There is no such thing as absolute reality. Each of us has our own version of what we think of as reality. If we know that about ourselves, we're OK. But if we think that our reality is everyone's reality– or that we think we know others reality, we are mistaken.
A 7 year-old girl's reality in an affluent California suburb couldn't be close to that of a 73 year-old farmer in war-torn Yemen. We are all in our separate bubbles (sketch) with our own knowledge and experiences shielded from the outside world and things we don't know and in most cases, can't imagine.
Our own personal reality is a result of our experiences– those we know and things we've seen, heard, felt, tasted, smelled and believe to be true.
Since we have different realities, laws, customs, peer pressure, morals, ethics and a desire to belong influence us to seek and function within an accepted common reality. This concept of an accepted common reality works well for most as long as we all have the same understanding of the influencing forces. But, again we are different and don't have this same understanding. So as a result, there are levels of reality. What we want to believe is on the top level. Below that is what we suspect is happening that doesn't quite sit well with us. Under that are yet other levels, some of which we don't even want to know about. Yet they effect us.
The true test of a reality is when it competes fairly and directly with other realities in a given domain with commonly understood rules and objectives.This comparison is now possible between that 7 year-old Californian and the farmer from Yemen when playing BUX. The results of these encounters could be exciting and revealing benefiting all.
Insights, solutions and breakthroughs commonly result from diverse reality sharing. Same/similar-reality sharing, inbreeding, rarely results in breakthroughs.
