The idea in practice

A primary source is useful because it directly supports a fact, not because the label makes every statement on the page correct. Match the source's date, scope and subject to the question being answered.

Try the distinction on a real task

This is an illustrative request, not a customer result or a promise that every connected service supports every step.

Use the organizer's current page for the deadline, and keep commentary in a separate section.

How to apply it

  • Identify the decisive facts
  • Find the sources responsible for those facts
  • Read the exact supporting passages

What to check

Check whether a citation establishes the claim's year, market and conditions.

A mistake to avoid

Do not use a prestigious but unrelated source to give an unsupported sentence an appearance of authority.

Using Bris for this work

Bris can browse public sources and bring findings back to your chat. Specify what would make an answer useful: current evidence, comparable options, source links and an honest account of gaps. Access restrictions and changing websites can limit what is verified.
