Poor peer review – and its consequences

See below for citations used The diagram above displays links between the journal, editors and reviewers in the case of the paper Malin & Till (2015). I discussed these links before in Poor peer-review – a case study  but thought a diagram merited … Continue reading

This has been a common theme here as I have campaigned against cherry-picking research papers, relying on confirmation bias and putting blind faith in peer-review as a guarantee of research quality. In short I have pleaded for readers to approach published research critically and intelligently. The article The 10 stuff-ups we all make when interpreting research from … … Continue reading
