Individuals make up any collective, whether its a shared viewpoint or a corporation. As Individuals vary, it would be short-sighted to judge a belief or system of beliefs by the actions any one individual, or small group of individuals. So I dont.
The benifits of a worldview have a cause and effect relationship with it's ideals and philosphys. An ideal of compassion has the benifit of a sense of peace. A belief in abundance can lead to wealth. This cause/effect relationship is one way I ascertain the value of a belief within a system. It is both the individual ideals and the benifits of such that attract me to a belief system.
The originator of a viewpoint usually isn't. Someone knew it before they did, and all they are is the messenger. If the originator is an individual or small group, I can only put a limited amount of value in using one to judge, as I stated above.
I incorporate many "worldviews" under one "umbrella".
I see my place in the universe, whatever I know or don't know, and that somebody else does/doesn't know.
Behavioral choices, hmmmm. The worldview I chose concerning behavior is a do unto others sort. "Harm none and do as though will" ,The Wiccan rede sums it up nicely.
It causes inner-conflict to go against one's beliefs. Its not that uncommon for a person to believe something and then act in away that isn't in accordance with that belief. Guilt is the likely to be felt in this classic inner-struggle. Perhaps it builds character or something, to learn from yourself like that? Anyway, once again I point out a cause-effect relationship between action and belief.
Supernatural...does that mean beyond nature or Nature enchanced? Ive definitly had some enchanced expiriences with nature. I believe in the inner-realm of each individual, and that angels and spirit guides are exist within and without. They told me so.
Also -ghosts, astral projection, esp, remote viewing. All Perfectly Natural if you ask me
So I think as much introspection as extraspection is important to ascertaining a world view. Being open-minded and juggling ideas for oneself and relying on logic and intutition together to judge fairly and accuratly.
