How to read this

Martin–Quinn scores place each justice on a single liberal–conservative dimension, estimated from their votes across terms, with scores allowed to shift from one term to the next. Higher is more conservative. The shaded band is the credible interval: wider when the record is thin, especially in a justice’s first terms, and narrower as votes accumulate.
