||This study analyzes the editorials in Science and Nature published between 2000 and
2012 about careers in science. Of the total body of documents, 8.8% dealt with science
careers. The editorials were manually classified by topics and then mapped using the
VOSviewer. This revealed six easily distinguishable clusters: career conditions in
science, the attractiveness of science as a career, merit-based career policies, the effect of
research funding on careers, specific groups underrepresented in science, and mobility of
scientists. The paper summarizes the main thrust of the arguments in these editorials.
There is strong agreement about the problems in scientific careers, but less consensus on
the solutions to these problems. The paper also explores whether mapping on the basis of
automatically identified terms could have provided adequate results, but concludes that
manual classification is needed.
