I think cryptography and bitcoin offer a good start to fixing some of what you've described. With so many voices, not all motivated to properly inform, the truth becomes harder and harder to see. A bitcoin standard is a good start to establishing truth in finance and takes away the power to influence and coerce using the money printer. Truth in finance could go a long way to dispelling the insincerity and manipulation we find today in the current system.

Cryptography can also help us get to the truth through zero knowledge proofs, open time stamps, sovereign identity, and decentralized communication. There are many experiments taking place to leverage this tech to create a matrix of truth. It's a race though, as misinformation, deep fakes, and opaque AI are all over our feeds. We need to formalize our information validation so that pieces of information can be assembled into the stories that influence public opinion. Cryptography can help with this, but it needs to be integrated into our social systems as soon as we can.

Personally, I've tried to evaluate how I consume inform and how I arrive at my opinions. Of real value in that regard is the concept of epistemology and the which epistemological philosophy you subscribe to. For me it's Critical Rationalism. See the work of Karl Popper and David Deutsch.

If people used the tools and thought about their approach to knowledge, we could build a more trusting world because more of us would arrive at the truth, and faster.
