Recklessness

Etymology

From Old English "receleas," from "reccan" / "recc" (to care, heed) + "-less." The verb "reck" — to care — has nearly died, surviving almost only in "reckless": literally, without heed.

noun · /REK-lis-nis/
Heedless disregard for the consequences of one’s actions.
What it names
Acting without weighing the risk — not ignorance of danger but indifference to it.
Example
The firm’s recklessness with customer data was not a breach of the rules but the absence of any.
Related idea
Rashness is acting too fast, without thinking; recklessness is acting without caring what happens. The rash misjudge the risk; the reckless simply don’t mind it.
