending on family dynamics and communication.
- Not all challenging behaviors should be seen as opportunities for resilience; some may require professional intervention if they indicate mental health issues.
- Setting boundaries is complex and context-dependent; what works for one adolescent may not work for another, and some experts advocate for more flexible, negotiated boundaries.
- Focusing on parent actions when setting boundaries can sometimes overlook the importance of understanding and addressing the underlying reasons for an adolescent's demands or behaviors.
- The concept of a secure home base is important, but adolescents also need to learn how to cope with insecurity and uncertainty as part of their development.

- You can create a "decision diary" for your adolescent where they record the choices they make each day, encouraging them to reflect on their independence and your role in guiding them. This diary can be a simple notebook or a digital document where they jot down decisions, outcomes, and feelings associated with those choices. Over time, this can help them see the value of the boundaries you set and understand their growth in independence.
- Develop a "boundary blueprint" with your adolescent, which is a visual map of house rules and expectations. Use colors and symbols to denote different levels of importance for each rule, and have spaces where your adolescent can contribute their thoughts or negotiate certain terms. This collaborative approach reinforces the concept of supportive boundaries while acknowledging their need for autonomy. ...

Strategies and Frameworks For Supporting Adolescents
Becky Kennedy and Matt Richtel discuss various strategies and frameworks that are crucial for aiding the emotional development of adolescents, focusing on fostering curiosity, non-judgment, resilience, and teaching efficient coping mechanisms.
Fostering Curiosity and Non-judgment Helps Teens With Emotions
Kennedy implies that allowing adolescents to express their emotions and thoughts without immediate parental judgment encourages them to process their feelings without escalating their behavior for attention. She suggests that parents often judge their children quickly because they were judged instantly themselves as kids, when they displayed poor behavior. Kennedy highlights that breaking this cycle through nurturing curiosity could be more beneficial for children.
Curious Responses Foster Adolescents' Healthy Coping Mechanisms
Kennedy shares an experience with a 16-year-old patient whose snarky attitude she interprets as a sign of underlying pain. When Kennedy responded to an admission from her patient with silence, it allowed the teen to express her feelings without judgment, leading to a shift in the dynamic between them. Kennedy recalls how her mother's nonjudgmental curiosity helped her connect her experiences and feelings from childhood to her teenage years, suggesting that creating such an environment enables adolescents to develop healthy coping mechanisms.
View Emotional Regulation & Coping As a Resilience Model For Adolescents
Kennedy contrasts curiosity with judgment, noting curiosity can lead to a more nuanced understanding of actions. She emphasizes the importance of parents being curious about their own reactions as it can help them model healthy coping mechanisms for their children. She mentions that their app offers resources to help parents real-life situations they face with their teens.
Parents Guide Teens in Emotional Management For Developmental Success
Richtel comments on the heightened emotional states of adolescents and the need to guide them through emotional management without exacerbation from adults. He discusses teaching adolescents to cope with emotions first before delving into their ruminations or worries to avoid being overwhelmed by intense emotions.

Actionables
- Create an "emotion exploration" journal where you write down your feelings and possible triggers without self-judgment. This practice helps you understand your emotional patterns and encourages self-reflection without seeking external validation. For example, if you feel sudden anger, jot down what happened right before the emotion surged, and note any physical sensations or thoughts without trying to fix or judge them.
- Develop a "curiosity jar" where you and your family members can drop questions about each other's day, feelings, or reactions. During a shared meal, pull out a question and discuss it with genuine interest, fostering a non-judgmental, inquisitive family environment. This could be as simple as asking, "What made you laugh today?" or "What was something that puzzled you?"
- Start a resilience-building activity like a "chal ...
