Actually, āI couldnāt care less,ā may be an accurate expression of what some one means, e.g., I care so little that I could not care any less. Therefore no contradiction ā the expression means what it says.
On the other hand, if one said, āI could care less,ā that would mean there is room for me to care even less, which may contradict the intended meaning.
The ācouldnātā form is the only one that makes sense in the context the expression is generally used.
