This is a perfect description of YEC:
Because once the paradigm was established and accepted there was nothing to do but build upon it and within it. It has become an entrenched assumption or presupposition. There is enough seeming evidence, or at least plausibility, to keep the system going, as long as tge few best bits of evidence are emphasized over and over and the difficult areas are sidestepped, which is very easy to do with a theory that is unprovable in the direct ways the hard sciences are provable.
Unprovable because the whole thing is an edifice of interpretation upon interpretation, none of it can be replicated, it can only be interpreted. You can't replicate the burial of dinosaurs, all you can do is interpret what you think must have happened, and in that enterprise you are limited by what has already been accepted, so you fit your bit of understanding into the already-constructed edifice. You add your interpretive plausible bit to the whole edifice and just keep building, although it has no foundation in actual fact, it's all mental conjurings. The whole thing is a gravity-defying reality-defying multiplication of interpretations floating some distance above planet earth. You have the illusion of science, the illusion of evidence, you mentally manipulate mental figments as if they were realities. It's all very convincing if you are entrenched in the system yourself.
