A group of researchers studied why social media feeds often display exciting or unusual events instead of ordinary life. They say people are naturally attracted to excitement, and this attraction changes what appears in feeds. The researchers call this idea "rareness bias diffusion" and explain it as rare posts spreading widely because people notice and share them.
The team used experiments with fictional scenarios and a computer simulation to see how rare content moves between users. They found that rare posts can seem common when people see them often, and then more people share similar content.
The researchers say that platforms and ordinary human choices together create a skewed view, and users should remember feeds are a selection of highlights.
