In the absence of data yes, but intuition and judgement are just heuristics; they suffer strongly from personal biases and are not necessarily representative of reality.

It also requires judgment and critical thinking to decide things like:

a) is this data accurate

b) is this data complete

c) is this data relevant

etc.

So even the act of selecting data is subject to bias, good judgment.

		You make it sound like you’re just shifting the problem elsewhere, when this isn’t the case. It’s not wholly subjective. Some of the processes you can use to understand your data are mathematically proven. Many others are well-tested. In any case the idea is to try to minimise your biases and check whether your assumptions are valid so that you can make better, more reliable, more informed decisions. It doesn’t have to be a perfect system to be better. You might not want to, of course.
