A researchers' propensity for risky projects is passed down to their doctoral students -- and stays with trainees after they leave the laboratory, according to an analysis of thousands of current and former PhD students and their mentors. From a report: Science involves taking risks, and some of the most impactful discoveries require taking big bets. However, scientists and policymakers have raised concerns that the current academic system's emphasis on short-term outcomes encourages researchers to play it safe. Studies have shown, for example, that risky research is less likely to be funded. Anders Brostrom, an economist studying science policy at the University of Gothenburg in Sweden, and his colleagues decided to examine the role of doctoral education in shaping risk-related behaviour -- an area that Brostrom says has been largely overlooked. "We often focus on thinking about how we can change the funding systems to make it more likely for people to take risks, but that's not the only lever we have," says Chiara Franzoni, an economist at the Polytechnic University of Milan in Italy. This study is "refreshing" because "we've discussed policy interventions a lot, but we haven't discussed training," she adds. [...] The team found that students' risk-taking dispositions matched those of their supervisors. This link was stronger when students and their supervisors communicated frequently, and weaker when students were also mentored by scientists outside their lab.Read more of this story at Slashdot.
