People are voyeurs. If you put an open door on the left and blank wall on right, the majority of people will walk by and look left. The wall is already known so it’s not worth looking at. Those that continue staring ahead will remain curious about what they left behind, undiscovered.
The inclination to know is natural. Ignorance drives discovery. Where there’s cloudiness, our brain fabricates the other half just so we feel more certain.
No wonder people love social media. You can peek into someone else’s life without even revealing your presence. You may even think you know someone without ever meeting them.
Humans spy on each other, filling in gaps of mystery. Social media leaves the door wide open.
