While intelligence is the ability to process information, sagacity is the ability to sniff out the reality of a situation. The word occupies a unique space in the English language, sitting between wisdom and cunning. It is less passive than wisdom and more ethical than shrewdness.
According to researchers at the University of Cambridge, long-term decision-making often relies on the synthesis of experience and pattern recognition. This is exactly what a sagacious person does.
