Personal verification is just that, personal.
To me this suggests that verification can be subjective and true to the person while misunderstood by others. Now, this leads me to think about superstition. Webster says it is the belief in some, practice, or rite held in spite of evidence to the contrary, resulting from ignorance of the laws of nature or from faith in magic or chance. To be quite honest, I'm not even sure why I do it. My point is, the word superstition has a negative connotation to it.
