Evaluation of Data - Scientology Logics 7 through 12
Logics 7 through 12 are all about evaluating data so let's see them in action.
Mom observes that the apple pie is missing from the stove top and that the empty pie dish is lying by the dog's bowl.
She puts forth the hypothesis that the dog ate the apple pie. She attempts to apply Logic 10 to this: "The value of a datum is established by the amount of alignment (relationship) it imparts to other data." It doesn't fit too well because another datum is: between the edge of the stove top and the pie was another pan which was not displaced. The dog hypothesis doesn't align with that because the dog would have knocked the other pan out of the way.
She now applies Logic 8 "A datum can be evaluated only by a datum of comparable magnitude." A datum of comparable magnitude would be who has the capability to lift the pie dish from the stove and put it by the dog's bowl. Possibilities: husband or son.
Now she applies the 2nd corollary of Logic 7 "Truth is relative to environments, experience and truth." From her experience if husband had wanted to eat some of the pie he would have simply eaten it.
This leaves her with the hypothesis that son ate the pie and tried to frame the dog. She goes to son's room and finds crumbs under the bed. To gather more data she finds son and asks him if he'd like a sandwich because from her experience (2nd corollary of Logic 7) she knows that he is usually hungry at this time of day. He says no thanks, he's not hungry. She applies Logic 10 again and sees that the datum of the crumbs and the not being hungry align with the "son did it" hypothesis.
She asks him if he ate the pie. He denies it. She notes that he can't meet her eye-to-eye and, again, from experience knows that this is usually a sign of son not telling the truth.
Now she has to decide what to do. She uses Logic 11: "The value of a datum or field of data can be established by its degree of assistance in survival or its inhibition to survival" and Logic 7 "Gradient scales are necessary to the evaluation of problems and their data." She evaluates that this is extremely serious and that son should be grounded for the rest of his life. Then she recalls Logic 12: "The value of a datum or a field of data is modified by the viewpoint of the observer" and realizes that her viewpoint is affecting her decision. She then re-evaluates and decides that the pie eating was bad, but not terrible, the lying was worse and the framing of poor Rover was the worst. On a scale of offences from 1 (minor) to 10 (severe) she decides that son's actions end up at about 7 and that his future survival (Logic 11) is endangered by him having the viewpoint that it's okay to do such things.
She assigns him menial house cleaning and trash disposal duties for a week and requires that he study "The Way to Happiness" so that he understands for himself why lying is not a good idea and what the consequences of unethical behavior are, not only to other but to him personally.
So there you have a very down-to-earth (and hopefully humorous) example of how to evaluate data and come up with logical solutions using Logics 7 through 12.
