We take the loudest claims circulating about AI coding and check them against published evidence. Three verdicts, every week. Sample below — all three are real, sourced cases.
CONFIRMED
"AI-generated code ships more defects than human code."
A December 2025 analysis of 470 open-source pull requests found AI co-authored code contained roughly 1.7× more major issues, 75% more misconfigurations, and 2.74× more security vulnerabilities than human-written code.1

UNPROVEN
"Only 0.02% of vibe-coded apps succeed."
This figure circulates widely in 2026 commentary. No methodology has been published for it, which makes it impossible to verify.2 A number without a method is a slogan, not a statistic — even when it argues our side.

PATTERN
"This free tutorial is neutral advice."
Multiple 2026 "beginner vibe coding" videos carry affiliate tracking links (pxf.io / Impact network) and "$499 masterclass — free" funnels in their descriptions.3 The tool recommendation is paid placement. The description exposes it; the video never says it.
