Claim audits

Was Warren Buffett right? Nothing here carries a rule JMM can score.

Each audit records the exact statement, the source with a locator and retrieval date, a verdict class, and the timeline that settled it. Attribution is not a truth score: a claim without a measurable rule stays under review, per the publication standard.

Under review

The market is a voting machine in the short run and a weighing machine in the long run

No measurable rule is attached: no timeframe, threshold, or settlement source, so JMM assigns no truth verdict. The long-run half of the claim has substantial supporting evidence, and the short-run half is routinely demonstrated by market behavior.

How a verdict is earned

Gold, red, or neutral, with a reason

Supported means the measurable claim held against the evidence on the record. Contradicted means it failed its own test. Under review means no scoring rule exists yet, and JMM says so instead of forcing a score. Every verdict page lists the evidence items that produced the call, and every audit carries a reply window.
