Abstract
We present a linear formalism which makes explicit and precise the confirming effect of independent multiple observers and repeated trials on composite ratings, taking as parameters quantitative estimates of the subjective inputs discussed.
Note that the subjective probability used here is so used to study the past not predict the future and is rather limited to what has been called in artificial intelligence "certainty factors," which are arbitrary, or, more well-known, the arbitrary values ascribed to predicates in fuzzy "logic." This is clear because the scales themselves are arbitrary and of the radio-button type.
