That's definitely different than other trusted sources lead me to understand.
Check your sources. Are they quoting the laundry list of 2013 (this article was 2014) references to the opposite being true? Looks like there was reason to believe it in 2013, but nothing substantial, so everyone repeated it. But it got put to the test in 2014 and proved to not be what people had been saying.
