It seems to me that even more than what you are researching, it depends upon what you think the scientific attitude is.
To me, the scientific attitude is one of eternal questioning, and eternal reliance on the evidence of experience to determine which of the candidate explanations available seems to meet all the available evidence within the uncertainties present in the experimental systems.
As such, the scientific attitude has two major foci:
1 understanding ourselves, our systems, the biases present within us, and finding effective tools to mitigate the effects of those biases; and
2 developing useful understandings of the rest of this reality within which we find ourselves.
Both seem to be potentially infinite paths.
The old Zen Buddhist saying that goes roughly like – for the master, on a path worth traveling, for every step on the path, the path grows two steps longer – is a great description of the necessary consequence of exploring any infinity, let alone an infinite nest of infinities.
And on this path, we must all start with the defaults delivered by biology and culture, and we must all be responsible for the paths we choose from that start. All such starts have many sets of simplistic heuristics that worked over some sets of times for our ancestors. That fact contains 3 major sets of risks:
1/ the risk that the simple understandings that were close enough for the past, may not be close enough for the present or future. So we must abandon all notions of Truth, and adopt probabilistic interpretations in all things.
2/ the risk that we underestimate the complexity and utility of lessons from our deep past encoded in our biology and culture, and in so doing dismantle something that has existential level value built in. A degree of humility is demanded.
3/ the risk that discovering something new that invalidates some aspect of our older systems then blinds us to other aspects of what is present.
And in doing modern science, we must be willing to question everything, and it pays to show respect when asking such questions. Both as individuals and as cultures, we are deeply complex, far more so than any individual human is capable of understanding in detail.
The science is now clear, that we never have direct access to reality. All of our perceptions are of a subconsciously generated model of reality, never of reality directly. Thus any understanding we may form is already a map of a map in a very real sense.
So there is a lot to gaining and maintaining a scientific attitude:
keeping a sense of childish wonder;
retaining uncertainty even when we are very confident;
being alert for the subconscious intuitions from our neural networks that all might not be as it seems;
being prepared to question the things that have served us best, if there is evidence that such questioning might be required;
being prepared to be a lone voice against the consensus if the evidence is that strong to us personally;
actively searching for sources of bias and uncertainty at every level of process and comprehension.
Having a scientific attitude is not necessarily a socially comfortable thing.
