The extrovert bias in day to day business and personal dealings with people can be countered if we take the time to appreciate that 25% of the workforce is likely introverted, i.e., energized by what goes on inside their heads rather than by what is in their environments. "Innies" are undervalued as employees,as creative thinkers and problem-solvers, and as talented people. Recently discovered British singer, Susan Boyle, would be a clear example of this. "The Introvert Advantage" helps innies cheer for themselves and helps "outies" gain insight into the non-dominant way of being and doing in the work place and in life in general. Reading this book should stimulate some changes in the way HR departments frame interviews, the way supervisors supervise, and how peers relate to one another.
