The blindness is to reality and nuance.

If you stare at your GPS and don’t pay attention to what’s in the real world outside your windshield until you careen off a cliff that would be “blindly” following your GPS. You had data but you didn’t sufficiently hedge against your data being incomplete.

Likewise sticking dogmatically to your metrics while ignoring nuance or the human factor is blindly following your metrics.
