Recklessness (psychology)
Recklessness (also called unchariness) is disregard for or indifference to the dangers of a situation or for the consequences of one's actions, as in deciding to act without stopping to think beforehand. Aristotle considered such rashness as one end (excessive) of a continuum, with courage as the mean and cowardice as the deficit vice.
