If you are wise and prone to evaluating information before making a decision, you possess sagacity, the trait of solid judgment and intelligent choices. And if that is indeed the case, then good for you! We need more sound thinkers.
The Latin word sagācitās is the great-granddaddy of our word sagacity, giving it the meaning "wisdom." Just remember that it contains the word sage, which means "wise one" — our wise ancestors were called "Sages." But before we get too puffed up, we need to remember that in the 17th and 18th centuries, sagacity meant "the acute sense of smell in animals." How humbling. Still, if you display sagacity, you can sniff out a good idea from a bad one.
