The ENCODE fiasco is just one of many examples where the scientific literature got it wrong. We need to make sure that our students appreciate the important parts of science; namely, the necessity of repeating experiments and the value of scientific consensus. Our students, and many of my colleagues, are prone to hype and promotion just like every one else but that's exactly what critical thinking is supposed to avoid. And it's exactly what proper science—no matter how you define it—is designed to overcome.
If students and scientists are having trouble with these concepts, imagine how difficult it is for the general public. How are they supposed to know that not every "breakthrough" is a real breakthrough and not every new study is correct?
John Oliver did an excellent job of explaining the problem on a recent (May 8, 2016) episode of Last Week Tonight. Watch it. It's worth 20 minutes of your time. The last bit on "Todd Talks" is classic.
