One more thing I guarantee I'll be saying "told you so" in 5-10 years when something on it leaks, just like the NSA spying before Snowden, and many other things.
Mass hysteria is real (muh Russians via shareblue, for example) but I really don't think this is one of those cases.
I love the careful logically falacious setup in the article though, very masterful. When you finally get to the meat of the claim, by a man who is selling books on hysteria (nail-hammer problem) he already discredits himself via the statement: “It is physically impossible to have brain damage caused by an acoustical device." Well that's just not correct. What else is he obviously not correct on? Has he seen the evidence from StateDep and CIA? Nope, so he's making claims without seeing all the evidence. Then immediately the article transitions from their baseless claim on this particular incident to saying "oh but even if it's hysteria it can still have real effects ala placebo". See how subtlely they pass over the problems of their own claim and manipulate the reader? And then to see the author is also the author of a "everything is a syndrome" book is just icing on the cake.
Especially funny they mention the Taos hum... if only ya'll had any idea what that really was... HN isn't ready for such a truth bomb though. (I'll give you a hint. DUMBs)
