The Dana Foundation has a reputation for translating neuroscience for the lay public without hype or distortion. This article in Dana’s publication, Cerebrum, warns that scientists themselves need to do a better job of peer review.
In my opinion, it is likely that the field of neuroscience is detecting only the tip of the fraud iceberg. Even though most scientists conduct their research impeccably, there is more misconduct than journal editors and the scientific community detect. This is mainly because cheating can be difficult to uncover.
