As for the other theories I mentioned, very often the people denying science or supporting pseudo-scientific ideas will flat-out tell you why they're doing it. If not, you might have to dig a little deeper. You know something is wrong when someone contradicts a massive body of evidence discovered by other scientists. Even moreso when the person contradicting everyone else has a political motive.
In reality, the studies that have been done about these things invariably turn up either "false" or "invalid procedure." It's always one or the other. I'm sure if this one were any different, no one would be complaining. And if there were any reputability to this study, I too would be very excited.
It's absurd because it goes against common sense first, and against all other scientific discoveries second. As the article phrases it, this violates almost all scientific laws discovered before. If you want to overthrow all scientific research of the past 400 years, you'd better have a little bit more than a few studies involving human psychology that were obviously tailored to obtain a particular result.
