Mind-Body-Mind

Here’s a summary of a couple of recent experiments demonstrating deep placebo/nocebo effect. It’s not too surprising that, when told that their DNA test results reveal a particular genetic predisposition, study participants demonstrated attitudes, feelings, and behaviors consistent with that genetic marker, even when the DNA results are fake news. But the participants also underwent physiological changes consistent with the fake genetic news.

This work comes out of the Stanford Mind & Body Lab, which “focuses on how subjective mindsets (e.g., thoughts, beliefs, and expectations) can alter objective reality through behavioral, psychological, and physiological mechanisms.” They’re tracing a causal cascade that runs opposite from but complementary to that of contemporary neuroscience, which explores how brain physiology shapes subjective mindsets. Then there’s this earlier study from Harvard demonstrating that placebo responsiveness might itself be genetic.

These sorts of findings tend to stimulate extravagant inferences.
