Independent proof outranks every vendor-authored source.
Practitioners consistently placed sources they can verify themselves at the top. Hands-on evaluation and peer references were near-universal, while vendor-authored material sat at the bottom of the trust order.
The implication for go-to-market is direct. Original, practitioner-sourced research and real proof-of-value moments are the credibility currency of this category. Collateral supports a decision that trust has already made possible.
