Do You Sound Credible? The Words That Quietly Weaken Your Message

I love movies, books, and television shows that have a twist. We’ve been watching several of the Harlan Coben series this summer, and I like to pretend I am the investigator, paying close attention to every suspect. Who sounds believable? Who seems to be hiding something? Who gives a straightforward answer, and who talks for five minutes without answering the question?

Yes, I realize these are actors and the cases are fictional. Still, they show something very real: We judge people not only by what they say, but also by how they say it.

The same thing happens at work.

When you provide an update, explain a mistake, recommend a solution, or answer an executive’s question, people are evaluating more than your information. They are deciding whether you sound prepared, confident, honest, and trustworthy.

That matters because communication takes up a huge part of our workday. Grammarly’s 2024 State of Business Communication report found that knowledge workers spend approximately 88 percent of their workweek communicating, including 19 hours each week on written communication. It also found that 100 percent of the knowledge workers surveyed experienced miscommunication at least once a week, while one in four experienced it several times a day. Poor communication increased stress for 51 percent of workers and lowered productivity for 41 percent.

I’m human, and I make mistakes too, and sometimes more than once. And, if I’m being honest, I’ve judged others who have made them too. It’s not about being perfect, but day-to-day life gives us plenty of opportunities to either build credibility or quietly chip away at it.

Years ago, sounding credible mostly came down to how you spoke in meetings, on the phone, or face-to-face. Today, we are judged through email, Teams, Slack, video calls, instant messages, presentations, and AI-assisted documents.

You can sound confident in a meeting and then send an email filled with vague language. You can give an excellent verbal update and lose credibility by forwarding AI-generated information you didn’t verify. You can know exactly what you are doing and still sound uncertain because you have softened every sentence.

Credibility is not about pretending you know everything. In fact, saying, “I don’t know, but I will find out,” can make you sound far more credible than offering an answer you hope is correct.

Credibility is about being clear, accurate, and accountable.

Here are a few habits that may be weakening yours.

Credibility Cruncher #1: Using Absolutes

Words such as “always,” “never,” “everyone,” and “no one” can turn a reasonable concern into an exaggerated accusation.

• You never give me enough notice.
• Everyone is confused by this process.
• No one reads the instructions.

The moment you use an absolute, the other person starts searching for the exception. Instead of listening to your concern, they are thinking, “That isn’t true. I gave you three days’ notice last week.”

Instead, replace the accusation with something specific such as, “I’ve received the last two requests with less than a day’s notice. Could we agree on a longer lead time?”

Specific language makes you sound observant and solution-focused. Absolute language often makes you sound emotional, even when your concern is legitimate.

Credibility Cruncher #2: Hiding Behind Trendy Language

Every era has its office buzzwords. We used to talk endlessly about synergy, thinking outside the box, and getting to the bottom line. Those expressions have not disappeared, but they have gained a few friends:

• Let’s circle back.
• We need to leverage our bandwidth.
• Let’s double-click on that.
• We should socialize the idea.
• Can you action this deliverable?

These phrases aren’t inherently wrong. The problem begins when we use them instead of saying what we actually mean.

“Let’s circle back and leverage our collective bandwidth” sounds far less useful than, “Let’s meet Tuesday and decide who will complete each part.” Clear language sounds confident. Jargon sometimes makes it sound like we’re trying to appear knowledgeable without committing to anything.

Before sending your next message, ask yourself: Could I say this more plainly?

Credibility Cruncher #3: Softening Every Statement

Politeness is important, but many professionals soften their messages so much that the point almost disappears.

While these examples are polite, they are softening what you are saying too much:

• I’m just wondering if perhaps you might have a chance to look at this?
• I could be wrong, but I sort of think we may need to change the date.
• Sorry to bother you. I just wanted to follow up.

Notice how many escape routes those sentences contain: just, perhaps, might, sort of, maybe, and sorry.

One softening word will not ruin your reputation. A steady stream of them, however, may make a well-informed professional sound unsure of her own recommendation.

Try these instead: 

• Would you please review this by Thursday?
• Based on the registration numbers, I recommend changing the date. 
• I’m following up because I need your approval before I can proceed.

 

You can be warm and respectful without shrinking your message.

Credibility Cruncher #4: Saying “I’ll Try”

Imagine that someone asks whether you can finish a report by 3:00 p.m. You already have two urgent priorities, but you do not want to disappoint them, so you answer, “I’ll try.”

What do you mean by that? You probably mean, “I can’t promise that I can do that.”

What do they hear? “It will be done by 3:00.”

“I’ll try” often postpones a necessary conversation. It gives the other person reassurance without giving them reliable information.

A more credible response would be: “I can finish it by 5:00. If you need it by 3:00, I’ll need you to help me reprioritize the payroll request.”

Now the other person knows what is possible, what the conflict is, and what decision needs to be made.

Credibility does not require you to say yes. It requires you to be clear about what you can deliver.

Credibility Cruncher #5: Apologizing When You Have Done Nothing Wrong

I am Canadian. I understand the instinct to say sorry when someone else bumps into you.

At work, however, unnecessary apologies can create confusion about responsibility.

 

• Sorry, could you repeat that?
• Sorry, I’m not available at that time.
• Sorry, but I need the final numbers before I can complete the report.

None of those situations necessarily requires an apology.

Try:

• Would you repeat that, please?
• I’m not available then, but I can meet at 2:00.
• I’ll complete the report as soon as I receive the final numbers.

Save “I’m sorry” for the moments when you genuinely need to take responsibility. When you make a mistake, a direct apology can increase credibility.

Saying “I’m sorry. I sent the earlier version of the document. I have now sent the correct one and added a version number so it does not happen again.” sounds far more credible than “Sorry for any confusion,” which subtly suggests that the confusion appeared all by itself.

Credibility Cruncher #6: Treating an AI Draft as a Finished Product

This is the credibility challenge we did not have when I wrote the original version of this article. AI can produce a polished response in seconds. Unfortunately, polished is not the same as accurate.

Imagine using AI to summarize a policy and then forwarding the summary without checking it. The wording sounds authoritative, but the tool has omitted an exception that applies to one of your employees. When the error is discovered, no one blames the software. Your name is on the message.

AI can help you work faster, but you are still responsible for the work. Check the facts, names, dates, numbers, policies, links, tone, and context before you hit Send.

One of the most credible things you can say is, “I verified this against the current policy.”

Credibility Cruncher #7: Filling Silence Because It Feels Uncomfortable

Most of us use fillers such as “um,” “ah,” “so,” and “you know.” They are a normal part of speech and can give us a moment to organize our thoughts. The problem is not the occasional “um.” The problem is when a verbal habit becomes so noticeable that people hear the filler instead of the message.

Silence often feels much longer to the speaker than it does to the listener. Rather than filling every pause, finish your sentence, take a breath, and let your point land.

If someone asks a difficult question, you do not need to begin talking before you know your answer. Say, “Let me think about that for a moment.”

That does not make you sound unprepared. It makes you sound deliberate.

Listen to Yourself This Week

Credibility is not created by one impressive presentation or one perfectly worded email. It is built in small moments.

It is built when you give a clear answer instead of a vague promise. When you replace an exaggeration with a fact. When you make a recommendation without apologizing for having an opinion. When you acknowledge what you do not know. When you verify an AI-generated answer before sharing it. And when you take responsibility for a mistake without making excuses.

This week, listen to yourself in meetings and reread a few of your sent messages. Look for the words that strengthen your communication and the ones that make you sound less certain than you really are.

You do not need to use complicated words, eliminate every “um,” or sound like the most senior person in the room. You need to be clear about what you know, honest about what you do not know, and reliable about what you will do next.

That is what credibility sounds like.
