"Susann Wagenknecht has written an important book that uses empirical methods for testing and refining philosophical theories about the nature and collaborative creation of scientific knowledge. ...I believe this is the first book that makes a serious attempt to study these philosophical topics with an empirical methodology. The book delivers important insights and is recommended reading for both philosophers and social scientists interested in epistemic collaboration and creation of scientific knowledge."
