Morphology

rationalist = rational (semi-transparent) = rational + ist

Formally derived from 'rational' + '-ist', but the sense referring to a specific contemporary online movement has specialized connotations not predictable from the components alone.

Etymology

Rationalist comes from the Latin root ratio 'reason' or 'calculation'. A helpful way to remember the modern online rationalist is to think of people who treat beliefs like numbers to change when new facts appear, so they focus on careful, evidence-based thinking.
