In research, a scientific approach requires the use of control groups to determine the significance of observations in (clinical) trials. Using such controls to exclude placebo effects and other artifacts is often referred to as a 'blind trial'. Scientific research involving humans is extremely challenging to conduct because of the difficulty in finding appropriate control groups. This is one of the reasons animal experiments (for instance involving inbred strains of mice) are so common.
Here, Randall describes an extremely awkward case of an attempt to do a clinical trial, where a sugar pill is used as a placebo for ‘having sex’.
The title text defines the least of all problems with this approach, hinting at the association of being blindfolded (taking “blind” of the blind trial literally) and S&M types of sexual activity.

- Megan: We've designed a double-blind trial to test the effect of sexual activity on cardiovascular health.
- Both groups will think they're having lots of sex, but one group will be actually getting sugar pills.
- The limitations of blind trials

- I think the item Megan is pointing at should not be referred to as "chart", but as "charts", since a chart is "a sheet of information in the form of a table, graph, or diagram", while there is clearly both a table and a diagram, therefore two "charts".17jiangz1 (talk) 12:45, 19 December 2014 (UTC)
I wonder though, if it makes sense to account for Placebo Effect when you're mesuring something that does not involve subjective perception. In the example case, one can measure, say, heart rate for the group that practices sex and the monastic control group and have valid results. Of course, you lose the option of passing a survey with questions like "Have you lately felt tired?" or the like. 173.245.49.106 09:33, 19 December 2014 (UTC)
- Of course it does make sense, placebo effect can be observed on test for disease such as cancer. The idea is that thinking you are taking a cure might, will trigger physiological change. It is quitte likely, that the testing of pills for the heart would induce some placebo effect. What you might be refering too is some kind of perseptive bias, which could be observed in psychological test. 108.162.229.100 11:51, 19 December 2014 (UTC)
Hmmmm ... maybe you could make the control group think they have sex with hallucinogens ... but somehow I don't think it would make useful control group, not speaking about most hallucinogens being illegal. Alternatively, you can get both groups drunk and - ... ok, this doesn't sound like good idea either. -- Hkmaly (talk) 12:44, 19 December 2014 (UTC)
- I was thinking maybe hypnotherapy... --Pudder (talk) 12:48, 19 December 2014 (UTC)
- the only legitimate thing I could think of is to get the control group to use various forms of cardiovascular exercise to get a few measurable statistics (like heart rate, perspiration, respiration, blood pressure, etc) to be roughly equivalent to those experienced by the experimental group, then the experiment would be to show MOSTLY whatever else sex does (hormones, psychological stimulation, etc), if cancer susceptibility was shown to be lower in the experimental group, it MIGHT have some validity... it would be a fairly complex set of requirements to design and especially hard to control for things like sexual preference(s), but I could imagine a well-designed study being able to show a few things -- Brettpeirce (talk) 14:42, 19 December 2014 (UTC)
When I was diagnosed with accute hypochondria and then suffered a number of psychosomatic injuries, those sugar pills actually saved my life! 141.101.98.245 12:55, 19 December 2014 (UTC)
So, does a triple blind trial mean a threesome? Nialpxe (talk) 16:27, 19 December 2014 (UTC)
Just my luck - I'm in the second group! --RenniePet (talk) 03:18, 20 December 2014 (UTC)
