Yes I do, but we must be aware of their limitations and create laws or regulations that curb their interests so that they are doing what is best for society, not themselves or their peers. "What is good for society" is a tricky and subjective term, and could apply for anything, but in this context I use it to describe basic Humanitarian rights and other freedoms of that nature. They must also adhere to what is agreed-upon "truth" - a fundamental concept of reality that no-one can disagree with.
The reason why I think there should be "authorities" and "experts" on certain things (like science), is because the modern human being cannot hope to learn and be efficiently literate in all the modern advances and nuances of fields like STEM, or politics. We can certainly try, but without specialized
training and thus gaining expertise
in, a certain field, we cannot pull off complicated modern tasks that our society needs. The end result of a technological civilization is to have experts on various tasks and endeavors. To make sure that these "experts" are on the right track (they are only human after all), we must refer to an authority - most often not a person or thing, but rather an fundamental theory or principle that has been proven without a doubt and which is represented by a school of thought or organization (in physics, the fundamental would be Newtonian Thermodynamics or Einsteinian Relativity, and their representation would be by other physicists).

In general I like to do my own research rather than rely on anyone else, no matter who they are.
I agree with you, but there must be some degree of trust in some
authority. Otherwise it is a slippery slope of subjective "truths". While I do not
doubt your information mining techniques, it is difficult to say for sure without relying on something already proven that the information you (or I) gather is valid. At some point, there is a bedrock idea that all of our theories rely on, and we must assume that it is true (we cannot rightly prove it, because we are not experts
on the matter of, say, General relativity). Unfettered "research" and "questioning" established authority (without much consideration for overall goals or system of origins) is how we got Flat-Earthers (mixed in with a healthy dose of ignorance and religious ideals).
