Agreed. But there is science to be paid for here and EU should pay for it now that the US has chosen to kill science and education: What percentage of a person's knowledge is true by the ASK trust algorithm in everyone's brain and used all the time. This is the equivalent to the amount of critical thinking a person does. It would be interesting if this could be correlated to societal measures. The experiments are easy to do. I do not believe there is a legit scientific literature here because ASK was developed in industry management theory (but it would be in experimental social psychology and cognitive science).
