Think You're Well Connected? Stop Fooling Yourself

You read a lot. You’re informed daily through Twitter, various blogs, and a few subscriptions. Your network is very large, and is made up of people who also have large networks. With technology at your fingertips, you are extremely well informed.

You’re fooling yourself.

Humans want to know what others think, and we’re especially persuaded when information is verified by different sources. The problem is that our “different” sources often tap the same information. You hear something from a Twitter feed that you like, that is confirmed on a blog, that is confirmed yet again by a video of a Ted talk. But what if each of these got their information from the same source? You are all recycling one single datum! It is bad to be poorly informed, but it is much worse to be poorly informed and not realize it.

For example:

“As CEO, I make sure I am in the thick of it. I stay right in the middle of things: product development, engineering, marketing, sales – they all keep me in the know.” So said the CEO of a software startup where I was conducting interviews. I met with him four times over four months, as he shaped the strategy of his budding company. He was surprised when they failed. All his information sources agreed that his strategy would win.

But let’s take a closer look. I asked everyone in his company to tell me whom they turned to for work-related advice and information. Using the matrix of these information flows among everyone in the firm, I mapped the company’s information network here - where the squares are people and the lines are their communications:


As you can see, this company's communication network is dense and saturated, with plenty of paths for information to get around. But that is precisely the problem. Throw one single datum into this company and it rapidly cycles throughout the whole system over and over and over. The central people in the middle – including the CEO – are no better informed than anybody else in this network; they just think they are. But they are simply hearing the same information as it gets recycled over and over apparently from different sources. No wonder they convinced themselves that their strategy made sense. They got the illusion of a second opinion without ever really getting a second opinion.

The solution?

Gather information from those who do not communicate with one another. In fact, you want to gather information from entire networks that do not communicate with one another. Truly rich and diverse information comes only when you hear, separately and independently, from “worlds” that do not overlap: From different parts of the earth, different economic sectors, different social demographics, different religions, languages, ideologies and cultures.

But gathering such varied data is difficult, and it is getting more difficult because of the IT revolution. Twitter will suggest that you listen to people who listen to each other. Amazon will suggest that you read something very much like what you just read. Even your search engine will try to make sure that you get results that are similar to the ones you clicked on last time. If you go with the flow, you’ll end up hearing the same narrow view recycled repeatedly – yet you’ll think you did your due diligence.

Don’t fool yourself.
