No one sees exactly what another sees (not even the same colors). No one hears the exact same words as another hears, as their interpretation of the words differs depending on their teaching, situation, and/or life experiences. While some may fear the exact same thing (i.e. spiders), it may be for different reasons. Everyone is different. No two people have the exact same teachings, knowledge, or life experiences. This uniqueness is what allows us to have different perspectives. Even so, we can agree on things. But even in agreement we may not be seeing it the exact same way. Usually we turn a deaf ear and/or a blind eye to others, it's usually because we know we're right and they aren't. We've made up our minds and then closed them. We're all guilty of doing this at one time or another.
So at least in that one respect we are all alike. Thank you for your thoughtful reply Shuhak. Some of us are less different and some of us are more different. How big the differences are varies vastly.
When the Yanny frequency spectrum is driven low, I can hear Yanny distinctly. At all other times, I hear it as kind of a weird background counterpoint to Laurel.
The New York Times had an excellent web page when this phenomenon first emerged where you could manually adjust the frequency spectrum of each word and see under what circumstances you heard either one. But I doubt it's up anymore.
