Cognitive disonnance is double edged. And often unnecessary.
Cognition bias is a product of it.
They refer to realities - not just other terminology.
Semantics authority tactics won't change that.
Those two huge behavioural factors would probably account for refusal to accept the unknown as such - with no assumptions about same necessary.
But - another factor: when behaviour is discussed - that often leads to that behaviour itself.
So I could expect there'll now be a series of tacital posts manifesting that behaviour.
Which everybody can skip if they want.
Until a good system of units to refer to computer hardware speed is brought into the conversation - then spam about nodes and its offspring will continue.
Up to 500 posts here. But this forum competes with the other one.
Anyway - the info is there for those who want to inform themselves about cognitive disonnance and resulting cognition bias (which is far beyond and more general than 'bias and prejudice' like in politics and the like)
The two behavioural factors can be googled. Articles.
But after that - thinking helps too. And articles as opposed to dictionary.
Up to the readers.
Chess Will Never Be Solved. Why?

"too many possibilities with each move"
There are only 2 to 4 relevant possibilities with each move.
Initial position 1 e4, 1 d4, maybe 1 c4, 1 Nf3.
On 1 e4: 1...e5, 1...c5, maybe 1...e6, 1...c6
On 1 d4: 1...d5, 1...Nf6, maybe 1...e6, 1...c6

yes
i agree

There are only 2 to 4 relevant possibilities with each move.
Really few, compared to the irrelevant comments.
yay an IM commented on my forum

Chess is a difficult game with too many possibilities with each move.

"There are so many possibilities"
++ There are 10^17 legal, sensible, reachable, and relevant positions.
That is huge, but existing computers and humans can solve it in 5 years.

"chess ceases to be fun when humans can calculate all the variations in it"
++ Computers can calculate all positions in 5 years, but humans cannot memorise all of that.
Chess may become even more fun. Assume that chess is 100% analysed and that all 20 first white moves lead to a draw. Then we would see all of these 20 first moves played instead of just 2 or 4.

I guess :/

Can chess be solved? In theory, chess may be solved in the future because the rules create a closed, predictable system. In practice, however, chess currently cannot be solved because it’s beyond the capacity of any human mathematicians and beyond the capabilities of today's computers.
There is some unwillingness from some about the business of acknowledging that something isn't known.
The nature of not knowing something.
That in such situations - it doesn't follow that assumptions are then necessary or the slightest bit productive.
Perhaps cognitive disonnance and its cousin - cognition bias - are just too strong.
So strong that 'Hey it isn't known. Nor is that other thing. Stays like that and maybe for a long time' isn't supposed to survive.
But there's quite a list of realities that are exactly like that.
