Let me rephrase your empirical observation in probabilistic terms. If the a random sample of data scientists from startups had the same distribution of mathematicians and CS people than a ramdom sample of data scientists from banking then we could compare empirically whether confidence intervals are equally useful in both industries.

Given that historically regulators figured out that when playing with other people's assets you need to assess your confidence, the volatility of the outcomes in non banking industries that lack such oversight can be greatly attributed to people DunningKrugering after a couple of Andrew NG's courses.

That is my claim and based on my experience working in projects accross many industries accross many countries.
