The "2× engagement / conversion" interactive-content stat is widely (mis)attributed to "Content Marketing Institute" — no original CMI dataset producing it exists

Summary

Claim: The popular "interactive content gets 2× engagement / conversion" stat is widely (mis)attributed to Content Marketing Institute (CMI). No original CMI dataset producing it appears to exist; the citation chain terminates at Demand Metric 2014 Content & the Buyer's Journey Benchmark Study — vendor-sponsored online opinion survey of 185 marketers; the "2× engagement" headline rounds 70%/36% — a vendor-sponsored opinion survey.

Source: Trace of citation chains across vendor blogs; original Demand Metric report (Demand Metric, 2014).

Confidence: Verified — the misattribution is reproducible by checking the cited sources.

Why this matters for Candid: This is a recurring pattern across the marketing-stat ecosystem (MIT / InsideSales.com Lead Response Management Study 2007 (Oldroyd) — odds of contact drop ~100× from 5min to 30min; commonly misattributed to Harvard is mis-attributed to Harvard; the McKinsey 83% B2B-transparency stat is laundered through vendors). It supports R5 — Disregard vendor-sourced "interactive content converts better" statistics in client conversations and informs Candid's broader citation discipline (see existing topic citation-practices).
