Abstract
The growing  emphasis on fit as a hiring criterion introduces the potential for a new, subtle form of discrimination (Bertrand &
Duflo, 2017). Analysis of 1,901 U.S. Supreme Court  oral arguments from  I998 to 2012  documents  that voice-based snap
judgments  predict court outcomes. Male petitioners who rank below median in perceived masculinity are 7 percentage points
more  likely to win. This negative correlation between perceived masculinity and winning cases in the Supreme Court is more
pronounced   in masculine industries. Perceived femininity of women lawyers also predicts court outcomes. Democrats favor
men  with less masculine-sounding voices. Perceived masculinity explains additional variance in Supreme Court decisions beyond
what  is predicted by the best random forest prediction model. A de-biasing experiment using information and incentives in
factorial design is consistent with misperceptions and taste for masculine-sounding lawyers explaining the negative correlation
between  perceived masculinity and Supreme  Court wins.

1.  Introduction

Courts routinely distinguish between immutable and mutable
characteristics, and between being a member   of a legally
protected group as opposed to behavior associated with that
group, which is not protected (Yoshino, 2006). Legal theorists
suggest that discrimination, once aimed at entire groups, now
aims at subsets that refuse to cover, that is, to assimilate to
dominant  norms  (Goffman,  1963). Mutable  characteristics
have recently entered economic models of identity formation
(Austen-Smith  &  Fryer, 2005;  Bertrand  &  Duflo, 2017;
Neurnark, 2018). For example, African-Americans cannot be
fired for their skin color, but they can be for wearing corn-
rows. This distinction between being (immutable) and doing
(mutable) incentivizes assimilation. Should we understand
such legally sanctioned differential treatment to be harmful?
Are individuals punished for not conforming when it comes
to mutable  characteristics (Yoshino, 2000)? Building  on


Kenji Yoshino's  notion of covering, we  use the phrase
punish non-conformity  to capture how  society might in-
directly burden individuals whose  voices  deviate from a
perceived norm.
   The  primary focus of our empirical analysis is judicial
outcomes-namely, which attorney prevails   at the Supreme
Court-this  emphasis motivates a selection puzzle rooted in
