A deceptive practice where individuals invoke "evidence-based" as a rhetorical shield to legitimize their positions while ignoring, misrepresenting, or selectively applying evidence. The evidence-based charlatan uses the language of empiricism to claim authority, but their engagement with evidence is superficial—citing studies that support their view while ignoring contradictory findings, demanding impossible standards of evidence from opponents, and treating their own preferred evidence as self-evidently correct. They weaponize "evidence-based" to shut down debate, positioning themselves as the rational party and all alternatives as unscientific. The charlatanism lies in using the idea of evidence to avoid the actual work of evidence evaluation, turning a valuable methodological commitment into a performative identity.
Example: "He demanded randomized controlled trials for his opponents' claims while citing blog posts as evidence for his own. Evidence-Based Charlatanism: using the language of rigor to avoid the practice of it."
