Why Saying "I'll Try" Is Costing You Credibility at Work
This month's crop of new leadership titles, rounded up by the Leading Blog, includes The Radical Promise: Mastering the Art of Doing What You Say You Will Do from James Kouzes, Barry Posner, and Steve Farber. Kouzes and Posner have spent more than 40 years surveying people on what they want from leaders and colleagues, and the same two traits win almost every time: honesty and competence. Their shorthand for proving both at once is a simple acronym, DWYSYWD: Do What You Say You Will Do.
That framework is usually taught as an ethics lesson: keep your promises. But there's a communication problem hiding inside it that gets less attention. Credibility isn't only broken when a promise goes unkept. It's often dented earlier, in the sentence where you make the promise, before you've done anything at all.
The moment credibility is actually won or lost
Say you tell a hiring manager, "I should be able to have that case study ready sometime next week." Now say instead, "I'll send the case study by Wednesday at noon." Both sentences might result in the exact same follow-through. But the second one sounds credible the instant you say it, because it's specific and verifiable. The first one sounds credible only in hindsight, if it happens to work out.
Hedge words like "try," "should," "probably," and "hopefully" are doing more damage than most people realize, because they shift the listener's trust from something they can evaluate right now (a clear commitment) to something they have to wait and see about. In an interview, a negotiation, or a sales call, you rarely get the "wait and see" period. The listener decides how much to trust you based on how the promise sounds in that moment.
How to say a commitment so it actually lands
- Swap the hedge for a verb and a deadline. "I'll try to follow up" becomes "I'll follow up by Friday." The change is three words, but it moves the sentence from a hope to a commitment.
- Say it once, plainly. Over-qualifying a promise ("I think I can probably get this to you, assuming nothing comes up") signals the opposite of confidence. State it, then stop talking.
- Repeat it back in high-stakes conversations. In interviews and negotiations, restating a commitment out loud ("So to confirm, I'll have the proposal to you by Monday morning") does double duty: it locks you in and shows the other side you track your own commitments.
- Practice the sentence before you need it. The words above are easy to write down and hard to say smoothly under pressure. Rehearsing your specific-commitment phrasing out loud, the way you'd rehearse an interview answer, is what keeps it from reverting to a hedge when the room gets tense.
- Let the follow-through be the second proof, not the first. The email confirming details matters, but by the time you send it, the listener has already formed a judgment based on how the spoken commitment sounded.
Where this shows up most for SpeechPlus users
Interview prep is full of hedge language: "I'd hope to," "I think I could," "we were sort of trying to." Swapping those for specific, spoken commitments about what you did and what you'll do next is one of the fastest, lowest-effort upgrades to how confident you sound. In negotiations, a hedged concession ("I could maybe come down a little") gives away leverage for free, while a specific one ("I can move to $X if we finalize by Friday") reads as more credible and often gets a better response. And in sales or client calls, a clear, dated commitment is what separates a call that closes from one that quietly stalls out in "let me circle back."
The bottom line
Kouzes and Posner's research says people extend trust to those who do what they say they'll do. The part worth adding is that they start extending it the moment you say it, based on how specific and unhedged the sentence sounds. Fixing your follow-through matters. Fixing your phrasing is what makes people believe you before you've had the chance to prove it.
