Do Supreme Court justices actually go through and read every amici curiae?

[Thank you for being a friend...]

I just read an amici curiae supporting Gavin Grimm, whose landmark trans kids case goes to the Court at the end of the month.  I find it hard to believe that Roberts, Alito, and Thomas are really going to sit down and read the science behind trans people and fetal brain development and gender biology.  I think their minds are already made up of how they're going to vote - against Gavin.

Really the decision has to come down to Anthony Kennedy, once again.  This guy is like the only vote that matters on that court anymore.

Kennedy, Sotomayor, Kagan, Breyer, and Ginsburg (5) vs. Roberts, Alito, and Thomas (3)
