- everforward 2y agoThat’s the desired effect; getting sleepy is what the study is trying to measure. The problem is when side effects are so severe that people know whether they’ve had a placebo or not, tainting measurements of the actual effect. Eg if a sleeping med caused you to turn purple, the control group knows they haven’t taken it because they aren’t purple, so there’s no placebo effect. Meanwhile the experimental group knows they got the real med because they’re purple, so they have a stronger than normal placebo effect. Because the control group is tainted, you can’t use them to measure and disintermediate the placebo effect of the experimental group.
