Over the last century or so, intelligence has been defined in many different ways.
Theories of multiple intelligence contend that intelligence cannot be measured by a single factor.
Human intelligence is shaped by both internal genetic factors and external environmental circumstances.
Intelligence testing has evolved over time as researchers continually seek the best method for measuring intelligence.
IQ tests are used to measure human intelligence quotient as measured against an age-based average intelligence score.
Standardized tests are identical exams always administered in the same way so as to be able to compare outcomes across all test-takers.
Intelligence tests and standardized tests face criticism for their uses and applications in society.
