On the other hand, why is it a good idea to simply accept what "experts" have to say at face value? Experts were wrong about the housing market, they were wrong about the 2-16 election, they were wrong about the iraq war.
Look at everything else the eggheads did right. For example: the modern world
I'd say there is more cause for trust than skepticism. Just because they may not agree on guns or abortion doesn't mean their opinion on everything else is wrong. Same goes the other way.
Ok, I think you and I are not arguing the same issue. I'm not disparaging the role of "experts" when it comes to advancing society, tech, our economy, etc. Outside of luddites and economic dullards, you won't find people against technology.
The issue with "experts" in the political sphere revolve around 2 huge issues.
1) social science is not a science, has extremely high causal density (an innumerable amount of variables), and you cannot perform randomized control experiments in the social sciences. So, "experts" on gun control, or welfare, or economics, or crime are much less well-equipped than their hard science counterparts in actually determining the correct route or ont.
2) The issue of personal liberty. Experts, in the framing of this particular issue, tend to think that because they have higher IQs, they have some sort of right in ordering people around and designing society as they see fit.
Society is not a petri dish. It's not a lab where one person can manipulate, restrict, add, or subtract things as his/her will. It's a collection of an innumerable amount of individuals exchanging in mutually beneficial exchanges with others, all bounded by a shared sense of morality and right/wrong.
A scientific solution to something may not have a political/societal solution. For example, overpopulation. The science says it needs to stop. How do you do that politically?
