Also, publish-or-perish is linked to scientific misconduct or at least questionable ethics.  It has also been argued that the quality of scientific work has suffered due to publication pressures. Physicist Peter Higgs , namesake of the Higgs boson , was quoted in 2013 as saying that academic expectations since the 1990s would likely have prevented him from both making his groundbreaking research contributions and attaining tenure . "It's difficult to imagine how I would ever have enough peace and quiet in the present sort of climate to do what I did in 1964 ," he said. "Today I wouldn't get an academic job. It's as simple as that. I don't think I would be regarded as productive enough."
