Not long ago, Science Careers posted a widget—you can find it at—that lets early-career scientists calculate the probability that they'll someday become principal investigators, on the basis of a few standard publication metrics. The widget builds on work published 2 June in Current Biology ( in which the study's three authors—all early-career computational biologists—used PubMed data to study the influence of some 200 factors on academic scientists' career trajectories. Built by John Bohannon, a contributing writer for Science Careers, and David van Dijk of the Weizmann Institute of Science in Israel (the lead author of the Current Biology study), our widget employed a simplified model based on the same data set.
