They are raising FUD about the research. One of the guys has a PhD in medical psychology and appears to be a right wing nut. There is a nice quote in the article: "It's kind of like the same issues that came up with tobacco denial of health effects or denial of climate change health effects," Frey says. "There's a very small community that have scientific credentials but are moving outside their area of expertise to try to raise doubt after doubt after doubt on issues where they really don't have the strongest competence."
