The psychology of Yanni vs Laural: why do people here different things? Well, it all boils down to that our brains perceive things differently … input through the senses are processed and transformed according to the programming in our brains … we all don’t have the same programming.
… That means reality to a certain extent, is subjective!
From the article below:
“Plenty of things could be influencing your interpretation of yanny/laurel, including your dialect and whether you listened to the recording over a speaker or headphones. People have a tendency to try to match the sounds they hear onto real words that they’ve heard before, like laurel. But reading yanny first, since it appears on the left side of the poll, could have primed listeners to hear it over laurel.”
