The explorer mindset is how scientists discovered penicillin, x-rays, and vulcanized rubber. Science isn't as cut and dry as the scientific method suggests.

I'd say to the extent that this behavior contributes to the reproducibility crisis, it has more to do with not backing that exploration with rigorous experimentation.

But more to the point, I'd argue that the lack of funding and publish-or-perish atmosphere has more to do with it. Academics don't necessarily publish because the results are noteworthy, but because they have to, regardless of the robustness of their methodology.
