Most people have little understanding of actual scientific processes. The media conglomerates like Sinclair love to play on this. They'll have segments like "a glass of red wine a day prevents heart disease" only to later have a segment saying "a glass of red wine a day contributes to heart disease" because of two different competing studies. These studies probably had different sample size, quality, and of course tons of unknown variables, but they drive the traffic either way and the media doesn't care.
