This podcast discussion summarizes a study using eye-tracking to examine how people process online information. The research reveals position bias, where information presented first receives disproportionate attention. Pupil dilation indicated increased cognitive effort when encountering information contradicting personal beliefs or presenting incorrect evidence, especially when aligning with pre-existing biases. Interestingly, belief changes didn't significantly impact cognitive load. The study highlights how our brains prioritize information confirming existing beliefs, even if inaccurate, emphasizing the need for critical thinking and awareness of cognitive biases.
