Ah I see. Insofar as UI/UX research resembles science, and it certainly often does, I agree that it would be better if it was public not private. But as much as I dislike corporations patting themselves on the back, I just don’t think it’s realistic to say they never innovate anything ever in designing a product.
Here’s an example: every part of the first iPhone in 2007 was already invented before its release. None of the core technology was new. But I think it’s hard to deny that Apple innovated in packaging it together in a useful attractive product.
