“The novel find­ing is that heart rate cor­re­la­tion be­tween sub­jects does not re­quire them to ac­tu­ally be in­ter­act­ing, or even be in the same place. They can be lis­ten­ing to sto­ries all alone at home, and their heart rate fluc­tu­a­tions will align with the story, and thus cor­re­late with other lis­ten­ers. It’s not the in­ter­ac­tion be­tween peo­ple but the story it­self that does the trick.”
