The Claim

Conditioning-only (C-only) placebo analgesia manipulation produces no significant effects on pain ratings, nociceptive flexion reflex, or autonomic responses

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Challenges

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

A fake pain treatment that only uses learned associations from past experiences doesn't actually change how much pain people feel or how their body automatically reacts to pain.

What the research says

1 study

  1. Study: The Influence of Placebo Analgesia Manipulations on Pain Report, the Nociceptive Flexion Reflex, and Autonomic Responses to Pain.

    The study tested a conditioning-only placebo treatment (where you learn that a treatment works through repeated experience but aren't told it will help) and found it had no effect on pain, spinal reflexes, or body stress responses. This matches exactly what the claim says would happen.
