Look First, Not Last

The advantage of probabilistic systems is that they benefit from the wisdom of the crowd and as a result can scale nicely both in breadth and depth.  But because they do this by sacrificing absolute certainty on the microscale, you need to take any single result with a grain of salt.  Wikipedia should be the first source of information, not the last.  It should be a site for information exploration, not the definitive source of facts.
