Last week the two scientists Dan L. Longo and Jeffrey M. Drazen, both from medicine, published an editorial, which was also picked up by some news outlets. In this they talk about an emerging class of scientists, who are not anymore involved in the basic data collection, but reinterpret the results of original studies by their own methodologies and by combining several studies into a new dataset. They state that some scientists name this kind of researchers “research parasites” and claim that they are a problem for science overall. The authors prefer a system, where the scientists work directly together and publish their studies as coauthors.
For a few years now, Data Science is a hot topic. Under the theme ‘Big Data’, it got popular and when you believe some media it will solve nearly all problems in the world. But what does it mean to be a data scientist? Is it a jack of all trades or just someone, who know no field really well? As I would myself describe as a data scientist, I would like to write a little bit about how I see this field.
