It's just another study by people with an agenda.
Yes, but this time they have CONCLUSIONS! Which is more newsworthy than an unbiased study by honest researchers who caution people not to overreact to their results. It is always this way, which is why even after that study linking vaccines to autism has been completely demolished, a depressing amount of people still run around thinking that autism is caused by vaccines. That study was poorly done, and the results were announced to the world as final proof rather than something that would merit at most one or two repeats of the experiments before it was taken seriously.
If you want to get a lot of attention and don't care that all of the serious professionals in your field will immediately see that you are a quack and will eventually prove you wrong, then make a quick study and shout your results as the word of God for all the public to hear.
""We can now say with utmost confidence that regardless of research method -- that is experimental, correlational, or longitudinal -- and regardless of the cultures tested in this study [East and West], you get the same effects,"
Yes, you can say that, Mr. Anderson. You should also point out IN THAT SAME FUCKING BREATH that regardless of research method, YOU COULD STILL EASILY BE WRONG. As you're promoting this as infallible truth, based on research you didn't even do, I'd say that increases the chances that you're wrong, because you're a complete moron.
I'm actually a bit surprised he actually says policy needs to be changed, rather than "Elect me to be supreme overlord and I'll have this whole violence thing sorted out in a month." I mean, if you're going to boldly overstate your results, then by God, overstate your results, don't pansy out at the end and suggest someone else be empowered to deal with it.
