It's got facts in it.
The fact that said facts contradict your anecdote is neither here nor there.
If you doubt the data, show how it's wrong.
Otherwise you're just telling stories and agreeing with yourself: which is fine, but saying "ooh he's cooked the figures because his findings contradict my anecdote" is daft in the extreme.
This is the kind of analysis that woomongers of all stripes employ.
