Neuroscientific Defaultism

A cognitive and epistemic bias where neuroscience is assumed to be the fundamental or only legitimate framework for explaining mind, behavior, and human experience. It treats all psychological, social, or philosophical phenomena as ultimately reducible to brain activity, and dismisses non‑neuroscientific accounts as merely “folk psychology” or “unscientific.” The defaultism lies in never questioning whether neuroscience is appropriate for every question—it simply is the default. This bias often manifests in claims like “your depression is just a chemical imbalance” or “love is just oxytocin,” ignoring the rich layers of meaning, context, and lived experience that neuroscience alone cannot capture.

Example: “He explained every human decision as a product of dopamine and serotonin—neuroscientific defaultism, reducing friendship, art, and politics to neurotransmitter levels without ever asking if that reduction was useful.”

Neuroscientistic Defaultism

A more ideologically charged version of neuroscientific defaultism, where scientism (the belief that science is the only source of genuine knowledge) is applied specifically to neuroscience. It holds that any claim about mind, behavior, or society must be validated by neuroscientific methods to be considered real or meaningful. Insights from psychology, sociology, or the humanities are dismissed as “soft” or “anecdotal” unless they can be “translated” into brain scans. Neuroscientistic defaultism often appears in debates about free will, consciousness, or morality, where brain imaging is treated as the final arbiter of truth.

Example: “He demanded an fMRI study to prove that people had moral intuitions—neuroscientistic defaultism, refusing to accept philosophical or behavioral evidence unless it came with a brain picture.”
