Reality is, fundamentally, a function of agreement about perception.

There is a threshold of material reality. Disagree with buildings or gravity and you can put your survival at risk.

There are a LOT of propositions which have fewer subscribers than material reality constructs have. Any proposition having to do with consequences, for example, or future events can be considered   risky in proportion to the degree it tries to extrapolate variables. Weathermen run into this all the time.

But in terms of material reality, demonstration to others with experience or measurement is pretty much the gold standard of evidence.

When you start penetrating the Wonderland of human psychology, or spirituality, while it is still true that agreement is a core index of reality, the territory gets nebulous, volatile, not to say miasmic, riddled with opinions, and colored strongly by the individual creatuve will. So common denominators and demonstrable phenomena are harder to come by.

Most psychologists who have spent any time counseling will have their own ideas about common denominators, but it is still pretty much a jungle out there, a metaphor augmented by the myriad of jungly superstitions and witchdoctors involved.
