Although it's probably futile to do so, since you have beeen consistently ignoring all contrary evidence to your claims (e.g. all the people who have pointed out that many treatment studies include objective observational measures and manipulation checks), I'll point out here that there is a long history of demonstrated placebo effects on non-self-report measures, including: heart rhythm blood pressure sensorimotor impairment gastric acid secretion in ulcer patients ACC, prefrontal, orbitofrontal, and amygdala activation dopamine levels immune system functioning asthma symptoms bronchitis symptoms respiratory depression Anyone with a basic understanding of classical conditioning can see how placebos could have such effects. --- You are currently subscribed to tips as: [email protected].
