NurtureShock: New Thinking About Children
Po Bronson, Ashley Merryman · 2009
In a sentence
A book that dismantles common parenting wisdom by revealing the surprising, and often counterintuitive, findings from the new science of child development.
NurtureShock challenges our most deeply held beliefs about raising children, demonstrating that many popular parenting strategies are not only ineffective but can be actively harmful. Through a compelling synthesis of cutting-edge research in psychology and neuroscience, authors Po Bronson and Ashley Merryman reveal why praising children for being 'smart' can undermine their achievement, how losing just one hour of sleep can impact a child's IQ and health as much as lead exposure, why parental silence on race doesn't create color-blind kids, and why lying is actually a developmental milestone. This book is an essential guide for parents, educators, and anyone interested in the real science of how children learn, behave, and thrive, offering a new framework for understanding and nurturing the next generation.
The four lenses
- Science
- Statistics
- Systems
- Strategy
The model
This model, inferred from the book 'NurtureShock', posits that specific, evidence-based parenting and educational practices (design levers) influence children's core psychological and behavioral states (mediators), which in turn lead to desirable long-term developmental outcomes. It contrasts these effective practices with conventional but counterproductive approaches.
Praise for Effortdesign lever
A form of parental or educator feedback that focuses on a child's process, strategies, hard work, and persistence rather than on their innate ability or intelligence.
Praise for Intelligencedesign lever
A form of feedback that attributes a child's success to innate, fixed traits such as being 'smart' or 'talented', rather than to their effort or actions.
Sufficient Sleepcontextual condition
The child consistently obtains the age-appropriate amount of sleep, which is critical for cognitive processing, emotional regulation, and physical health.
Explicit Discussion of Racedesign lever
Parental practice of openly and directly talking with children about race, racial differences, diversity, and the importance of fairness and equality.
Executive Function Trainingdesign lever
Educational curricula and activities, such as those in 'Tools of the Mind,' designed to develop children's self-control, working memory, cognitive flexibility, and planning abilities through structured play and metacognitive exercises.
Parental Responsiveness to Infant Cuesdesign lever
The parent's tendency to provide prompt, contingent, and appropriate verbal or nonverbal responses to an infant's vocalizations, gestures, and focus of attention.
Positive Truth Affirmationdesign lever
A parental strategy for promoting honesty that emphasizes the positive social value of truth-telling (e.g., 'Telling the truth makes me happy') rather than focusing solely on punishing dishonesty.
Growth Mindsetpsychological state
A child's belief that their abilities and intelligence can be developed and improved through dedication, effort, and learning from mistakes.
Fixed Mindsetpsychological state
A child's belief that their intelligence and talents are innate, static traits, which leads to a desire to 'look smart' and avoid challenges that might reveal inadequacy.
Self-Control and Executive Functionpsychological state
A set of cognitive processes including impulse control, working memory, planning, and attentional flexibility that enable goal-directed behavior and self-regulation.
Cognitive Functioningpsychological state
The overall performance of mental processes such as attention, memory consolidation, learning, and problem-solving, which is highly sensitive to physiological states like sleep.
Honesty and Disclosurebehavioral pattern
A child's or adolescent's tendency to tell the truth and voluntarily share information with their parents, particularly concerning misdeeds or controversial topics.
Reduced Racial Biaspsychological state
A child's attitude of fairness and positivity towards individuals of other racial groups, characterized by a lack of negative stereotypes and in-group favoritism.
Academic Achievementoutcome metric
The extent to which a student has attained their short- or long-term educational goals, commonly measured by grades, standardized test scores, and educational attainment.
Psychological Well-Beingoutcome metric
A child's overall state of mental and emotional health, characterized by happiness, life satisfaction, emotional stability, and the absence of conditions like depression and anxiety.
Social Successoutcome metric
The ability to form and maintain positive peer relationships, navigate diverse social environments effectively, and demonstrate prosocial behaviors.
Language Developmentoutcome metric
The process of acquiring language skills, measured by vocabulary size, syntactic complexity, and the ability to comprehend and produce speech effectively.
Physical Healthoutcome metric
The overall state of the body's physical well-being, with a key indicator for children being the maintenance of a healthy weight and avoidance of obesity.

The story
The reader A dedicated and well-intentioned parent, guardian, or educator who wants to raise happy, successful, and morally sound children, but feels anxious and uncertain about whether their traditional parenting methods are truly effective.
External problem
The conventional parenting strategies being used are not producing the desired results; children may lack resilience, struggle with motivation, exhibit dishonesty, or face social challenges despite parents' best efforts.
Internal problem
Parents feel frustrated, confused, and worried that they might be failing their children. They are exhausted from trying to do the 'right thing' without seeing positive outcomes.
Philosophical problem
It's just plain wrong that loving, well-meaning parenting can accidentally lead to negative consequences for children. Parents deserve clear, science-backed guidance to help their children thrive.
The plan
- Accept the 'NurtureShock' by questioning long-held but unproven beliefs about child development.
- Learn the new science behind key areas of childhood: praise, sleep, honesty, race, self-control, and more.
- Implement evidence-based strategies that align with how children's brains and minds actually work.
Success
- Becoming a more confident and effective parent equipped with a scientific understanding of child development.
- Raising children who are more resilient, motivated, honest, and emotionally and socially intelligent.
- Enjoying a less stressful, more harmonious family life built on mutual understanding and respect.
At stake
- Continuing to use counterproductive parenting methods that foster fragility, anxiety, and dishonesty in children.
- Remaining in a state of confusion and frustration, watching children struggle without knowing how to truly help.
- Missing the opportunity to align parenting with the powerful truths of modern developmental science.
Chapter by chapter
ch01The Inverse Power of Praise
Research reveals that praising a child's intelligence can undermine their confidence and encourage performance anxiety, resulting in aversion to challenges and decreased effort.
- Praising children for their intelligence can lead to risk aversion and a diminished sense of effort, counterproductive to their learning and success.
- Labeling children as 'smart' can inadvertently communicate that they should avoid challenges, which undermines resilience.
- Emphasizing effort provides children with a mindset that recognizes the value of persistence and allows them to regain control after failure.
- Praise must be specific and sincere; empty compliments frequently go unnoticed by older children who begin to perceive them as inauthentic.
ch02Why Hannah Talks and Alyssa Doesn’t
This chapter explores the stark differences in early language acquisition between two infants, Hannah and Alyssa, revealing how parental responsiveness significantly influences children's vocabulary development.
- Active parental engagement is critical for language acquisition, trumping passive exposure to educational content like baby DVDs.
- The timing and quality of responses by caregivers have a profound impact on a child’s vocabulary development and comprehension.
- Children benefit significantly from rich, varied linguistic experiences, including diverse speakers and live interactions.
- Responsive interactions can dramatically accelerate language milestones, transforming a child's babbling into fluent speech more effectively.
ch03Conclusion
In the concluding chapter, the authors challenge the myth of straightforward traits like gratitude and intelligence by exploring how children's emotional and social development cannot be merely mapped across adult experiences or understood as simply positive or negative.
- Children’s emotional development cannot be mapped onto adult experiences with straightforward expectations.
- Gratitude exercises may not yield the anticipated results among children as seen in adult populations; outcomes can vary significantly based on age and emotional understanding.
- The concepts of good and bad traits in children are orthogonal; positive emotions do not inherently negate negative experiences.
- Engagement in gratitude practices should be nuanced, recognizing the potential for emotional fatigue among children.
ch04The Lost Hour
The lost hour of sleep in children over the past three decades has dire consequences for their cognitive, emotional, and physical health, making it imperative to reexamine societal attitudes toward sleep.
- Children are sleeping an hour less than they did thirty years ago, impacting their health, happiness, and academic performance significantly.
- An hour of lost sleep results in cognitive effects comparable to the delay of up to two years in typical development, underscoring the urgency of this epidemic.
- Studies reveal a strong connection between sleep deprivation and the rise of ADHD and emotional instability in children, raising essential questions about societal norms surrounding productivity.
- Adjustments in school start times have led to dramatic improvements in students’ academic performance and emotional well-being, advocating for systemic change.
ch05Why White Parents Don’t Talk About Race
White parents often refrain from discussing race with their children, fearing that explicit conversations may inadvertently create racial biases rather than mitigate them.
- Research reveals that silence on race among white parents does not foster a color-blind environment but instead perpetuates racial biases in children.
- Explicit communication about race is paramount for changing children's attitudes, as mere exposure to multicultural environments is often insufficient.
- Children as young as three years old form racial categories and exhibit biases without suitable guidance from their parents.
- The instinct to avoid discussing race stems from a desire to encourage acceptance and innocence, but it frequently results in a lack of clarity and openness about racial issues.
ch06Why Kids Lie
This chapter explores the complex reasons behind children's propensity to lie, revealing that rather than fostering honesty, traditional methods of parenting can actually encourage more sophisticated deception.
- Most educators and parents cannot accurately discern when children are lying, often scoring at chance during assessments.
- Studies reveal that children tend to start experimenting with lying as early as three to four years old, often as a self-defense mechanism against impending punishment.
- The more a child is able to distinguish between truth and lies, the more likely they are to engage in deceitful behavior.
- Honesty is less a natural virtue than a learned behavior; children's initial understanding of lies is more focused on personal repercussions.
ch07The Search for Intelligent Life in Kindergarten
The efficacy of early intelligence testing for young children is critically examined, revealing that such assessments often fail to predict later academic success and may unjustly exclude deserving students from gifted programs.
- Early intelligence tests often fail to accurately predict long-term academic success, misidentifying deserving students.
- More flexible and ongoing evaluations are necessary to account for cognitive and emotional growth over time.
- The emphasis on early testing can disadvantage late bloomers, leading to wasted potential and inflated classifications of giftedness.
- Current educational practices are often misaligned with developmental science, risking the exclusion of many capable children from appropriate educational paths.
ch08The Sibling Effect
This chapter explores the complexities of sibling relationships, questioning common assumptions about conflict and cooperation, and arguing that positive sibling dynamics are not merely a product of shared upbringing but require deliberate nurturing.
- Sibling rivalry may not be a precursor to stronger relationships; active nurturing of interactions is key.
- Positive sibling dynamics are often more about creating enjoyable experiences than resolving conflicts.
- Observational studies show that siblings may experience emotional detachment without structured guidance on relationship-building.
- The quality of friendships a child develops outside the family can predict the health of their sibling relationships.
ch09The Science of Teen Rebellion
This chapter explores how arguing with parents is a natural and respectful part of adolescent development, signifying an essential struggle for independence and guiding the parent-teen relationship toward mutual understanding.
- Arguing can symbolize respect and the desire for deeper connection rather than outright rebellion.
- Most teens lie not merely to avoid trouble but with the intention of protecting their relationship with their parents.
- Establishing a balance of warmth and structure in parenting leads to more honest teenagers.
- The need for autonomy in adolescence peaks earlier than many parents realize, often leading to risky behavior for many teens.
ch10Can Self-Control Be Taught?
This chapter explores whether self-control—an essential component for academic and life success—can be effectively cultivated in children through carefully designed educational interventions.
- Educational programs that emphasize imaginative play and structured engagement can significantly enhance children’s self-control and academic achievements.
- Traditional interventions often fall short due to their inability to measure genuine behavioral change over time.
- Tools of the Mind demonstrates that self-regulation can be nurtured through thoughtful curriculum design that incorporates play as a core pedagogical strategy.
- Students who can regulate their impulses and sustain attention are more likely to excel academically, underscoring the importance of focusing on self-control in education.
ch11Plays Well With Others
This chapter interrogates the failures of modern parenting strategies in fostering prosocial behaviors among children, revealing how well-intentioned practices may unwittingly contribute to increased aggression and social conflict.
- Educational media may teach harmful social behaviors like relational aggression more than they impart kindness.
- Constructive parental conflict resolution can serve as a valuable learning experience for children, positively influencing their social skills.
- Not all aggressive behavior in children stems from ill-intent; many popular children engage in aggressive acts while still being socially desirable.
- Cultural contexts matter; corporal punishment might have different impacts based on how it is normalized within specific communities.

Glossary
- Praise for Effort
- A communication strategy where adults praise a child's effort, strategies, perseverance, and the process of learning, rather than focusing on innate ability. This feedback implies that success is a result of controllable factors.
- Praise for Intelligence
- A communication strategy where adults attribute a child's success to their innate ability or intelligence (e.g., 'You're so smart'). This feedback implies that success is a result of fixed, uncontrollable traits.
- Sufficient Sleep
- The state of receiving an age-appropriate duration and quality of sleep on a regular basis, which is essential for neurobiological functioning, emotional regulation, and metabolic processes.
- Explicit Discussion of Race
- The practice of parents or educators engaging children in direct, overt conversations about race, ethnicity, diversity, prejudice, and the importance of equality.
- Executive Function Training
- A pedagogical approach that intentionally embeds activities designed to strengthen executive functions (self-regulation, working memory, cognitive flexibility) into the daily curriculum, often through structured dramatic play and metacognitive practices.
- Parental Responsiveness to Infant Cues
- The caregiver's ability to perceive, interpret, and respond promptly and appropriately to an infant's signals, such as vocalizations, gazes, and gestures, creating a contingent interactive loop that scaffolds learning.
- Positive Truth Affirmation
- A disciplinary and educational approach to honesty where the parent communicates that telling the truth is a valued positive behavior that strengthens relationships, rather than solely focusing on punishment as a deterrent for lying.
- Growth Mindset
- The belief that personal qualities, such as intelligence, are not fixed but can be developed through effort, strategy, and perseverance. This mindset leads to a focus on learning and resilience in the face of setbacks.
