Many people seem to unrealistically demand scientific recommendations to be "guarantees." However, scientific conclusions are very precisely made best guesses, built on humanity's knowledge.

It's good that the supply chain of science is traceable, but it doesn't guarantee truth by any means. Their are many non-scientific human endeavors that have traceability, take software development for instance.

I think the distrust comes from many fields having fairly obvious political trends, in particular social sciences. Another source of distrust is overextrapolation of science by authorities. For instance, science might say that certain drugs are harmful if abused, and politicians may use that to claim the war on drugs is based on science, which obviously is not true. Lastly, some fields struggle producing consistent and falsifiable results, such as economics and psychology.

58% (quite high, higher than a lot of biology related field) are positive replications.

But! some of those use the same datasets, with different time bases, and most are narrow replication of high impact studies.

Also, economics now is not a singular field, and I'd bet gp was talking about macroeconomics. You could be more charitable.
