An anonymous reader writes "Our eyes can be deceived, no doubt about it, but, what do we do when "data" does not fit known patterns? When does the observed turn into fact? I am sure that Ohm did enough readings on voltages and currents to say the observed turned to fact: E=IR. But, some things are not as clear as reading a meter. What do we do then? Is the observer always declared wrong, or at some point do we change the "observed" to "fact?"
Here is a story about "officials" — (as in doctors, nurses, police) who say they saw a 9 year old boy walk backwards up a wall. Do we disbelive the observers or do we somehow after enough "viewings of such events" say that it is possible to walk up a wall or be demon possessed?
