Someone I know sent me a link to a 'peer-reviewed' paper 'proving' that hydroxycloroquine cut mortality rate 'in half' from the Henry Ford Health System in Detroit. However, a cursory look at the data shows a large median age discrepancy between the populations receiving treatment -- the no HCQ group was significantly younger. The vast majority of people have outsourced their opinions to 'trusted sources'. And a sizable fraction suffer from massive confirmation bias.
