The rhetorical move of accusing someone of believing in or promoting pseudoscience as a way of dismissing their claims without engagement. The accusation functions as social and intellectual exclusion—positioning the target as gullible, irrational, or unsophisticated. The fallacy lies in using the accusation itself as the argument, rather than addressing the actual evidence or reasoning. It's ad hominem by methodological association: you don't have to refute someone if you can successfully frame them as a "pseudoscience believer."
"I mentioned that I've found meditation and energy work helpful for my anxiety. Response: 'That's just pseudoscience—you're believing in woo.' That's Pseudoscience Accusation Fallacy—using the label to dismiss, not engaging my experience or the evidence. Whether it's 'pseudoscience' or not, my anxiety improved. The label doesn't negate the outcome; it just avoids engaging it."
