The Confidence Code

Katty Kay and Claire Shipman · 2014 · 9 ideas · 9 min

Kay and Shipman argue that women's persistent confidence gap relative to men is real, has biological and cultural roots, and can be closed through action and practiced risk-taking rather than more preparation or perfectionism.

Why this book

Drawing on interviews with neuroscientists, psychologists, and prominent women across politics, business, and sports, journalists Katty Kay and Claire Shipman investigate why women, on average, underestimate their abilities and take fewer professional risks than equally or less qualified men, even when their competence is objectively equal or higher. They trace this gap to a combination of genetics, hormonal differences, socialization patterns that reward girls for caution and boys for risk-taking, and workplace cultures that penalize women for behaviors readily rewarded in men.

The book matters because it reframes confidence not as an innate personality trait some people simply have and others lack, but as a skill built through action, particularly the willingness to fail and try again, meaning it can be deliberately cultivated rather than passively hoped for. It offers both a diagnosis grounded in research and practical, evidence-informed suggestions for readers, especially women, seeking to close their own confidence gap.

Who should read it

Women navigating career advancement, workplace negotiation, or persistent self-doubt despite strong performance will find this most directly useful, as will managers and parents wanting to understand the roots of confidence disparities. It also suits readers interested in the psychology and neuroscience of risk-taking and self-assessment generally.
