DictionarybelieMisleading appearance
verb

belie

bih-LYE/bɪˈlaɪ/

To give an impression that hides or contradicts the truth.

The box's polished exterior belies the decay hidden inside.

A brightly polished wooden box appears sound outside but an open cutaway reveals badly decayed interior; outward appearance gives a false impression, no deceptive person stereotype.
Etymology

Originally meaning “deceive by lies,” belie also describes misleading appearances: something can give a false impression without anyone making a false statement.
