Seen that image of all SUVs which look alike? While regulation and safety play a role, we see the same design over and over because most people want something similar to what everyone else already has. We like different, but not too different.
741 Is Design Dead? No, We Just Don’t Like “Different”

As social creatures, we humans crave a sense of belonging and community. We want to feel like we’re part of something bigger than ourselves and that our peers accept our opinions and values. But we also want to stand out and show off our unique personalities. So it’s a balancing act between fitting in and being our person.
At the same time, we’re also scared of being too different. Nobody wants to be labeled as a weirdo or an outcast. So, we try to toe the line between being different and fitting in. Of course, we express ourselves through clothing, language, and actions, but we still try to stay within the bounds of what’s considered “normal” in our social group.
This balance is something we see not only in humans but in other animals too. For example, birds often have unique behaviors and feathers but still follow their flock’s or species’ norms.
Overall, the desire to be different, but not too other, is a natural and complex part of being human. It’s all about finding that spot between standing out and fitting in. By embracing our individuality while still respecting the social norms of our group, we can create a sense of belonging and uniqueness that enriches our lives and the lives of those around us.
