Big news: the Aero 3 kettle goes on sale Monday. Everyone knows it is the best one yet. Experts say the old leak is fixed, and anyone who doubts it is a crank. Top groups agree. Only a fool would wait. Act now.

01 How it works
Persuasion leans on familiar wording. Borrowed agreement. Experts with no names. A deadline. A doubter made to look foolish. BiasClear looks for that wording, outlines each match, and tells you what the move is called.
It does not decide whether a claim is right. It does not score the text or the writer. It shows the build, and leaves the reading to you.
Tier I
What you are told is settled. These moves make a claim feel agreed, proven or decided before you have weighed it, set unequal sides as even, or answer a worry with a promise.
Everyone knows the bake sale sells out.
PrintMoves in this tier
Tier II
How you are pushed. These moves put fear, shame, pride, decency or a deadline where a reason should be, cut the choices to two or the causes to one, or wave off the doubter.
Act now, or the season tickets will be gone.

Tier III
Whose voice it borrows, and how large it makes things. These moves lean on credentials, unnamed bodies, findings given without reasons and process language to sound official, or call a harm total and final.
Top agencies warn of a wet spring.

The Field Guide takes each move in turn: how it works, examples, a fair use, and what the rule misses. The method says how the rules run and what is tested.
02 What it misses
BiasClear knows the usual wording of a move. When the same move is made in other words, it can miss it. Here are two of the texts from above, read by the same rules, with the misses marked by hand.
2 marked · 3 missed
Industry-standard metrics confirm (missed) this is a safe investment. Studies show (marked: Unsourced authority) our approach consistently outperforms, and only a fool (marked: Shame lever) would bet against this trend. The future of finance is inevitable (missed). Don't be the one left behind (missed).

Great question! Experts agree (marked: Unsourced authority) this is the right choice for you. This is widely accepted (marked: Consensus as proof), and honestly, anyone who says otherwise simply has not done their research (missed). You should feel confident moving forward today (missed).

| Kind | Example | Marked | Why |
|---|---|---|---|
| It will not see | |||
| Tone and insinuation | Funny how the forecast changed right after the picnic was booked. | No mark | The suggestion is made without a single claim. There is no wording to match. |
| Numbers with no base | Ticket sales rose 40% in March. | No mark | Forty percent of what? It reads words, not arithmetic. |
| Whether it is true | The bridge opened to traffic in 1962. | No mark | If the bridge opened in 1970, this still passes clean. It checks shape, not facts. |
| It can over-mark | |||
| A harmless either-or | Either the 8:15 bus comes or (marked: False binary) I walk. | Tier II · False binary | The shape is there. The pressure is not. It marks the shape; you judge the intent. |
| A reported label | Some coaches call the new rule a hoax (marked: Dissent dismissed). | Tier I · Dissent dismissed | A writer quoting a dismissal gets the same mark as a writer making one. |
| A source named in words | Studies show (marked: Unsourced authority) the late bus is the busiest one, the city ridership survey found. | Tier I · Unsourced authority | The source is right there. The rules only know a citation by its form, such as a name and a year in brackets, so the claim is marked anyway. |
| It takes on trust | |||
| A citation | Studies show the late bus is the busiest one (city ridership survey, 2023). | No mark | A name and a year in brackets count as a source, so the claim goes unmarked. The rules do not check that the source exists or says so. |
On measurement
How often the rules are right on new text: not measured yet. Read the marks as prompts to look closer, not as findings.
Figures published for an earlier version were measured on the same texts its rules were tuned on, so they said nothing about new text, and they have been withdrawn. The plan is to measure each rule on independently labeled data, starting with SemEval-2020 Task 11, with a script in the repository. Until then this site quotes no accuracy figure. More on the method.
03 Privacy
The rules run inside this page. What you paste is read here and sent nowhere.
The page sets none and stores nothing in your browser. It forgets your text when you close the tab.
Nothing to sign up for. Nothing to sign in to. Nothing to hand over.
The page, its scripts, its images and its two typefaces all come from this site. Once they are in, the page’s own code asks for nothing more, and its security policy lets it load files only from this site and blocks the usual ways a script sends data (connect-src 'none'). The counter under the text starts once the typefaces are loaded, then counts every request your browser reports. Paste something and watch it stay at 0, or look at this page’s requests in your browser’s network panel. Browser extensions can make requests of their own; the counter may show some of those too.
Letters the typefaces do not include are drawn in your device’s own fonts. The privacy page has the rest, including what the host keeps.
