The article does a great job of it, too:

"Caveat: The study was relatively small and involved children who were still learning how to read."

Your only take-away isn't supposed to be some editor's choice for the title.

This is why I don't like the "tl;dr" meme. If people would take more time to absorb the information related to topics we care about, there wouldn't be this desire to have a random person on the net distill that knowledge into something you can consume in 20 seconds or less. It's like getting all of your political opinions from Comedy Central. You're willingly getting your information through yet-another filter, but this filter is presented as unbiased.

Edit: parent comment ninja'd what I was responding to, now this looks super off topic.
