A term I once read that covers consensus terminology and when methods and theories need to overlap to enable collaboration, is "Intersubjectivity". Like agreeing that blue is the name of the colour of the sky, and "wet" means being soaked with or covered in water. And water is that stuff that falls out of the sky from time to time and makes plants grow. And plants are generally green. Darkness is black. etc.

Intersubjectivity is the only reality we can both apprehend and describe and share. So it is fallacious to talk about objectivity. We can only, like a blockchain, share the data, replicate the experiment, and add our confirmation to the chain of data. What it is may be something entirely other, but we cannot describe what we have no words for, and we cannot communicate our description unless others use the same words for experiences that are demonstrably analogous.
