Low productivity, Higgs believes, would sink his chances for an academic post in today's job market. In the 49 years since he wrote the papers laying out what physicists now call the Higgs model, he has "published fewer than 10 papers," The Guardian notes.
Fortunately for his career, at the time Higgs did his groundbreaking work he had a faculty post at the University of Edinburgh, where he is now a professor emeritus. His scanty publication record made him "an embarrassment to the department when they did research assessment exercises," he says, as quoted in The Guardian. Only a 1980 nomination for the Nobel Prize kept him from being let go, he told the paper.
We need to keep in mind that times have changed. Things that used to work, or things that one can get away with a couple of decades ago, may no longer work now. I cringe every time I hear advices being given to people by using the examples of Einstein and Galileo and Dyson, etc. as indicating that something can be done that way. This totally ignored the reality of today and how things no longer work the way they did back then.
