"The Scout Mindset: Why Some People See Things Clearly and Others Don't" I liked this book as well. Here's Max Born supporting the mindset.

I believe there is no philosophical high-road in science, with epistemological signposts. No, we are in a jungle and find our way by trial and error, building our road behind us as we proceed. We do not find signposts at crossroads, but our own scouts erect them, to help the rest.

- Max Born, as mentioned in Experiment and Theory in Physics (1943)

kipling's "the explorer" also glorifies (in a positive sense) this mindset https://www.kiplingsociety.co.uk/poem/poems_explorer.htm - it's literally about geographic exploration, but also about exploration of all kinds.
