Ted Kaptchuk

Overview

Ted Kaptchuk is the placebo researcher whose lab’s asthma study supplies the episode’s clearest distinction between symptom experience and measured physiological function.

Current Profile

Within How Placebo Effects Work to Change Our Biology & Psychology, Kaptchuk’s work anchors Symptom–Function Dissociation. Participants receiving placebo reported less breathing discomfort without improved breathing patterns, whereas active asthma medication improved both experience and function. The example makes subjective relief clinically meaningful without treating it as proof that airway physiology has normalized.

Key Characteristics

• Conducts clinical research on placebo responses.
• Is associated in the source with an asthma experiment comparing no treatment, placebo, and active medication.
• Helps separate perceived symptom burden from objective functional change.
• Provides a boundary against using symptom relief as a substitute for effective disease treatment.

Evidence

Asthma placebo comparison

• How Placebo Effects Work to Change Our Biology & Psychology attributes the asthma study to Kaptchuk’s lab and reports divergent subjective and physiological outcomes.

Clinical interpretation

• How Placebo Effects Work to Change Our Biology & Psychology uses the study to argue that placebo can alter discomfort even when the underlying breathing measure does not improve.

Qualifications

The episode note does not supply the full protocol, outcome measures, effect sizes, or broader asthma literature. Placebo-related comfort is not evidence that rescue or controller medication can safely be withdrawn.

What Changed

• Created a source-bounded profile centered on the asthma symptom-function distinction.

Relationships

• Symptom–Function Dissociation - central clinical distinction grounded by Kaptchuk’s asthma study.
• Placebo, Nocebo, and Expectation Effects - broader expectation-effect research domain.
• Fabrizio Benedetti - fellow placebo researcher used elsewhere in the episode for neural and Parkinson’s examples.
