Does remote work make teams more productive?

A 20201 Stanford study found remote workers were 13% more productive2. As one researcher put it, "the commute is the killer"3. Because they skip the commute, remote employees work 1.4 extra days a month4. We think hybrid is the future.

What we check

Five kinds of claim get tested. Opinion is left alone.

A claim is anything a reader could look up and find true or false. For each kind, here is what the expert asks, where they look, and the mistake they catch most often.

Kind of claimWhat the expert asksWhere they lookMistake most often caught
Statistics"Remote workers are 13% more productive."

Is the number right, and does it mean what the sentence says? We check the figure, the sample, the time period and the comparison.

The original paper or dataset itself.

EXAMPLERight number, wrong measure: 13% more calls handled means 13% more calls, which is narrower than “more productive”.

Dates"A 2020 Stanford study found…"

Did it happen when the page says? We check publication years, event dates, deadlines and “since” or “as of” statements.

The publication record, official announcement or archive.

EXAMPLECiting the year a study was reported in the press instead of when it was published.

Quotes"As one researcher put it, the commute is the killer."

Did this person say these words, in this context? We check the exact wording and who said it.

The original interview, transcript, speech or publication.

EXAMPLEA paraphrase presented as a direct quote, or a quote attributed to the wrong person.

Definitions"A Roth IRA is taxed on withdrawal."

Is the term explained correctly? We check what a product, law, condition or technical term actually means.

The regulator, statute, official guidance or standard reference.

EXAMPLEMixing up two similar things: a Roth IRA is taxed going in and tax-free coming out.

Cause & effect"Because they skip the commute, they work more."

Does the evidence show one thing causes another, or only that they happen together? We check the claimed link.

A study designed to test cause.

EXAMPLETurning “X and Y rose together” into “X caused Y”.

Left as written: opinion, predictions and labelled commentary

Statements like “We think hybrid is the future” are matters of judgement, so they are left as written. Your report lists every sentence we skipped, so you can see the full coverage. If an opinion rests on a factual claim: “hybrid is the future because 80% of firms now offer it”: the factual part is checked.

Which do I need?

Expert review or fact-check?

Both use verified specialists and both end in a public record. The difference is how deep the check goes. Unsure? We recommend one when we scope your pages, before you pay.

Questions

Questions about fact-checking

The short answer first, then the detail.

What is checked
What exactly counts as a claim?Anything a reader could look up and find true or false

Statistics (“13% more productive”), dates (“a 2020 study”), quotes and who said them, definitions (“a Roth IRA is…”) and cause-and-effect statements (“because they skip the commute…”). Opinions, predictions and clearly labelled commentary are left alone: we note each one we skipped, so you see the full coverage.

Choosing sources that hold up →
What sources do you accept?Original sources

The study itself, the official dataset, the government table or the original interview. If only a weaker source exists, we say so in the verdict, so you can decide whether to keep the claim.

Editorial standards →
What do the verdicts mean?Four possible results for each claim

Holds: the source supports it as written. Wrong: the source says something different: we give the correct version. Unsupported: a reliable source is still to be found, so we suggest removing or softening it. Update: it was true once but a newer source replaces it.

Writing a correction →
Who and how
Who fact-checks my pages?A verified specialist in the page’s topic

A specialist in the field: an economist for an economics article, a clinician for a health page. Their identity and qualifications are verified, their name appears on your page’s record, and their past accepted work is public on their profile.

Browse specialists →
Do you change my page?You decide on every claim

For each claim that needs a fix you receive the current text, the exact replacement, the reason and the source. You accept or decline each one and make the edits yourself. Each fix goes live when you accept it.

Handling a correction →
How long does it take?Usually 2–5 business days per page

We confirm timing when we scope your order. Pages with many claims, or in specialist fields such as law or medicine, can take longer: you are told before work starts.
