How To Use The Propinquity Effect To Win Friends
Propinquity. What a fun word. It means nearness: nearness in proximity, time, kinship, affinity and similarity. If you’re not careful, you’re going to find yourself over using this word, just like I do, in general conversation because it’s so much fun to say.
Propinquity Effect
As it turns out, I’m not the only person who enjoys using this word. Behavioral Psychologists use it to describe what they call the Propinquity Effect, which theorizes that the more we interact with others, the more likely we are to like and become friends with those individuals.

Westgate Student Appartment
This theory was based on a study done in 1950 in the Westgate student apartments on the campus of MIT in Cambridge, MA. The researchers discovered that the students tended to like and make friends with their immediate neighbors. They also discovered that the students who lived near the ground floor staircases and mailboxes had friends on both floors due to their proximity, or propinquity to the entrance of the building.
Examples of the Propinquity Effect
You can easily find examples of likeability based on propinquity everywhere you look. Think of your best friends in school. With the surname Sommers, my best friends had names like Schnurr, Schulte, Smith and Sontag. These were the people I sat next to in class because we were seated in alphabetical order.
My best friend when I was a child lived three houses from me. The people I spent time with when I first moved to Atlanta were the people I worked with and lived next door to in my apartment complex. After purchasing my first home, I found that I was spending a lot of time with my neighbors and inviting them to my parties. The propinquity effect has been alive and well in my life from my birth and I don’t expect that it will stop any time soon.
The opposite is also true. When you don’t come into close physical contact with someone, you tend to loose contact with them.

The Allen Curve
During the late 1970s, Thomas J. Allen, another MIT professor, undertook a project to determine how the distance between engineers’ offices affects the frequency of technical communication between them. The result of that research produced what is known as the Allen Curve.
What Professor Allen discovered was that there was a strong correlation between physical distance and the frequency of communication between workstations. The farther away people were from each other physically, the less likely they were to communicate with each other using all forms of communication including face-to-face, telephone, email, etc. In mathematical terms, he discovered an exponential (huge) drop off in communication based on distance.
We are more likely to like and befriend people with whom we have close physical contact. We are also more likely to loose touch with the people who we don’t see as frequently. This is the primary reason our friends change as we grow through life.
Propinquity Effect In Action
If you want to befriend someone or give him or her the opportunity to like and befriend you in return, it’s in your best interest to find a way to be in close physical contact. Here are a few suggestions that will help you get likeability through propinquity flowing.
Start by identifying the people with whom you want to develop a relationship. Do some research and find out where they spend their time and what they spend their time doing. This should be relatively easy if the person you’re targeting is your spouse or child.
Make an effort to hang out at the same places they frequent. Try to bump into them or make arrangements to meet up with them at lunch or after work. The more they see you and communicate with you, the more likely they are to like you.
If you’re trying to win over a customer, your success is going to be in direct proportion to how frequently they communicate with you in person. The more time you spend together, the greater the chance they’re going to like you and want to work with you.
It’s also important to remember that the Propinquity Effect is not just about being in close physical contact. It’s also effective when the propinquity has to do with affinity and similarity. The more similar your opinions, interests and attitudes, the more likely you will like, and be liked by others.
When it comes to likeability, nothing could be easier than taking advantage of the Propinquity Effect. All you have to do is be in the same vicinity of the individual you want to build a relationship with and let the communication happen naturally. Nothing could be easier.

All things being equal, experts generally agree that we tend to like competent people especially when they become relevant in our lives. This includes our parents, teachers, doctors, electrician, investment broker, auto mechanic, etc. The opposite is also true. As much as we are attracted to competent people, we are repelled from people who are candidates for the Darwin Awards.
Earl Nightingale, the inspirational author of “The Strangest Secret,” noted that anyone could become an expert in a very short time. His premise was that if you focused on learning any single subject for one hour a day every day for a year, it would be the equivalent of going to class for eight hours a day, five days a week for almost two and a half months. If you did the same thing for five years, it would be the equivalent of going to class every day for a year.
There is a huge credibility gap when people or things don’t look like what you expect them to look like. You may remember the crash of Value Jet flight 592 on May 11, 1996. The flight was en route from Miami to Atlanta (a route I often flew) when the low cost carrier went down in the Everglades killing all 110 people on board. The thing that immediately stuck me when I heard about the accident was a promise I made to myself just a few months earlier.
As I child I was interested in learning how things worked. On any given day you could walk into my bedroom and find what started out to be a perfectly good transistor radio, toaster or cuckoo clock sprawled out in little pieces on my desk. I was so curious about how these things worked that I decided to go to collage and become an engineer.
I started by introducing myself to 10 new people everyday with the purpose of learning their name along with something interesting about them. It was not easy at first, because I didn’t know how people were going to respond to my open and inquisitive nature. What I discovered, however, was that virtually everyone I met was delighted to have an opportunity to talk about themselves.
Watch Out for Soft Spots
The state of Hawaii (and most other states) will not issue a drivers license to anyone until they’ve attend an approved driving class, driven 50 hours on a temporarily permit with a qualified driver and passed a comprehensive written exam and an on-road driving test. Then, in order to keep your license, you must be able to prove to the police and other drivers that you understand and practice the rules of the road. But, there are absolutely no rules or training required by the state if you want to have and raise children.
Study after study shows that likable children and likable adults are happier, healthier and they live longer than their counterparts. These studies do not show the same results for smart people or rich people even though these are the skills we emphasis in school. Again, there is nothing wrong with being smart and rich; both are great. But imagine if you could be smart and rich and happy and healthy and live a longer more productive life at the same time. That sounds like success.
We dislike the people we hurt
Recently a friend of mine told me a story about an encounter she had with one of her co-workers when she accepted a job as the manager of IT at large technology company. On the morning of her first day of work, she attended a staff meeting where she was introduced to the other managers.
My younger son is a very handsome guy. When he was 20 years old he wanted to get a tattoo on his wrist. Now, I don’t have anything against tattoos; as a matter of fact, I’m planning to get one myself before long. I didn’t feel it was my place to discourage him from getting his tattoo, but I did feel it was important that I help him understand how it could impact the way people treated him.
Maybe you’re one of those people who haven’t paid attention to personal grooming. Maybe you’re one of those people who don’t care about your appearance. Maybe you believe that in order to express yourself honestly you aren’t going to change the way you look or dress. That’s your prerogative.
It’s been five years since we started production on the Recognized Expert Marketing Show. Almost 200 programs later, I’ve had a chance to step back and reflect upon my relationships with the marketing, sales and self-promotion experts who have appeared on the show.
The second reason we have a hard time with know-it-alls is because we like ourselves more when we enhanced the lives of others. Know-it-alls don’t give us that opportunity. They seldom allow us to share our thoughts and opinions and when we do, they either ignore us or they disagree with us.
