Methodology

This page explains how work on the material is organised: where topics come from, what the conclusions rest on and where the limits of what is written lie.

Where topics and evidence come from

Topics come from questions readers actually ask, not from a list of popular queries. Conclusions rest on data whose owner and date can be named.

Limits of applicability

What is written here is not individual advice. A reader situation may differ from the one described, and only a specialist who knows the details can check that.

Updating the material

A published piece is revisited when the data it rests on changes. The date of such a review is shown on the page itself.

Editorial policy

Material on this site is prepared and checked by Marcus Thornton.
