The Overton Window has to do with what policies are acceptable to the mainstream at any given time. There is a sort of Overton Window effect with all creative ideas.
You might approach your boss, or a client, with a brilliant idea. However, even the boss who loves creative solutions might not understand the idea if it’s “too unique.”
There is a sweet spot with introducing new ideas. Not so normal that it’s boring, but not so creative that it’s confusing.
Introducing brilliant or new ideas is like blowing a soap bubble. Be gentle and shift the window of acceptable ideas. If you push too hard, the bubble will burst.
