Our editorial standard
Every article separates observation from interpretation. We identify what a source says, explain where uncertainty remains and avoid language that turns a general idea into an individual promise.
Readers should be able to understand the limits of a claim, the context of a training example and the questions that deserve professional attention.
Good training writing should make the next question clearer, not make the reader feel pressured to act.
