Saddhamala wrote the other day about how we “catch” emotions from others. As she points out, this happens when you’re hanging around someone who is negative, and it brings you down, and that it even happens when we watch a movie!
So this is definitely a part of our experience.
You may not have realized, though, just how infectious our emotions are. The effect of one person’s emotions — whether negative or positive — can be measured as they ripple outward through our friendships and contacts.
Let’s deal with the negative first.
An important study by University of Chicago psychologist John Cacioppo showed that lonely people tend to share their loneliness with others. He uncovered this by looking at data from a large-scale study that has been following health conditions for more than 60 years.
You might be wondering: if lonely people aren’t in contact with others, how can they spread their loneliness? The thing is that loneliness is a state of mind rather than an absolute absence of social connections. Lonely people may be with others much of the time, but they aren’t able to connect. They feel disconnected and isolated even in social situations. And the people they are in contact with pick up on and share those feelings. But those feelings do of course affect relationships, and lonely people lose friends. Sadly, before their friends leave, they end up feeling lonely as well!
This is true for other negative emotions, too, such as anger and depression. It’s even true for factors such as obesity, criminality, and bankruptcy.
Now for the positive.
Another study by Harvard Medical School professor Nicholas Christakis and James Fowler from the University of California, San Diego, found that happiness also spreads through populations. One happy person spreads their joy to others. In fact, they could measure the increase in happiness as it formed a chain reaction that benefitted not only people’s friends, but their friends’ friends, and their friends’ friends’ friends. This effect lasts for up to one year.
How strong is this effect? It’s strong. If you’re happy, a friend living within a mile experiences a 25% chance of being more happy. One of your friends’ friends has nearly a 10 percent chance of increased happiness, and a friend of that friend has a 5.6 percent increased chance—a three-degree cascade. Compare that to, say, a $5000 income bump, which increases your odds of being happy by just 2%.
Every happy person in our world has a significant effect on many people around them, adding in a measurable way to the sum total of human happiness.
A study by Nicholas A. Christakis and others showed that the average lifetime of a contentment “infection” is 10 years, while the average lifetime of a discontentment “infection” is 5 years.
Also, this study showed that happiness spreads faster than misery. As Christakis says, “It’s pleasurable to be near other happy individuals and not near other unhappy individuals.”
Sometimes the quest for happiness is seen as being selfish, but it’s clear that that’s a shortsighted view. Our own happiness has an effect on others around us, and it’s almost an imperative for us to become happier if we want others to be happy.
As the Buddha said, 2,500 years ago,
Conquer the angry man by love.
Conquer the ill-natured man by goodness.
Conquer the miser with generosity.
Conquer the liar with truth.
When you consider how powerfully interconnected our world is (for example, on Facebook every person is, on average five connections away from any other person) it’s clear that this ripple effect is a powerful force for changing the world. Remember, one happy person raises the happiness of people — measurably — even at three degrees of separation, and possibly beyond.
This means each of us is more powerful than we may give ourselves credit for. Your happiness (or your grumbling) can affect the world. Use your power wisely!
