Is being a Highly Sensitive Person adaptive in our culture?
See http://www.hsperson.com/pages/test.htm and other parts of Elaine Aron's HSP research for a background in Highly Sensitive Person research. There is also a book "Quiet - The Power of Introverts in a World That Can't Stop Talking" by Susan Cain. However this book confuses HSP characteristics with introvert characteristics. Aron believes they overlap with 70% of HSPs introverted and 30% extroverted.
