It is useful to understand the differentiation between the various "Qs":

IQ > EQ > SQ

IQ (Intelligence Quotient) - a measure of an individual's intellectual, analytical, logical and rational abilities. (Steven Shien J. and Howard E. Book, The EQ Edge, (2006))

EQ (Emotional Intelligence) - an array of non-cognitive(emotional and social) capabilities, competencies and skills that influence one's ability to succeed in coping with environmental demands and pressures (Reuven Bar-On, BarOn Emotional Quotient Inventory (EQ-i) Manual, (1997))

SQ (Social Intelligence) -a shorthand term for being intelligent not just about our relationships but also in them (Daniel Goleman, Social Intelligence, (2006)

Why is this area getting so much attention, particularly in the business area?  The following attached summary of benefits various organisations gained from basing certain business decisions on EQ is quite revealing as is the study showing how to promote Emotional Intelligence in organisations.

The good thing about both EQ and SQ, but not IQ, is that with awareness and training, it can be enhanced and developed.
