The Internet phenomenon of watching cat videos, from Lil Bub to Grumpy Cat, does more than simply entertain; it boosts viewers' energy and positive emotions and decreases negative feelings, according to a new study by an Indiana University Media School researcher.
According to the press release, it was done by a school of media studies via social media based survey. I wouldn’t call this rigorous, or even really preliminary.
This is the kind of research homeopaths trot out in attempts to validate the claims on the side of the bottle of water. Not really science, so much as a straw poll.
