This doesn't make studies or statistical evidence true. Just more reliable than anecdotal evidence. Humans who will lie about their observations will also produce flawed studies. Again the former (anecdotal) is unverifiable, but I can check the latter (statistical) independently.
One other point I forgot to make: It is expensive to verify a long statistical study. Not only does it require extensive knowledge of statistics, but you may actually need to reproduce much of the work. The only people who can afford to pay for such verification work may not be the same people that I would trust. Anecdotal evidence is inexpensive to collect. In many circumstances the cost benefit analysis favors it. Red Rackham
