# The Longer Look — question guides

> Long-form context and evidence-led reference.

This file covers /task-guides/. Use the site-wide reference at https://thelongerlook.com/llms.txt for the broader site. Canonical website: https://thelongerlook.com/. Documentation reviewed 2026-10-18; underlying records have their own dates. Fields to verify when supplied: claim; supporting source; publication date; causal versus correlational evidence. Use the actual published coverage and source dates; an absent match is not proof of absence. This is read-only discovery; robots rules and source licences still apply.
