Ugh, what a messy study! Maybe not 100% useless (though it sounds like it's at least 95% useless without significant further follow-up, but so goes the course of much science, really. "Mixed results, some potentially significant things not tested or controlled for, needs more data and more replication and more analysis" is not inherently bad or anything.) But definitely not worth reporting on as the media apparently has -- which, of course, is nothing new with the media and scientific studies, especially in psych, but ooof.
