I agree with provisional trust in whatever technology in a field makes my car run better. I do not trust the technocrats about policy matters, and I do not trust scientists' prevailing views about the cosmos. I do not have to have any view about the cosmos, in order to live my life. I like to look at the stars. I need to know enough not to look at the sun straighton. I do not need to know whether Big Bang theory is true. I do not see why anyone has a need to know it, except for compelling curiosity and egomania, in whatever combination!<quoted text>
I agree except I would add that you simply cannot research everything. If I don't know much about a particular field and I can't research it very much I will grant provisional trust in whatever ideas in the field are dominant. Subject to change with further understanding.
I know little about engine repair. I'm content letting my mechanic handle it. He has not violated the trust yet.
on policy matters, some of the experts may be bought out, and some may be out of date. I can use my own alternative to expertise, which is risk assessment, to question views that have consequences in the real world. If we do not know enough, and do thus and so, will it be more of a risk, or less of one, than if we do something different. That is my approach on global warming (man-influenced), chemical and biological and nuclear development and use and disposal, sustainable energy vs fossil fuels - and similar issues. I do not trust scientists paid by tobacco companies or Koch brothers.
