noun

perversity

per-VUR-suh-tee/pərˈvɜːrsəti/

The quality of deliberately going against what is reasonable or right.

Her perversity leads her to reject both the umbrella and the convenient gate.

A compact two-scene illustration shows the same woman pointedly rejecting two obvious, harmless conveniences: an offered umbrella in heavy rain and an open garden gate beside a muddy route through the hedge.
Etymology

The adjective's image of being turned away from what is right developed into being obstinately contrary. Perversity names this as a person's disposition or recurring pattern of conduct.
