People learn by comparison.
They learn by comparing new things to the things they already know. That’s why redefining a category is much easier than creating a new one.
When you position your product in an existing category you’re essentially saying “it’s like something you already know but better”.
When you try to create a new product category you’re essentially saying “it’s like nothing you’ve ever seen before”.
That’s a provocative statement, but hard to learn by.
