While there are a plethora of intellectual points for discussion, 'practical intelligence' in my opinion, is the new key term to take away from Gladwell's book. PQ is a term that psychology Robert J. Sternberg proposed, when he argued that there are three intelligences in human cognition:
(1) Analytical intelligence - the ability to analyze and evaluate ideas, solve problems and make decisions
(2) Creative intelligence - involves going beyond what is given to generate novel and interesting ideas
(3) Practical intelligence - the ability that individuals use to find the best fit between themselves and the demands of the environment.
The three intelligences, or as he also calls them three abilities, comprise what Sternberg calls Successful Intelligence: "the integrated set of abilities needed to attain success in life, however an individuals defines it, within his or her sociocultural context." While society tends to have bought into the idea that innate talent, through such test devices as IQ tests, can predict the success of a person, Gladwell re-examines this piece of wisdom, and argues otherwise. This book will be useful for anyone with a curiosity for success. It gives us a better, more complex, inquiry into what fuels success. And it's not just about brains, you know.
