Human evolution vis-a-vis the changing role of human brain

Daniel Pink touches upon this aspect in great details in his book “A Whole New Mind”

Human civilisation in developed economies has moved on through the following stages:

Agricultural Age-> Industrial Age-> Information(Knowledge Worker) Age-> Conceptual Age

The role of left brain and hence L Brain Thinking which defines IQ held prominence till the Information Age.

In the Conceptual Age though IQ alone is no longer sufficient and must be complemented by EQ powered by the Right Brain.

Hence R Brain thinking will rule in this new age.
