Is it possible to model the rate at which human knowledge is increasing or decreasing? Given that: A) claims about reality are a lemon market, and it's often expensive or impossible to evaluate the truth behind purported facts. B) false claims undermine the value of true claims by decreasing trust in them, and by causing people to stop believing things that are true so as to realign their worldview to be logically consistent with misinformation. It stands to reason that if the percentage of true claims made in papers is less than X, the sum of human knowledge is actually decreasing even if good papers are still being published.
