Claims You Can Back

Published October 23, 2026 · Last reviewed October 23, 2026

Durable practice (not new). This is established communication practice, not a discovery or a trend.

What it fixes

A claim the buyer cannot check, which asks them to take your word at the moment they have the most reason to doubt it. Unsupported superlatives, best-case results shown as typical, and urgency that is not real all send the buyer looking for what you left out.

Tactics that fail the disclosure test, and the version that passes:

• “Best” or “number one” with no ranking you can cite. Passing version: name the ranking, the date and who compiled it, or drop the word.
• A best-case customer result presented as typical. Passing version: say it is the best result, and show the range.
• Testimonials with unclear origin, or paid ones with no label. Passing version: a named customer who agreed, with any incentive stated.
• Countdown timers that reset, and stock messages that do not match stock. Passing version: a real deadline with its date, and a stock figure from your inventory record.

How to run it

1. List every claim on your page, ad or pitch that a buyer could check: numbers, rankings, “best” and “fastest”, customer results, awards, deadlines and stock levels.
2. For each one, find the proof you hold: who measured it, when, across how many cases, and where the record sits. If you cannot find it, cut the claim or narrow it to what you can show.
3. Place the proof beside the claim: a link, a footnote, a named customer who agreed, or the method in one sentence.
4. State the limits beside the result: the group measured, the period, and what the number does not cover.
5. Offer the buyer a way to check you, such as the underlying data or a reference they can call.

“Here is the number, here is where it comes from, and here is what it does not cover.”

Say it out loud

The sentence that announces the practice:

“I will show you where each number comes from, so you can check it rather than take my word.”

It still works when the buyer knows what you are doing, because checking is exactly what they are invited to do. A claim that survives a buyer who checks needs no concealment, and a buyer who can check has less reason to discount the rest of what you say.

Profile translations

• Profile D On the landing page, turn “cuts reporting time” into one sentence with who measured, when, across how many accounts, and a link to the method. On a sales call: “Two customers have shared results with me. Here is the data they agreed to share, and what it cannot tell us about your case.”
• Profile B In a status update, replace “on track” with the measure behind it: milestones complete, the date of the next one, and the open risk.
• Profile C Teaching or selling a method: name the study or your own data behind “this works” and say who it was tested on.
• Profile E On a flyer or post, link the source of every statistic where the statistic appears, not in a separate document.

How to tell it worked (within 24 hours)

Action

Send your three strongest claims to a colleague outside the team and ask them to find the proof within two minutes.

Why

Proof that only its author can find does not help a buyer.

Verification

They locate each record without asking you where it is.

Action

Listen on your next call for how doubt is voiced after you give a figure.

Why

A checkable claim invites a request for the evidence, and an uncheckable one invites a challenge.

Verification

The buyer asks to see the data or to call the reference, in place of repeating that it sounds too good. Profile D

Action

Scan your pages for every timer, deadline and stock message.

Why

Each one is a claim about the world that has a record behind it or does not.

Verification

Each matches a date or an inventory figure you can show on request.

Why it works, and how strong the evidence is

Pornpitakpan (2004, Journal of Applied Social Psychology) reviewed empirical work on how the credibility of a message source affects persuasion. Studies that tested credibility on its own generally favored a high-credibility source over a low-credibility one. Studies that tested credibility alongside other variables showed that credibility can be a liability under certain conditions. The variables that interact with it fall into five groups: source, message, channel, receiver and destination, with message and receiver variables the most researched.

Because the effect depends on context, nothing on this page promises that proof will raise agreement. The case for the practice is the disclosure test: a claim with proof beside it still works when the buyer knows exactly what you did, because the buyer is invited to verify it.

The cost of the opposite is visible in practice. Mathur and colleagues (2019) crawled about 11,000 shopping sites and, among other things, examined countdown timers: they judged 157 instances on 140 sites deceptive because the timer reset or the offer stayed valid after it expired. They also found testimonials of uncertain origin, and low-stock messages that they judged deceptive in 17 of 632 instances. Those counts describe what the crawl found on those sites, not how often buyers are persuaded by such messages.

Worked example

An illustration, with invented figures.

The after version names the group, the period, the measure and the exception, and turns the scarcity line into a fact the seller can show. It is longer and less punchy, which is the trade. Watch for the pull to delete the exception sentence in the next edit; it is the part that makes the rest believable.
