You have to understand that your own perceptual experience is not identical to that of all other humans. Without recognizing that, we will inevitably end up talking past each other endlessly and writing each other off as { hallucinating, lying, exaggerating, etc } for one of us claiming to perceive something important that the other does not.

It would be no different than arguing about whether we need all three primary colors (red, green, blue) with someone who is colorblind (and unaware of this). Or like arguing whether speakers benefit from being able to reproduce a certain frequency, with someone who is partially or fully deaf at that frequency. And I truly mean no disrespect to anyone with different perception abilities in these or any other domains.

Recognizing that large differences exist here is essential to make sense of the reality - that something that seems completely unimportant or barely noticeable to you, could actually be a hugely obvious and important difference to many others (whether it’s a certain screen refresh rate, the presence of a primary color you cannot perceive but others can, an audio frequency you cannot hear but others can, or otherwise).
