When someone approached us, we first tried to learn about their prior knowledge on the topic of preprints. So, we asked something like, "Have you heard of preprints before?" or "Have you ever posted a preprint?" To our surprise, a staggering number of people did not know what preprints were. Some seemed to have heard of bioRxiv or arXiv, but did not really know about preprints, why they should care, or how they could benefit their careers. A couple of people smiled at us, saying that they came from the physics or computer science worlds, where "of course we have heard of preprints!" In those fields, preprints have been around for 25 years; sadly, life science fields are slow to catch up to preprints, but the number of preprint submissions has been going up quickly in the past few years (Figure 2).
