In science, citations are used to give credit to sources that are relevant to the topic that is being discussed where the citation appears. They are a key vehicle through which we establish a cumulative knowledge tradition – we use them to acknowledge material that informs our arguments. But citations are much more than that. They have become a key metric of academic success in their own right, providing a quantifiable basis to measure a scholar's impact, reputation, and fame. And as any metrics-based systems, also the citation system can be gamed, and is being gamed. Time to unpack the role that citations play and discuss which citations are legit – and which may just be a bit flunky. As usual, the references to readings we mention are listed on http://www.janrecker.com/this-is-research-podcast/.
