People often believe that if they can construct a chain of reasoning which supports their beliefs that therefore they have demonstrated that their belief is true and informative. For example, many people reasoned out arguments which they seriously believed demonstrated that on January 1, 2000 the world would be thrown into chaos. I say their beliefs were serious because they acted on them – they stockpiled food, for example, they bought portable electric generators, and some even created fortified shelters to protect themselves from people who hadn't stockpiled food or bought generators.
As we found out, they were wrong. However, I can’t say that their conclusion was any less sound than the conclusion I and most other people drew that any disruption that might occur on January 1, 2000 would be minor. The people who drew this conclusion were sane and their reasoning from their data was sound. It was probably as sound or sounder than my own. In the end, one reason I and most other people were right and they were wrong is that we were using better data – data which were more informative. Another reason is that we were just luckier. In fact, no one fully understood all the factors one would have to assess to produce an accurate forecast of what would happen to the power grid on January 1, 2000. Furthermore, we probably weren’t aware of all the factors that would have to be considered.
If sound reasoning is based on invalid and inadequate data, it will reach invalid and inadequate conclusions. None of us is perfect – not even, as unlikely as it may seem, you or I – and we all at one time or another base logical conclusions on unsound data. And sometimes our reasoning just slips a gear, too. Even if our reasoning is perfect, none of us is omniscient, either. We can easily overlook important considerations.
That’s why the betting industry exists. If you’ve ever heard some of the explanations – often vehement ones – which horseplayers come up with to explain why the sure thing they bet in the last race ran as if he was pulling a milk wagon, you’ll know that relying too much on reason can not only cost you money but also lead you into an unjustified skepticism about the honesty and competence of one’s fellow human beings.
Obviously logic is involved in the development of information, just as facts are involved. It is not by itself informative, though. Two plus two equals four, but if the right answer is five you’re still wrong. That is why conclusions drawn from data need to be tested before they can be accepted as sound. If you think the 5-horse in the next race is going to romp, you won’t know that you’re right till the race has been run. And no matter what the weather report says, you won’t know whether it’s going to rain tomorrow or not until tomorrow arrives.
