Positivity: Top Notch Research Reveals the 3 to 1 Ratio That Will Change Your Life by Barbara L. Fredrickson, PhDWhy Marriages Succeed or Fail: And How You Can Make Yours Last by John Gottman, PhD
After extensive observation, Gottman and his team of researchers at Univ. of Washington have been able to predict with an accuracy rate over 90 % which marriages will succeed and which will fail. One of their findings is that in a marriage that lasts, there is a 5 to 1 ratio of positive to negative moments. In comparison, Fredrickson and other researchers have found that in order to do well, people need a ratio of 3 to 1 positive, heart felt thoughts and feelings to negative ones; 4 to 1, etc. in order to flourish.
