I'm getting quite depressed by the increase prevelence of these types of dismissive comments on studies. You see this exact argument posted especially on Reddit.
The second increasingly common popular comment is "Yeah but is it causal? and not correlation?", including popular follow ups such as did they correct for socio economic status? (Which in the vast majority of studies, they always do)
I'm curious to know if the posters of these comments have been to univsersity / college? Have they taken any classes on the basics of scientific method? I remember my bachelors had a course on it, at least.
It's great that more people are interested in science, but it's not great that people dismiss entire studies because they do not understand how science works.
