I have a mischievous thought this morning.
What might be High Functioning and Low Functioning Neurotypicality.
Would we base it on something like an IQ test, or would it be more useful to measure it by how well people can manage their neurotically traits.
For example, in the area of Delusions of Mind (a feature of people on the neurotypical spectrum which involves and inability to see what is actually there and a compulsion to ascribe metal states to objects, other people and so forth), would "High Functioning" be a person with Neurotypucality who is aware of the tendency and takes care to avoid getting into Drama about other people and situations, as opposed to Low Functioning where the person with neurotypicality becomes trapped in always immagining motives for other people's actions, fails to understand communication properly because they think the words have every possible meaning other than what the words mean.
And more compassionately, is there anything which can be done to help the low functioning NT people to have happier and less drama in their lives

First, neurotypical is not a diagnosis for a disorder. It is simply a statistical reference to typical behavior. You cannot have variation in a mean. Disorders are the variation from that mean. A low-functioning NT cannot exist as it is an oxymoron.
