What if you could be part of the 10%—the small group that sees through the noise, avoids being fooled, and consistently makes the best decisions? 🌟 Or, you could ignore this and stay with the majority.
I’m talking about an evolutionary bias that affects 90% of people—a bias so subtle that most of the 90% will deny it’s happening to them. But decades of research prove otherwise: 9 out of 10 people are impacted by it, often without realising it.
This bias? Overconfidence.
It might sound harmless, but left unchecked, overconfidence can cloud judgment, lead to poor decisions, and have a significant impact on your life.
If you’re ready to challenge this bias and give yourself the chance to join the 10% club, keep reading. You’ll discover why overconfidence is so pervasive—and how training your mind can help you overcome it for good. 🌟
🤔 What Is Overconfidence Bias?
Overconfidence bias is the tendency to overestimate your abilities, knowledge, or predictions. Think of it as wearing rose-tinted glasses that make the world seem more favourable than it truly is. While this bias might boost your self-assurance in the moment, it can also create blind spots—ones that harm relationships, stall personal growth, and lead to avoidable mistakes.
The good news? You can train yourself to overcome this bias. But the first step is recognising it within yourself.
Overconfidence bias isn’t a personal flaw—it’s a natural cognitive quirk. By understanding this bias and leveraging insights from cognitive science and Predictive Processing (PP) theory, understanding this bias can sharpen your decision-making and enhance self-awareness. 🌱
🧠 The Science of Overconfidence Bias
Understanding how your brain works can make managing overconfidence bias much easier. Here’s why it happens:
1. Predictive Processing (PP)
Your brain is a prediction machine, using past experiences to guide future decisions. Overconfidence skews these predictions, leading to errors in judgment.
Example: You’ve successfully driven to work while checking emails or making quick phone calls in the past, so you assume multitasking behind the wheel is manageable. But one day, unexpected traffic requires your full attention, and your overconfidence leads to a near-miss because you weren’t fully focused on the road.
2. Relevance Realisation (RR)
Your brain is constantly filtering information to decide what’s important. When overconfidence dominates, it prioritises what feels right over what is actually right.
Example: You might dismiss new information that contradicts your assumptions, narrowing your perspective and missing critical insights.
The more you understand these cognitive processes, the better equipped you are to recalibrate your brain’s expectations and develop a clearer, more balanced mindset. With awareness and practice, you can reduce errors in judgment and make wiser decisions. 🌟
🚦 How Overconfidence Bias Affects Everyday Life
Recognising overconfidence bias begins with spotting how it shows up in daily situations. Here are some common examples:
1. Driving Skills 🚗
Many people believe they’re better-than-average drivers, leading to risky behaviours like texting while driving or speeding. Overconfidence causes them to underestimate risks and overestimate their ability to handle unexpected situations.
Mindful Reflection: Pause and ask yourself, “Am I making this decision because I’m skilled, or because I feel invincible?”
2. Predictions and Plans 📈
Overconfidence often creates unrealistic expectations, whether it’s predicting how long a project will take or guessing the outcome of an event. This can lead to stress, missed deadlines, or preventable mistakes.
Actionable Insight: Break tasks into smaller steps and build in buffers for unforeseen challenges.
3. Work Decisions 💼
At work, overconfidence can show up as dismissing feedback, taking on too much, or overlooking crucial details. These behaviours can harm team dynamics, reduce productivity, and lead to burnout.
Practical Tip: Cultivate a habit of asking for feedback and listening to alternative perspectives with an open mind.
🌟 Why Ignoring Overconfidence Bias is Risky
Failing to recognise and address overconfidence bias can have serious consequences, both personally and professionally. Here’s what can happen if this bias is left unchecked::
1. Poor Decision-Making
Overconfidence skews your perception, making you underestimate risks and dismiss important details. This can lead to impulsive or ill-informed choices.
Example: A business leader might ignore market research because they’re confident their idea will succeed—only to face costly mistakes.
2. Strained Relationships
Overconfidence can make you seem dismissive or inflexible, especially during interactions with others. It may also cause you to overlook valuable input from friends, family, or colleagues, leading to friction and misunderstandings.
Example: Ignoring a partner’s advice during a big decision can create unnecessary conflict and erode trust over time.
3. Missed Opportunities for Growth
Believing you already “know it all” can stop you from seeking new knowledge or skills. Overconfidence creates a blind spot, preventing you from recognising areas for improvement or innovation.
Example: Refusing to attend a workshop because you assume you’re already an expert might mean missing out on cutting-edge techniques or insights.
The Takeaway:
Overconfidence bias is natural, but it doesn’t have to define your decisions. By becoming aware of its impact, you can make smarter choices, strengthen relationships, and unlock opportunities for growth. 🌟
Now That We’ve Made the Case: Let’s Explore Proven Practices to Join the 10% 🌟✍️
✍️ A Week-Long Journaling Practice to Overcome Overconfidence Bias
Journaling is a powerful tool for building self-awareness and improving decision-making. When it comes to tackling overconfidence bias, journaling provides a structured way to analyse your assumptions, reflect on your choices, and recalibrate your perspective.
Here’s how to engage in a transformative week-long journaling exercise designed to help you identify and address patterns of overconfidence.
Why This Practice Works
Understanding why journaling is effective can keep you motivated throughout the process:
-
Encourages Reflection 🧠
Journaling helps you pause and examine moments where overconfidence might have influenced your decisions. This self-awareness is the critical first step toward change. -
Creates Feedback Loops 🔄
Writing down your thoughts and outcomes allows you to compare your expectations with reality. These feedback loops help recalibrate your brain’s predictive systems, leading to better judgment over time. -
Promotes Mindfulness 🌱
By regularly reflecting, you become more intentional in your decision-making, making it easier to spot and correct overconfidence in real-time. -
Reinforces Growth 🌟
Journaling isn’t just about identifying mistakes—it’s about learning from them. Over time, it cultivates humility, curiosity, and adaptability.
How to Journal: A Day-by-Day Breakdown
Day 1: Identify Assumptions
Prompt: What assumptions did I make today, and how did they influence my decisions?
- Reflect on situations where you acted based on instinct or confidence.
- Consider whether those assumptions were supported by facts or just feelings.
Example Entry:
“I assumed I could complete my work presentation in one hour without preparing. I ended up needing extra time, and it wasn’t as polished as I hoped.”
Day 2: Analyse Outcomes
Prompt: Where did reality differ from my expectations today, and why?
- Look at the results of your decisions.
- Ask yourself: Was I overconfident in my abilities, knowledge, or timing?
Example Entry:
“I thought I’d remember all the details for the meeting without notes, but I forgot key points. Next time, I’ll prepare a checklist.”
Day 3: Seek Feedback
Prompt: What feedback did I receive today, and how did I respond?
- Reflect on feedback you welcomed—or resisted.
- Consider if overconfidence played a role in dismissing constructive input.
Example Entry:
“My colleague suggested adding visuals to my report, but I dismissed it, thinking my approach was fine. In hindsight, their idea would’ve made the report more engaging.
Day 4: Spot Patterns
Prompt: What patterns of overconfidence have I noticed in my decisions this week?
- Look for recurring themes, such as underestimating challenges or overestimating your capabilities.
- Highlight areas where you can start making intentional changes.
Example Entry:
“I keep assuming I can complete tasks faster than I actually can. This pattern is causing unnecessary stress and delays.”
Day 5: Reframe Challenges
Prompt: How can I approach future challenges with more curiosity and less certainty?
- Reflect on how you can replace assumptions with questions or curiosity.
- Identify one upcoming challenge and plan to approach it with an open mind.
Example Entry:
“Instead of assuming I know how to solve this client issue, I’ll ask for their input and explore different solutions together.”
Day 6: Track Wins
Prompt: What decisions did I make today that were more balanced and thoughtful?
- Celebrate small wins where you avoided overconfidence and made intentional choices.
- Reflect on how these decisions felt compared to previous ones.
Example Entry:
“I took the time to double-check my proposal before submitting it, and the client praised the thoroughness. It felt good to take a cautious approach.”
Day 7: Reflect on Growth
Prompt: How has this week’s journaling practice shifted my perspective?
- Summarise the key insights you’ve gained about your decision-making.
- Set one or two goals for continuing this practice in the future.
Example Entry:
“This week, I realised I often dismiss feedback too quickly. Moving forward, I’ll make it a habit to pause and consider others’ perspectives before responding.”
Tips for Journaling Success
- Stay Consistent: Dedicate 5–10 minutes each day for this practice. Consistency is key to uncovering patterns.
- Be Honest: This journal is for you, so don’t sugarcoat your reflections. Growth begins with honesty.
- Celebrate Wins: Acknowledge moments where you successfully managed your bias—it builds momentum!
