The answer is fluid intelligence. Fluid intelligence refers
to the general ability of an individual to think conceptually, reason out,
identify different and confusing patterns and even solve problems. It also
includes discerning relationships with other people. This concept of
intelligence is used to explain intelligence in the field of Psychology. This
concept of intelligence was formed and developed by Raymond Cattell and his
apprentice John Horn in the 1970s and 1980s.
