Sure it would. In fact, I try to only believe things for which I have clear indications.....
Is that belief, or knowledge?
...For example, I refuel my car when the fuel gauge provides me with a clear indication that I'm about to run out, precisely because I believe that further driving will leave me stranded at the side of the road...
Folks like you need a fuel gauge. Sometimes they still run out of gas.
Did you know that lots of heavy equipment don't have fuel gauges? The operator just knows that the equipment won't run without fuel, and knows damned well he'd better fuel up at the beginning of the shift.
But, you're right. Not everybody can do that.
Some folks need a gauge.
They can't be operators.
