Trope-a-Day: Becoming The Mask

Becoming the Mask: Played straight with gnostic overlays, the special kind of downloadable knowledge/skillset that overlays values or other personality aspects onto the person using them (see, for instance, the constabular overlay and objectivity overlay mentioned under Incorruptible Pure Pureness).  Long-term users of given overlays tend to find themselves adopting the value-sets, personality traits, etc., encoded into the overlay.

This technology is also used therapeutically, in the ultratech version of cognitive therapy.  Wearing Cheerfulness 1.17 around everywhere for a year or so genuinely will train you to be a happier person.
