If it were completely unreliable you would never be accurate even when reporting your own opinions, except perhaps by chance.
I didn’t say it was completely unreliable. I said it was completely useless.
As the saying goes, a stopped clock is right twice a day, while a working clock is unlikely to be accurate within the limits of measurement. However, the stopped clock is extraordinarily reliable—reliably useless, because it really tells us nothing at all about what time it is. The working clock may not either, but it could at least potentially be a useful guide.
