counterproductive
UK: ˌkaʊn.tə.prəˈdʌk.tɪv | US: ˌkaʊn.t̬ɚ.prəˈdʌk.tɪv
adj. having the opposite of the desired effect; hindering rather than helping
The word combines "counter-" (from Latin contra, meaning "against") and "productive" (from Latin producere, "to bring forth"). It emerged in the early 20th century to describe actions that undermine intended goals. The logic is straightforward: if "productive" generates progress, "counterproductive" reverses it.

Excessive rules may prove counterproductive by stifling creativity.
