In 2017 an entire book was written on the topic:

This is nothing new of the US:

For me, the salient turning point was the Reagan administration, which began cultivation of the attitude that government collection of routine data on weather, railroad traffic, crime, health, ... was intrinsically suspect, expensive, and partisan, rather than a public service and scientific adjunct.

I'll say this a different way: my personal opinion is that there's at least a whole book that deserves to be written on the documentable underinvestment in government measurements of national characteristics. We've trained a couple of generations--especially the most recent one--that rhetoric, rather than analysis, is the appropriate basis for policy decisions.

Skepticism, or at least reserve, in the face of expertise, can be a healthy impulse. It's simultaneously a leading slogan of the jingoistic playbook of authoritarians. Anti-intellectualism isn't a solvable problem: it's an ongoing temptation that every society needs to address in contemporary terms.
