ID / TL;DW: young Black man explains the history of voodoo dolls: they originated in England, where Black people where prohibited from learning to read or write, to help witches keep track of what ailed their patients. Eg., person goes to witch and laments headache, they treat their headache and make a small doll (called "poppet"), trying to represent them as good as possible, stick a needle in its head and put it up a shelf. When they return next week, the witch takes their poppet and asks about their headache. If it's gone, they remove the needle, otherwise they know they have to treat a rather persistent headache.
