We borrow the textual data of the conversations in the United States Supreme Court pre-processed by (Hawes, Lin, and Resnik 2009; Hawes 2009 ) and enriched by (DanescuNiculescu-Mizil et al. 2012) including the final votes of Justices. The linguistic coordination is systematically quantified by<cite> (Danescu-Niculescu-Mizil et al. 2012</cite> ) and the arguments follow the principles of exchange theory examining behavior dynamics in low and high power groups (Willer 1999; Thye, Willer, and Markovsky 2006) : Lawyers tend to cooperate more to Justices than conversely and demonstrate strong linguistic coordination in their speech.
