What if I told you the secret to happiness and success is a line and a number?

The line is called the Losada line and the number is 2.9013 which is the ratio of positive to negative interactions you need to have to be happy and successful. Simply put, you need to have at least three positive interactions to every negative one to be happy.

The Losada line and ratio came out of a study done in 2005 by two psychologists, Marcial Losada and Barbara Fredrickson who analyzed the interactions of management teams and how successful they were. The mathematical formula they used was subsequently challenged and discredited by some experts, but many psychologists still cite their work and adopt the principles of the Losada line in sport, business, and to help individuals achieve positive mental health.

They found if teams generate more than 2.9013 positive feelings, emotions or interactions to every 1 negative feeling, emotion or interaction, the team has positive energy needed to feel good about themselves and flourish. A 5:1 ratio is a culture everyone wants to be part of. Teams below the Losada line of 2.9013 have a deteriorating culture, and at 0.73 to 1, the team culture destructs.

In another study, Dr. John Gottman looked at similar research in marriages. Gottman claims he can predict divorce with 90% accuracy by counting the number of positive versus negative interactions a couple has.

In marriage, the magic ratio is 5:1 (why the ratio is higher in marriage is an interesting question, presumably because marriage is hard and there are two individuals’ happiness at stake!)

Happy couple have at least 5 positive interactions for every negative one. You can read more about Gottman’s study and the types of positive interactions between happy couples here.

This week’s #HappyAct is to take the personal positivity test and strive to increase your personal to negative interactions to 3:1 or higher. Gottman also has a quiz on his website called “How Well Do You Know Your Partner” (note you have to provide your email address to get the results emailed to you but a summary pops up on the screen as soon as you provide your email).

And don’t worry if you score low initially on the personal positivity test. I expected to because I’m at home nursing a broken ankle right now. Think of it more as a check in with how you’re feeling, then start working towards improving your positive interactions and on a path to better mental health and happiness.
