Frequently asked questions

What is Red Cardinal Research?

An independent research publication studying the systems shaping the next decade — markets, housing, artificial intelligence, defense, healthcare, frontier technology and human behaviour. We explain why things happen and how systems connect. Primary sources first, dated judgments, and public corrections when we are wrong.

What is available for free?

All published articles. The newsletter. Every calculator. The concept layer — definitions, why each idea matters, common mistakes, and where each concept breaks down. Company snapshots for all 100 companies. And three full company dossiers of your choosing once you create a free account.

What is included with premium?

Unlimited company dossiers, Connected Systems (the full concept map, dossier routing and research paths), the premium archive, and premium reports.

How do the three free dossiers work?

Create a free account, browse the RC 100, and open any three dossiers in full. You choose which — nothing is pre-selected. No card is required.

Do the selected dossiers expire?

No. Once opened, a dossier stays available on your account permanently. Note that an unlock is also permanent in the other direction: you cannot currently swap one for a different company, so choose companies you genuinely follow.

How do I sign in?

There is no password. Enter your email on the sign-in page and we email a one-time link that expires in an hour.

How do I update my email preferences?

Sign in and open Settings. Each email type can be switched on or off separately. Every email also carries an unsubscribe link.

How do I manage or cancel my membership?

Sign in, open your account, and choose Manage billing. That opens Stripe's portal, where you can change plan, update payment details, or cancel in one step.

What happens after cancellation?

You keep full access until the end of the period you have already paid for — nothing is cut off mid-period. After that your account reverts to the free tier. You keep your account, your saved research, and any dossiers you unlocked on the free tier. See the cancellation policy.

How do I report a factual error?

Use the contact form and choose Report an error. Tell us the article and the specific claim. Material corrections are published, not quietly edited — see the corrections policy.

How are sources verified?

Primary sources first. Every load-bearing claim needs a primary source and an independent check. And a striking, quotable number that appears in only one secondary source does not ship — a rule that has already caught several widely-repeated figures that turned out to be wrong. See editorial standards.
