Thank you for commenting! Yes, truth units are "subjective" in the conventional sense, although please let me explain further.

Let's say I'm one of 10 people with iPhones. I look at my watch. It says the time is 5:15 pm. My truth unit is "it's 5:15" and my test/evaluation was me looking at my iPhone. The other 9 people look at their iPhones at the same time I do. Each of them now has a truth unit: "it's <whatever time I saw>." Hopefully they all saw it was 5:15.

My truth unit is my validation, and their truth units are their validations. If each of the 10 of us were on different planets, we would have no cause to question ourselves.

But if the 10 of us were about to go out to dinner together, and our truth units were for different times, then we would have to deal with those discrepancies.

In the situation I'm describing, the concepts of objective and subjective don't really apply.

It's our social practice for us to treat our individual beliefs about what time it is as "subjective" and our consensus (after exploring and analyzing the discrepancies) would be treated as "objective."

The word "objective" suggests it's 5:15 (or whatever) in reality separate from our truth units. That meaning doesn't exist in truth units theory.

It's like Schrodinger's cat -- the idea that the cat is alive or dead before you open the box doesn't exist in quantum mechanics. It's not that there is no reality, it's just that such reality is not something humans can access.
