"Yesterday, I hit a nerve on Twitter. Ok, more than one. But it resulted in a great discussion about open access and brought up some interesting questions. I’d like to take the opportunity to explain in more detail what I meant and did not mean by my tweet. And then I’d like to open up the discussion further. But first, the backstory.
I am writing a systematic review. For those not familiar with the concept, this is not simply summarizing work others have done in a particular area of research. It involves designing searches, implementing filters, and clearly outlining criteria for selecting or excluding articles. The idea is to give a complete overview of the literature and be able to quantify, for example, what percentage of studies in the research area used a certain technique, or arrived at a common conclusion."
