Logic 10 - The value of a datum is established by the amount of alignment (relationship) it imparts to other data.
How many times in history has a nation been losing a war when low and behold a high up commander is found to be in the pay of the enemy? Suddenly a thousand seemingly incomprehensible occurrences - lost battles, spies captured by the enemy, etc. - are explained. Suddenly alignment is given to all that data.
Another example is the idea that psychiatrists are really trying to help people recover. If we attempt to align other data in the field around that theory then we have trouble. Example: Electro-convulsive therapy (ECT) causes brain damage and most patients die after a few years. Example: mind-altering stimulant drugs such as Ritalin have been shown to cause brain shrinkage after prolonged use and studies have shown that over 90% of children taking Ritalin move on to street drugs. Example: Two side-effects of drugs such as Prozac, Zoloft and Paxil are psychosis and suicide and thousands of apparently pointless acts of murder followed by suicide have been perpetrated by people on these drugs.
Now lets assume the datum "psychiatrists are in it for the money" is true. Suddenly we see these other data come into alignment. ECT is a big money maker - easy to administer and it can be billed against insurance. When retirees hit 65 their medicare coverage increases and the amount of ECT they are given vastly increases. If a psychiatrist can keep a patient on his list and see them regularly, even though all he does is prescribe more drugs, then he can continue to bill their insurance and continue to get kick-backs in the form of expense paid trips to luxury resorts (for seminars of course) from drug companies.
