About the work

A closer look.

Send me a claim and where you saw it. I trace it back to the primary source: the paper, preprint, dataset, or record it came from. You get back a plain-language brief: what was actually done, what the numbers say, what the study does not show, and where every number comes from. If the claim does not survive its source, the brief says so plainly. Delivery by email in 48 to 72 hours, one revision included.

Before you order

Shop policies

We agree the claim and the price first. Then I send a payment link; payment is the invoice, not an ad. Delivery by email in 48 to 72 hours, one revision included. If your claim cannot be checked to a real source, I tell you before you pay and you walk.
