My father is a super stubborn Dutch guy. Needs to see proof of something 10 times before he changes a long held believe.

Long time ago something came up like this in the Netherlands. Some massive, unexplained increase in disability.

I asked how could this ever be possible?

He asked: "Are any of the disabilities that show a massive increase not objectively measurable but still eligible for subsidies?

At the time I thought it was such a backwards way of thinking but over the years I can't shake this sentence.
