Yet, whole books and theories are written in pop science because of the one poorly done study. After a study is replicated, it has to be manipulated to see if other things could have caused the effect. Scientists are like detectives solving a mystery, and are always looking to see what could have caused the effect besides what was being tested, and design another study to rule out that variable. So that's why that laymen often think that science is rapidly changing, but it's not, true science moves slowly, as it should.

Yup agreed!!!
