Okay – I was going to post that SAT thing on here also, but my roommate (who sent it to me initially) pointed out some serious flaws:
“It is funny that it doesn’t look like the scale goes up to 1600.And also how many Christian bands it samples. And how it may be more of a socio-economic reflection than anything. Also, that it probably isn’t ‘actually’ scientific.”
I would argue that this is a flagrant abuse of statistics. Correlation does not imply causation!!!!
Note: the comment I just made was actually a response to the sister infographic: “BandsThatMakeYouDumb.” Same concept, though.
Yeah I definitely agree. On a related note: http://xkcd.com/552/
I was definitely about to post that!
