Do you believe in karma?

Research shows that most of us do, whether we admit it or not.

When we want something and we’re unsure whether we’ll get it, we become more helpful:

You feel that if you do something good, fate will look on you fondly and grant your wishes.

This isn’t utter delusion or pollyanna foolishness.

Research into social networks is showing karma may be quite real.

The people who surround you dramatically affect your behavior without you even realizing it.

You know the “Six degrees of Separation” idea or the more popular “Six Degrees of Kevin Bacon”?

(I explored this concept in a post about Paul Erdos — the undeniable center of the mathematics world.)

Behavior is influenced three degrees out. So you are affected by the whims of friends of friends of friends — and similarly, they by you.

Political views, weight gain, smoking and even that very very important thing, happiness, are all influenced by strangers.

Have a depressed roommate? You’re more likely to become depressed. Moods can be like infections.

Happy friends make you 15% more likely to be happy.

Even if a friend of a friend of a friend becomes happier, that means a 6% chance you will become happier.

Neat trick but 6% may not seem like a big deal to you.

Guess what? You’re wrong.

Making Friends = Making Happiness

Would $10,000 dollars make you happier? I’ll assume you’re nodding. Research shows 10K only provides a 2% increased chance of happiness.

So the happiness of people you have never met — and may never meet — is three times as powerful.

A happy friend increases the likelihood of you being happy by 9%. An unhappy friend means a 7% decrease.

You don’t need a degree in accounting to figure out what that means: overall, more friends = more happiness.

Spending time making friends has a higher happiness ROI than time spent making money.

The Best Way To Be Selfish Might Be Selflessness

You probably know where I’m going with this whole science of karma thing now: you can totally rig the system.

With the effect spanning three degrees, there’s a good chance making most people in your daily life happy will flow back to you.

Christakis and Fowler found that if a friend became happy in the past six months there’s a 45% chance your happiness will increase.

At the very least, working to keep your friends happy protects you against “infection” by unhappiness.

Want to be happier? The best way to be selfish about happiness is looking like selflessness.

Introduce Friends To Friends

Unsurprisingly, people at the periphery of a network have fewer friends and are more likely to be lonely.

And yes, that loneliness can flow back three degrees to you. (And no, you can’t easily track these people down and kick them out of your network.)

Know what you can do? Introduce your friends to other friends.

Like I said: happy friends means 9% gain, unhappy friend means 7% loss. All other things being equal, I’ll take those odds in Vegas any day.

This strengthens the network, and selfishly increases your chance of staying happy.

Via Connected: The Surprising Power of Our Social Networks and How They Shape Our Lives:

The idea of karma has been around for thousands of years and, if you think about it, back then people knew very few strangers.

Three degrees of separation was all that the vast majority of people had. And that’s still true for many of us.

As I’ve posted before, friends are the key to happiness and the best way to improve your life is through relationships.

None of this costs money. None of it is hard work. It can be as easy as sending an email.

And, studies show, it has a better chance of making you happy over the long run than $10,000.

Seriously, what the hell are you waiting for?
