cold-bloodedness
Lack of warmth
Cold-bloodedness is the quality of being unfeeling or ruthlessly calculating.
A person who acts with cold-bloodedness shows no emotion or mercy: The cold-bloodedness of the murder shocked even veteran detectives.
The term derives from the old belief that cruel people had cold blood, while passionate people had hot blood.
In biology, cold-bloodedness refers to animals whose body temperature varies with their environment, though scientists prefer the term ectothermy.
