Different is strange, awkward and uncomfortable. It challenges people’s beliefs and makes them feel uneasy.
Most people avoid the different. The questions: “Is she a good fit?” and “That’s how we do things around here.” reveal this attitude.
They want the things to remain the same.
It is easy to agree with somebody if you share the same set of values.
Apple fans understand and agree with other Apple fans. Programmers understand programmers. Business people understand business people. It is when the cross communication occurs, that’s often problematic.
Surrounding yourself with like-minded people to protect your beliefs is not much different from closing your eyes and shouting the story you keep telling yourself.
