Assuming that the most sophisticated lie detectors can yield results with a known degree of accuracy given a large enough sample, is it possible to state with any mathematical certainty whether or not a common claim is true or false, given a large enough sample of alleged witnesses. Assume that we have a clearly identified type of event, but not the same event common to all alleged witnesses.(adsbygoogle = window.adsbygoogle || []).push({});

For example, if 1000 people all claim to have seen a automobile accident at close range [described as absolute certainty] - again, not the same accident, but an accident - and if we can say that our lie detector yields results accurate to 90% in 75% of the people in any large sample, with the other 25% being completely unreliable, and if 900 of the 1000 alleged witnesses pass the lie detector test as truthful, do we have a mathematical statement of certainty as to whether or not automobile accidents happen?
