"What do we want? Evidence-based science! When do we want it? After peer review!" We have come to think of peer review as the stamp of quality that separates real results from mere conjecture, but a look under the hood reveals that the participants inside of peer review are far from objective. This book reclaims subjectivity and affirms a social mode of objectivity, which prevents peer review from overpromising and underdelivering in its vital role in knowledge production.
