Practical Intelligence

The particular skill that allows you to talk your way out
of a murder rap, or convince your professor to move you
from the morning to the afternoon section, is what the psychologist
Robert Sternberg calls "practical intelligence.,,
To Sternberg, practical intelligence includes things like
"knowing what to say to whom, knowing when to say it,
and knowing how to say it for maximum effect." It is procedural:
it is about knowing how to do something without
necessarily knowing why you know it or being able to
explain it. It's practical in nature: that is, it's not knowledge
for its own sake. It's knowledge that helps you read situations
correctly and get what you want. And, critically, it is
a kind of intelligence separate from the sort of analytical
ability measured by IQ.
