Saying they are experts are like telling you who is sexy or not. It's subjective. Some people really consider Marx or Friedman as the truth for instance. Digging deeper in the weeds we can make claims either way. Experts are often self appointed as well. If I was to declare myself an expert in an obscure area you don't understand by making wild claims that sound plausible it would be hard to say I wasn't and if some peers accepted it it would be even harder to deny it. An expert shouldn't be self appointed and if nobody trustworthy calls someone an expert they shouldn't be considered one too. If you consider someone an expert on your own by their knowledge it's different.
