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.

Unfortunately for many Americans the antics of your favorite sitcom characters does not have much value and (don't tell them this) the evening news is also pretty low on the value scale. If you doubt it then next time you watch the news figure out how much assistance or inhibition to survival what you are being fed actually has. Perhaps all you'll come up with is that watching the news brings you down - that's inhibiting to survival.
