There have been double-blind tests performed, but the subjects were quite upset when they learned that apparently it wasn't the wifi signals making them sick, but the blinking lights on the wireless devices.
IE lights disabled, radios fully enabled, on highest power, transmitting data: No symptoms. Simulated status light activity, radios completely disabled and unpowered: symptoms. Lights & radio on : symptoms Lights & radio disabled: no symptoms.
Conclusion: Clearly we need to investigate the status l
The whole reason there is a placebo group is precisely because we know the human brain is susceptible to suggestion. In an experiment like this, there is no reason at all to provide that suggestion.
To expand upon this, in a 'double blind' test, not even those with any contact with the test subjects know whether they're administering the real thing or a placebo. IE those handing out the pills and recording any symptoms don't know. This prevents even more contamination, because the doctor can act differently if he knows which pills he's handing out, and influence the patients that way.
You've described a "blind" study. "Double blind [wikipedia.org]" means that the testers don't know which subject is in which group until after the study.
It's exactly what double blind means. You don't tell the subjects whether they're in the active, placebo, or control groups.
Nope, that's a blind test.
Double-blind means the people handing out the pills also don't know if they're placebo or not. This eliminates any subtle body-language vibes they might be giving out to the people who swallow them.
You had mail, but the super-user read it, and deleted it!

What kind of double blind test is that? It seems deliberately misleading, which would seem to me to be the opposite of a blind test.

Triple blind is when the gov't kills everyone involved in the test.
