About twenty-five years ago, Dr. Howard Gardner came up with a new theory about intelligence. He proposed that people were much more complex than what could be revealed in an IQ test or any other standardized testing model. He argued that different people have different strengths (i.e. intelligence types).
Before this time, it was generally believed that intelligence was a single entity that was inherited. Today, most researchers believe the opposite; that there exists a multitude of intelligences that are quite independent of each other. It is also now believed that each of these intelligence types comes with its own strengths and constraints.
