Mass anxiety is not a conspiracy theory but rather a measurable social effect. See social cooling. I didn't say there is somebody controlling or forcing the population into technoc…

The same baseline problem holds for hospitalizations as well. Nobody knows how many hospital beds were occupied in the last 10 years. Evidence points to a strong decrease in hospit…

1: This has nothing to do with excess mortality per se but rather with proper data analysis. 2-3: That's exactly what I mean but you should not measure excess mortality as absolute…

I never said it is a paradox. I never said that PA or Q is inconsistent. I said that they cannot prove their own consistency by Gödels theorem. Hence we don't know if Gödels theore…
