Document Summary
Psyc 301 topic 2: crisis in neuroscience: allure of neuroscience makes research seem more compelling when adding a brain image, bias to believe natural/hard sciences more credible, findings with irrelevant neuroscience information judged as higher quality. Once you see something, it"s so hard to be objective and review findings normally: one of the most qrped areas of research. Inflated es from small ns -> publication bias probably leads to even lower power: considered unethical to run low powered studies. Inefficient only 1/3 studies are true positives, so it"s also not informative: wasteful of resources, time, money. In 2008 only 74% of fmri articles used correction for multiple comparison: often apply corrections to some comparisons but not others, point to show how failure to correct for multiple testing can yield spurious results. **main criticism with neuroscience research is people act like they can skip validation process of results, everyone assumes that because it"s neuroscience, it"s always accurate**
