You can’t put this on a few. It’s the genuine desire of the American voter.
They also think they are not always correct, not always unbiased, and possibly not always honest; and the bias tends to be towards either things that benefit the urban elite, or "luxury beliefs" that have disproportionate costs on other people.
Wouldn't economics and sociology PhDs have both more room for bias in their work, and tend to have power over the economy and society?
"Experts" have a lot of sway over the public sector and legal system.
The public sector has increased to take up a huge percentage of GDP, and the legal sector has also arguably expanded a lot in power.
The perception is that a huge amount of public spending is controlled by the public service, and they tend to defer to academics if the executive keeps them in line.
The post you responded to asked about a specific aspect, namely political power, of math PhDs.
Your response was to state that surely other PhDs have bias in their work.
Are you not realizing that that's quite obviously a bad faith argument? Somebody claims that A has B and your respond that C had D, insinuating GP made connections between A and D or C and B. They didn't.
It's quite common to argue like that, but you did throw around the "bad faith" term. You need to measure your own behavior by that standard when accusing others.
