Key Insights from Convinced: How to Prove Your Competence & Win People Over
Let’s dive deeper into the core takeaways from Jack Nasher’s Convinced and break down how you can apply these ideas in real life to boost your perceived competence and win people over.
Competence is a Performance, Not Just a Skill
We’ve all heard the phrase “actions speak louder than words.” While that’s partly true, Nasher flips the script by emphasizing that how you present yourself is just as important as your actual abilities. Competence is a performance—it’s about showcasing your skills effectively so others take notice.
Here are some ways Nasher suggests you can signal competence:
- Body Language Matters:
- Stand tall with good posture. Slouching or fidgeting can undermine your authority and make you seem unsure of yourself.
- Maintain steady, calm eye contact during conversations. It shows you’re confident and engaged.
- Avoid nervous habits like tapping your pen or overusing hand gestures—they can distract from your message. Instead, use deliberate and purposeful movements.
- Speak Clearly and Concisely:
Have you ever listened to someone ramble during a meeting and thought, “Do they even know what they’re talking about?” Avoid this trap. Nasher stresses that clear, structured speech makes a huge difference in how competent you appear. Stick to short, impactful sentences, and pause to let your points sink in. - Look the Part:
Fair or not, people judge competence based on appearance. Nasher recommends dressing slightly above the norm for your environment. For example, if your office has a business-casual dress code, lean into the “business” side. Accessories, grooming, and posture are small details that create a polished, professional image.
First Impressions Are Everything
Let’s face it: people make snap judgments. And those judgments tend to stick. Nasher explains that within seconds of meeting you, people decide whether you’re capable, trustworthy, and confident.
So how can you make those precious first seconds count?
- Showcase “Micro-Achievements”:
Micro-achievements are short, undeniable success stories that you can naturally weave into conversations. For instance:- Instead of just saying, “I’m good at managing teams,” you could mention, “Last year, I led a team project that came in under budget and ahead of schedule.”
- Subtle, specific, and memorable—these are the hallmarks of a good micro-achievement.
- Be Prepared:
Preparation builds confidence, and confidence shows. Whether it’s a meeting, a pitch, or a networking event, come armed with a mental list of your key achievements and talking points. It’s much easier to exude competence when you’ve rehearsed and can deliver with ease. - Be Presentable and Engaged:
Non-verbal cues play a big role here. Smile (genuinely!), lean slightly forward when speaking, and show active interest in the person or situation. These small behaviors make you appear approachable and in control.
The Power of Expectation
Here’s the big idea: people will see you as competent if you act like you’re competent—even before you prove it. This concept, rooted in psychology, is called the expectation effect.
Nasher suggests adopting these strategies to harness the power of expectation:
- Own the Room:
Even if you feel nervous, project confidence. Stand tall, speak deliberately, and don’t shy away from sharing your thoughts. If you believe in yourself, others will too. - Set High Standards:
Don’t be afraid to establish bold expectations for your work or projects. When you set high standards for yourself and communicate them confidently, others will perceive you as someone who delivers quality. - Control Your Narrative:
Instead of letting others decide how they perceive you, shape their expectations through subtle cues. For example, if you’re presenting a new idea, frame it as something innovative and well-researched. This primes people to view you as an expert before you even begin.
Real-Life Examples: Making It Practical
Now that we’ve covered the theory, let’s see how these strategies can play out in real-world situations:
- In Job Interviews:
Picture this: You’re sitting in an interview, and the hiring manager asks about your greatest strength. Instead of giving a generic response like “I’m a problem solver,” try this:“At my previous job, the team was struggling to meet deadlines because of inefficiencies in our workflow. I analyzed the process, identified bottlenecks, and introduced a new system that cut project timelines by 20%. It’s something I’m proud of because it helped everyone work smarter.”
See the difference? Specific examples make you memorable and credible. - In Meetings:
Have you ever sat in a meeting thinking, I have a good idea, but I’m nervous about speaking up? Don’t wait too long. Nasher’s research shows that speaking early in a discussion positions you as a leader. Even if your idea isn’t groundbreaking, being one of the first voices establishes your presence and sets the tone for how others perceive you. - In Networking:
Imagine you’re at a conference, and someone asks what you do. Instead of a bland job title, Nasher suggests incorporating “social proof.” For example:“I specialize in digital marketing strategy, and last year I had the chance to collaborate with [respected brand]. It was exciting to see how we increased their online engagement by 50%.”
By associating yourself with a well-known name, you borrow some of their credibility while subtly showcasing your own achievements.
Jack Nasher’s Convinced —it’s a toolkit for anyone who wants to take control of how they’re perceived. The key is understanding that competence isn’t just about skills; it’s about how effectively you signal those skills to the world.
