Pressure to 'publish or perish' may discourage innovative research, UCLA study suggests
The researchers' conclusions are drawn from a database they assembled of more than 6 million scholarly publications in biomedicine and chemistry

The traditional pressure in academia for faculty to "publish or perish" advances knowledge in established areas. But it also might discourage scientists from asking the innovative questions that are most likely to lead to the biggest breakthroughs, according to a new study spearheaded by a UCLA professor.
Researchers have long faced a natural tension and tradeoff when deciding whether to build on accumulated knowledge in a field or pursue a bold new idea that challenges established thinking. UCLA assistant professor of sociology Jacob Foster and his co-authors describe it as a conflict between "productive tradition" and "risky innovation."

The study found that a remarkably consistent pattern characterizes contemporary research in biomedicine and chemistry: more than 60 percent of the papers had no new connections, meaning that they primarily built on tradition and eschewed innovation.
Drawing on their analysis of scientific rewards, Foster and his colleagues argue that researchers who confine their work to answering established questions are more likely to have the results published, which is a key to career advancement in academia. Conversely, researchers who ask more original questions and seek to forge new links in the web of knowledge are more likely to stumble on the road to publication, which can make them appear unproductive to their colleagues. If published, however, these innovative research projects are more highly rewarded with citations. And scientists who win awards -- especially major ones, like a Nobel Prize -- have more of these innovative moves in their research portfolio.
"Published papers that make a novel connection are rare but more highly rewarded," said Foster, the study's lead author. "So what accounts for scientists' disposition to pursue tradition over innovation? Our evidence points to a simple explanation: Innovative research is a gamble whose payoff, on average, does not justify the risk. It's not a reliable way to accumulate scientific reward."
