My folks have come to the conclusion that since the media can twist any data or studies however they like, then there's no way to know what the science actually proves. So they believe nothing. Unless it's something that agrees with what they already believed.
Unless! Unless it is something that directly affects them! My mother has gone all in on the ADHD and autism studies in the past decade or so, since it turns out these are common in herself, her children, and grandchildren. Yet she can't understand or accept someone not being cishet.
