The blanket assertion that any claim labeled "pseudoscience" is automatically false, worthless, or beyond consideration. The fallacy lies in treating a methodological judgment (this doesn't meet scientific standards) as a truth judgment (this is false). But pseudoscience can contain true claims—astrology includes accurate psychological insights; homeopathy might include placebo effects that are real; ancient traditions often have empirical knowledge embedded in non-scientific frameworks. The label "pseudoscience" describes relationship to scientific method, not truth value. Using it as a synonym for "false" is category error dressed as critique.
Pseudoscience Equals False Fallacy "They dismissed acupuncture entirely with 'it's pseudoscience, so it's false.' That's Pseudoscience Equals False Fallacy. But acupuncture might work for some conditions, even if the traditional explanation isn't scientific. 'Pseudoscience' describes the framework, not the outcome. Truth doesn't require scientific packaging; dismissing everything in the package because the package isn't scientific is throwing out babies with bathwater."

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."

The blanket assertion that any claim associated with parascience—fields like parapsychology, telepathy, astral projection, or spiritual experience—is automatically false. The fallacy lies in treating "outside mainstream science" as synonymous with "false." But parascience includes phenomena that may be real but not yet scientifically explained, experiences that are real as experiences even if their interpretation is debated, and claims that may eventually be incorporated into expanded scientific frameworks. The label "parascience" describes relationship to current scientific consensus, not truth value. Assuming it equals false is assuming current science is complete—which is itself unscientific.
Parascience Equals False Fallacy "I shared my experience of what felt like communication with a deceased family member. Response: 'That's parascience, so it's not real.' That's Parascience Equals False Fallacy. The experience was real to me; what it means is open to interpretation. Dismissing it because it doesn't fit current science is confusing the map for the territory. Science changes; experiences don't disappear just because they're not yet explained."

The rhetorical move of accusing someone of being into "parascience" as a way of dismissing their experiences, beliefs, or claims without engagement. The accusation positions the target as credulous, unscientific, or mentally unstable. The fallacy lies in using the accusation itself as the argument—as if labeling something "parascience" does the work of refutation. It's a conversation-ender that allows the accuser to feel superior without having to engage the actual phenomena or experiences.
"I tried to explain my meditation experiences and the sense of connection I feel. Response: 'Oh, you're into all that parascience stuff.' That's Parascience Accusation Fallacy—using the label to dismiss, not engaging what I actually said. My experiences are real to me; calling them 'parascience' doesn't make them disappear. It just shows you're not interested in understanding."

Where-Is-Your-God Fallacy

A dismissive rhetorical move, often used in debates about religion or spirituality, where someone demands physical proof of the divine—"Where is your God? Show me!"—as if the absence of physical evidence proves non-existence. The fallacy lies in demanding a kind of evidence that the claim, by its nature, doesn't offer. Spiritual experiences aren't physical objects; divine reality, if it exists, may not be empirically accessible in the way rocks and trees are. The demand for physical proof of non-physical claims is category error dressed as skepticism.
"I tried to explain my spiritual experiences. Response: 'Where is your God? Show me a photo!' That's Where-Is-Your-God Fallacy—demanding physical evidence for what may not be physical. Spiritual claims aren't scientific hypotheses; they're about meaning, experience, and transcendence. Demanding empirical proof is like demanding to hear a painting. Wrong tool for the domain."

You-Are-Brainwashed Fallacy

The rhetorical move of accusing someone of being "brainwashed" as a way of dismissing their beliefs, commitments, or arguments without engagement. The accusation positions the target as incapable of independent thought, their views as mere programming. The fallacy lies in using the accusation as a refutation—as if demonstrating that someone is brainwashed (which you haven't actually demonstrated) proves their views are false. But even brainwashed people can hold true beliefs; the source doesn't determine truth. The accusation functions to avoid engagement by pathologizing the believer.
"I explained why I find meaning in my religious community. Response: 'You've just been brainwashed since childhood.' That's You-Are-Brainwashed Fallacy—dismissing my actual reasons by attacking my capacity for reason. Maybe I have thought critically; maybe my commitments are examined. The accusation lets you feel superior without having to engage a single thing I said."

You-Are-Delusional Fallacy

The rhetorical move of accusing someone of being "delusional" as a way of dismissing their perceptions, experiences, or beliefs without engagement. The accusation positions the target as mentally unstable, their views as symptoms rather than claims. The fallacy lies in using the psychiatric label as a refutation—as if naming a pathology does the work of argument. But even people with delusions can have valid perceptions; more importantly, using "delusional" as a casual dismissal trivializes real mental health issues while avoiding intellectual engagement.
"I shared my near-death experience and what I learned from it. Response: 'You're delusional—that's not real.' That's You-Are-Delusional Fallacy—using a psychiatric label to dismiss an experience without engagement. Maybe it was real; maybe it was brain chemistry; maybe it was something else. But calling me delusional doesn't address any of that—it just ends the conversation while making you feel clinical."
