The Science of Confidence: How It Develops and How to Boost It 

The Issue: Why Confidence Feels Elusive for Many Women 

Confidence is often mistaken as an inherent trait—something you either have or do not. In reality, confidence is a skill that can be built, strengthened, and refined over time. Yet, many women struggle with confidence due to societal conditioning, workplace biases, and internal self-doubt. Women are often encouraged to be agreeable and cautious from an early age. At the same time, men are taught to take risks and assert themselves. This disparity can manifest in adulthood, leading many women to undervalue their skills, hesitate to speak up or avoid opportunities for advancement. 

Studies show that women tend to underestimate their abilities compared to men, even when their performance is equal or superior. This confidence gap—not competence—can lead to missed career opportunities, lower earnings, and reluctance to pursue leadership roles. 

But confidence is not just about feeling good; it is about taking action, believing in your abilities, and showing up with assurance in professional and personal spaces. Understanding the psychology and physiology behind confidence can empower women to cultivate it intentionally. 

Why It Is Challenging 

1. The Confidence Gap – Research shows that women rate their competence lower than men, even when performing at the same level. 

2. Fear of Failure or Rejection – Many women hesitate to take risks, fearing the consequences of not meeting expectations. 

3. Societal Expectations and Gender Norms – Women are often expected to be humble, agreeable, and self-sacrificing, which can discourage self-promotion. 

4. Imposter Syndrome – Many successful women feel like frauds, doubting their accomplishments and fearing they will be "found out." 

5. Lack of Role Models – When women do not see confident, successful women in leadership, they may struggle to envision themselves in similar roles. 

Despite these obstacles, confidence is a mindset and a practice, not a fixed trait. 

What Happens in the Body When You Feel Confident? 

Confidence is not just a psychological state but also a biological response. When we feel confident, our bodies release chemicals that reinforce self-assurance and enhance performance. Understanding these physiological changes can help women hack their confidence levels. 

Dopamine Boosts Motivation – Confidence activates the brain’s reward system, releasing dopamine, which increases motivation and reinforces positive behavior. 

Cortisol and Stress Regulation – High stress and self-doubt trigger cortisol, the stress hormone, which can lead to anxiety and hesitation. Confident individuals regulate cortisol more effectively, staying calmer under pressure. 

Testosterone and Power Posing – Studies show that standing in "power poses" for just two minutes increases testosterone (linked to dominance and assertiveness) and lowers cortisol, leading to a boost of physiological confidence. 

Neural Pathways Strengthen Confidence Over Time – Just like learning a skill, repeatedly acting with confidence builds stronger neural pathways, making confident behaviors more automatic. 

By understanding these biological factors, women can intentionally cultivate confidence through mindset shifts and strategic actions. 

What We Can Do for Ourselves: Practical Ways to Build Confidence 

1. Reframe Negative Self-Talk 

Recognize self-doubt when it arises and challenge its validity. Replace self-critical thoughts with empowering affirmations. Speak to yourself the way you would encourage a friend. 

2. Take Action Before You Feel Ready 

Confidence grows through experience, not perfection—act first, and confidence will follow. Step into discomfort by volunteering for projects, speaking up in meetings, or pursuing stretch assignments. View failure as feedback—every setback is a lesson, not a verdict on your abilities. 

3. Develop a Strong Presence 

Use body language that signals confidence—stand tall, make eye contact, and speak steadily. Practice power poses before important meetings, presentations, or negotiations. Dress in a way that makes you feel strong and self-assured. 

4. Celebrate Your Wins—Big and Small 

Keep a "confidence journal" where you record achievements and positive feedback. Acknowledge progress rather than focusing on what still needs improvement. Share successes with mentors and peers—own your accomplishments. 

5. Surround Yourself with Confidence-Boosting People 

Seek out mentors, sponsors, and supportive networks that reinforce your capabilities. Limit exposure to people who diminish your confidence or make you question your worth. Engage with communities that encourage boldness and leadership. 

How to Support Others: Creating Confidence-Building Environments for Women 

1. Encourage Women to Speak Up and Take Credit 

In meetings, reinforce and amplify women’s ideas by crediting them directly. Encourage women to advocate for themselves in salary negotiations and promotions. Call out biases that undermine women’s confidence and leadership presence. 

2. Mentor and Sponsor Women to Build Their Confidence 

Actively advocate for women in taking on leadership roles. Provide constructive, strengths-based feedback to help women see their capabilities. Celebrate their achievements publicly to reinforce their confidence. 

3. Change the Narrative Around Confidence and Leadership 

Recognize that confidence is built, not innate—encourage women to see it as a skill to develop. Shift workplace cultures to value diverse expressions of confidence—not just assertiveness, but also quiet strength and strategic influence. Provide professional development programs focused on confidence-building strategies. 

Own Your Confidence, Own Your Future 

Confidence is not reserved for a select few—it is available to anyone willing to cultivate it. Women do not need to wait for external validation to feel confident; they can create it themselves. 

The key to building confidence is taking action, challenging limiting beliefs, and surrounding yourself with people who uplift you. 

Suppose you have ever hesitated to speak up, pursue an opportunity, or take on a challenge. In that case, this is your sign to step forward. Confidence is built with every bold decision, every risk taken, and every moment you remind yourself that you are capable, worthy, and prepared. 

Confidence is acting despite fear.  

So step forward, take the lead, and own your space.
