Maybe this is a cognitive or neurodivergence issue. Most intelligent people can filter without any conscious work.

I might act different if I am at a house party versus playing with my newborn, but I consider those both to be me, just in different situations.

Similarly, if I'm playing chess, I don't following the rules as contrary to my identity. I see myself as a flexible and adaptive problem solver.

I think you are on to something though and can imagine a person having a different self-identity that is less adaptive.

I believe that this is the case where the "self" needs some more work, as in it is not well-adapted enough to its total environment yet. This can be due to a myriad of reasons, neurodivergence or other neurological problems are often a possible culprit due to an altered cognition, but don't need to be. If someone just doesn't give a crap or doesn't understand the consequences of some kind of behavior (or the lack thereof) in some situation, they will not be inclined to develop a more appropriate behavior for that situation.

I think that's a good way of putting it. It explains why that particular type of Behavioral inflexibility struck me as immature or coddled.
