Title:
The Universal Link Between a Mentor’s Tacit Knowledge and a Protégé’s Scientific Success
Abstract:
Modern science is arguably in the epoch of collaboration. Mentorship is often a scientist's first, most formative, longest lasting, and in some cases compulsory collaborative relationship, yet a dearth of large scale quantitative studies of scientific mentorship leave central questions unanswered. We collected 100 years of intricate data on the publication records, genealogical networks, and social networks of 50,000 mentors and protégés in diverse fields worldwide to test if mentorship adds value to protégés’ existing talents and how it is imparted from mentors to protégés. Using a quasi-experimental design, we report three novel findings. First, mentorship strongly predicts protégé success on a wide range of scientific performance outcomes. Worldwide and universally across diverse disciplines and time, protégés of mentors who have scientific tacit knowledge about how to conduct and publish acclaimed research are two and a half times likelier to be science prizewinners, four times likelier to be elected to the National Academy of Sciences, and two times likelier to write high impact articles than control group protégés. Second, the positive impact of mentorship increases with the talent of the protégé at an increasing rate. Third, we demonstrate that mentorship neglect can undercut the imparting of critical tacit knowledge from mentors to protégés, which in turn is associated with a delay in the time even the most highly talented protégés take to make their leading scientific discoveries.

TALK TITLE:
Human and Machine Perception of Voice Similarity
ABSTRACT:
Modern voice cloning systems generate synthetic speech that listeners frequently cannot identify as being synthetic. But a voice can sound natural without sounding like the intended person, and what determines whether a clone is heard as a particular person is an open question. Here we report a large-scale preregistered experiment in which we collected 92,239 responses from 175 participants on their perception of pairs of real recordings, voice clones, and continuously morphed voices drawn from 100 contemporary celebrities across 20 speaker groups. We find that voice clones do not reliably preserve perceived speaker identity, reducing same-speaker judgments by 12.7 percentage points even though the clones are produced by a state-of-the-art text-to-speech model, while leaving different-speaker judgments unchanged. Using continuously morphed stimuli, we find that speakers vary substantially in how much variation their perceived identity tolerates, and that this variation is not predicted by speaker demographics. Speaker embeddings account for 58.9\% (95\% CI = [55.7, 61.9]) of variance in identity judgments, which is more than acoustic features, social attributes, and clone status combined. Once all these observed features are accounted for, clone status adds no additional predictive power. These results shows that the perceptual impact of voice cloning is positional rather than categorical: we can model how listeners judge a voice by how close it falls to the perceptual boundary that defines each speaker's recognizable voice, applying the same criterion to real and synthetic speech alike.
DATA SCIENCE NIGHTS are monthly meetings featuring presentations and discussions about data-driven science and complex systems, organized by Northwestern University graduate students and scholars. Students and researchers of all levels are welcome! For more information: http://bit.ly/nico-dsn
