People (especially those who are excessively conformist) tend to regard creative people as unusual. This is one reason why people have the misperception that geniuses tend to be weird. It's because they don't necessarily understand the inquisitive and creative mind.
This can be a problem in the workplace, though. I'm sure we've all heard stories about how employees who seek creative solutions are ignored or greeted with ridicule. When others are used to doing things in a certain fixed way, adopting a different approach can simply seem foolish.
I remember working on a robot back in my grad school days. We had a problem with teaching it to pick up a certain part, so I proposed adding a sensor to the gripper. Immediately, one of my grad student teammates shot back, "Too much mass" -- the idea being that this sensor would weigh too much to be useful. Mind you, it was an extremely lightweight optical fiber sensor, so the robot would have had no problem carrying it around. This was a heavy-duty industrial machine, after all, more than capable of lifting several kilos. This student had locked his mind into a particular path though (using computer vision for error detection), so he immediately dismissed any other solutions.
When I pointed out that the sensor weighed next to nothing and that the robot had plenty of payload capacity, he backpedalled. All of a sudden, he changed the nature of his objections. "Well, how would we route the fibers?" he asked, or "What about the I/O capabilities?" Now, I'm not saying that those weren't valid considerations; they certainly were, athough hardly insurmountable. My point is that this shows that he had not been voicing principled objections; rather, he had started out with a familiar approach in mind. This kind of familiarity can cause people to reject creative approaches simply because they are different.
