In summary, introverts need quiet and space to do their work. They can only cope with loud noise and lots of people in short doses. If they can't work and live in conditions that support their preference they will get sick, be stressed and far less productive. And, if the extroverts of the world don't take time to listen or give them the opportunity to contribute, they miss out on many well-considered pearls of wisdom that in some cases would have saved serious consequences.
Following is just one of the stand-out points that hooked me and I'll share others in coming weeks.
A cultural change
Cain charts the progression in American society over the last 100 years from the Culture of Character to the Culture of Personality and the rise of the Extrovert Ideal. Being able to speak up and out confidently has become an expectation, even in educational institutions of all levels. For example many US universities, including Harvard, encourage and edify quick and assertive answers over quiet slow decision-making. 'We see talkers as leaders'. And so the heads of many organisations have extrovert tendencies.
You'll read many case studies of introverts who have been marginalised, side-lined and ignored while loud confident leaders have taken their companies to ruin. Examples include Enron and a number of the institutions caught in the 2007 Global Financial Crisis.
Have you seen the same thing happen in your world? Quiet people will offer opinions if given the opportunity. Is everyone listening to them?
Watch for my next article in two weeks where we'll dig into some more eye-openers from this book.
