You think there is any solution to this? We are all ignorant. You can spend your entire life dedicated to a tiny subset of a field of hard science and still only end up as an expert by the end of your life in that particular sub field, not the entire discipline.
You think even the academic EXPERTS have an accurate grasp of complex systems like social interaction, politics, psychology, economics, etc? These "sciences" are still in their infancy and most people studying this stuff rely on the many compounding presuppositions and cultural norms to form their concept of truth. How many of these social studies written, curated and published by EXPERTS can even be replicated?
How the hell do you expect the average person to have a grape of what's true for economics, philosophy, politics, psychology, etc. All simultaneously? How the fuck do you think people can do this when society becomes exponentionally more complex due to increasing rates of change and population?
Nobody has any fucking idea what's true outside of objective sciences. Humanity has an ignorance problem but that does not necessitate a solution. The problem is eternal.
