There are likely other human intelligences beyond those identified by Howard Gardner. For example:
1. Daniel Goleman (author of Emotional Intelligence) argues for emotional intelligence and social intelligence, both of which are essential to getting along with the world around us and the people in it.
2. Robert Cooper (author of The Other 90%) talks about the intelligence of the enteric nervous system, indepentent of but also interconnected with the cerebrum, which give us valuable iformation through gut reactions.
The bottom line is that human intelligence is diverse and multifaceted (to use a Ken Robinson phrase). Unfortunately, some very intelligent human beings have perceived themselves to be very unintelligent simply because their diverse and multifaceted type of intelligence has not been high on the somewhat artificial list of societally-rewarded abilities. That makes it even more important to ask the right question, which may be, "How are YOU intelligent?"
