I thought this was a nice summary in the American Way magazine (5/1/09). It also talks about Jennifer Kahnweiler’s book “The Introverted Leader: Building on Your Quiet Strength“.
I think understanding this about your team and peers is critical. It’s also important just to understand that recepients of your messaging may analyze the information very differently. From a quick scan on Google, I found that 25% of the overall population is considered introverted.
Thanks George – Glad you liked the chart…I like your reinforcement of the point that we need to “flex” our messages!
