I can't really say much, as I'm unable to read the paper without paying for it, but the article from HP just seems to be another puff-piece. It doesn't detail any of the studies reviewed, their methodologies, or their actual findings beyond 'these studies say religious people are dumb'. I'd like to know what kind of tests were done to get these results. Was it just a question of what's your IQ and do you believe in God? Was their a scale for religiosity, or was everyone blanketed as religious? Was their an intelligence spectrum test given during any of the studies to test for high intelligence in non-IQ areas? Did the professor who performed the study look at counter-examples and dissenting studies? We don't know. So, to me, its not actually saying anything, and as an EE major it's stuff like this that really makes me mad because it doesn't actually represent anything scientific to the reader, but purports a conclusion, while their is only a correlation - however slight. The journalistic community only lives to entertain the reader and to make a buck, not to educate them.
