noun
imprudence
im-PROO-dunts/ɪmˈpruːdns/
Lack of sensible caution or practical judgment.
Stepping onto the visibly cracked ladder shows the man's imprudence.

Etymology
The base means 'to foresee,' so imprudence originally expresses a lack of foresight. That connects heedlessness about what may happen with the present sense of poor judgment or insufficient caution.
In context
