@INSTAGRAM it’s called “Uncertainty and Surprise Jointly Predict Musical Pleasure and Amydala, Hippocampus, and Auditory Cortex Activity” by Vincent KM Cheung
there is this guy on threads who only posts flowcharts and diagrams that summarise the key points of books (bookishforge) and I'm obsessed. as a visual learner, and a lover of books, this gives me enough of a taster to decide whether it's worth reading the whole book or not. probably not good for fiction books because spoilers but an absolute treat for non fiction.
