I have a friend who, as a psychology researcher at a major university, did a meta-analysis of the reproducibility of psychology research and found much the same as this article. Results were generally not reproducible and there is way too much confirmation bias.

Something else he found was that the tenure track policies for most universities encourage poor study design by rewarding the quantity of research published rather than the quality of the research. That resulted in research departments doing 10 studies with 10 participants rather than 1 study with 100 participants, given a certain amount of funding available.
