People have limited time. They demand that things be made simple. Sometimes things can only be made so simple, and sometimes 'simple enough to get across' is alas 'too simple to convey the real meaning'. I'll put some examples here.
Explaining Invisible Walls
Consider this example of an attempt to explain Invisible Walls:
Why I can't get a job.
Losing a job is bad. Thus a job, being a route to losing a job, is potential route to bad stuff, and hence is a source of potential anxiety.
It is the same with the myriad anxieties over performance, and questions like 'can I do the job well enough?'
Each of these routes to Potential Anxiety may be minor, but their sum total is sufficient that I can't make my brain go in that direction. That is, like bricks adding up to make a wall, these sources of potential anxiety present what I am now calling an Invisible Wall.
Thus I can't begin to approach the idea of getting a job, 'because there is an Invisible Wall in the way'. The collection of those Invisible Walls gives rise to my Invisible Maze. That Invisible Maze is thus my term for a big complex set of constraints that I live within, which others can't see.
Indeed I can't see them either, only infer them from their effects. And even then it takes time to develop the awareness to pick them out.
Some say it makes sense; others say it needs to be simpler. The only way to make it simpler is to remove the explanation of the mechanism in terms of Potential Anxiety entirely and just say "I can't get a job because there's an Invisible Wall in the way". That, most likely, would turn into "John is hallucinating invisible walls". Just calling it "Anxiety" doesn't convey the multidimensional-magical-maze-like structure of the collection of pressures that Potential Anxiety imposes on me.
Some things can only be made so simple. I don't know how I could make the above explanation any simpler.
