Information asymmetry has always been a thing, wars have been though over this.

But I think that in our age, information asymmetry is particularly low, at least in western countries. Each one of us has access to a tremendous amount of data, sure the powerful have access to more, but I have a feeling that the relative difference is shrinking.

I will always remember when a police investigator was interviewed, the context was a controversy about police files. The investigator said: "police files? not very useful, when we want to investigate someone, we browse Facebook". It means that the police doesn't have much as much of an information advantage compared to you and me.

Journalism, world events, etc... Most of the times, we have all sorts of first hand reports, photos, videos, news sources from enemy countries, etc... Not all of them reliable, and factchecking enough to see through that mess takes work, but it is possible in a way that wasn't before. A lot is available on open data platforms, plus all the shady stuff like Wikileaks, darknets, etc... that are not that hard to access either.

Should you want to, you can be your own Palantir, because most of what Palantir does is standard data analysis that can be done with open source tools, and most of the data sources are public, private data is just the cherry on top.

Of course it takes work, but it is possible with limited resources, mostly a computer, an internet connection, and time. No need to travel around the world to meet contacts and get access to paper archives.
