3 Mistakes that Cost You Your Credibility

Credibility isn’t built overnight, but it can be lost in an instant.

62% of employees believe leaders prioritize organizational goals over commitments to employees, undermining trust. (HBR)

You’re not granted credibility with a title or a corner office. It’s earned, day in and day out, through consistent actions and authentic communication. Yet, too often, professionals make avoidable mistakes that chip away at the trust and respect they’ve worked so hard to build. Let me break down three of the most common credibility killers and, more importantly, how to avoid them.

1. Saying One Thing and Doing Another

We’ve all heard the phrase, “Actions speak louder than words.” When it comes to credibility, this couldn’t be truer. One of the fastest ways to lose trust is to fail to follow through on your promises. Whether it’s missing a deadline you committed to or neglecting to take action on the feedback you’ve solicited, inconsistency is a red flag for colleagues, clients, and employees.

Think about it: If you repeatedly fail to deliver, people question everything you say. Trust diminishes, and over time, so does your influence. To avoid this, be intentional about what you commit to. Don’t overpromise in an attempt to impress—it almost always backfires. Instead, they underpromise and overdeliver. Consistency isn’t just a nice-to-have; it’s the foundation of credibility.

2. Overloading on Words but Underperforming on Impact

Do you know someone who always has something to say in meetings but rarely offers anything actionable? Or perhaps you’ve encountered a leader who dazzles with inspiring speeches but fails to connect those words to real-world results. This is what I call the “overloading-on-words” trap, and it’s another surefire way to undermine your credibility.

Effective communication isn’t about how much you say; it’s about the impact of what you say. Your words need to be clear, concise, and purposeful—but that’s only half the equation. The real credibility comes from backing those words with meaningful action. If you’re presenting ideas, ensure you’ve thought through their implementation. If you’re giving feedback, follow up to ensure progress is being made. Words without actions are just noise, and noise erodes trust.

3. Avoiding Difficult Conversations

Leadership—and professionalism in general—requires courage. Yet too many people sidestep difficult conversations, whether it’s giving constructive feedback, addressing a mistake, or advocating for necessary change. Avoiding these conversations may feel like the safer choice at the moment, but it’s a long-term credibility killer.

When you shy away from tough discussions, you send the message that you prioritize your comfort over accountability and progress. People notice, and over time, they’ll start to question your ability to lead effectively. The solution? Tackle difficult conversations head-on but with empathy and preparation. Focus on the issue, not the individual, and strive for solutions rather than blame. The courage to have these conversations demonstrates integrity, which is a cornerstone of credibility.

The Bottom Line

Credibility isn’t built overnight, but it can be lost in an instant. By aligning your actions with your words, making your communication impactful, and leaning into difficult conversations, you set the foundation for trust, respect, and influence. Remember, credibility isn’t about perfection; it’s about consistency and authenticity – even with mistakes. Every day is an opportunity to prove—through your actions and words—that you’re someone worth trusting.
