At least that’s the buzzy headline the ABA Journal put on this study, in which 200 volunteers rated the “manliness” and confidence, among other qualities, of 60 male lawyers’ opening statement to the Supreme Court. The manliest-sounding lawyers more likely to lose, and the most confident-sounding lawyers were more likely to win. Presumably there was not a lot of overlap between the two.

One of the researchers, Alan Yu, wonders if men tend to compensate for a lack of confidence by using a “manlier” voice at oral argument.
