Sam Harris sometimes uses the word perfunctory on his podcast.
Perfunctory describes the way someone performs an action without thinking about it… Usually in an apparently non-caring, lackadaisical way…
(of an action or gesture) carried out with a minimum of effort or reflection.
In using perfunctory in a sentence, you could say:
“Finally, she completed her new Facebook user registration with a perfunctory agreement to the social network’s Terms and Conditions.”
