The world in the 21st century is the same it used to be. It smells about the same, sound pollution is pretty stable. But the spill of information and distraction that comes to our vision has grown ceaselessly for two decades, with no sign of slowing down.

Our brains tend to lean heavily on the visual and prioritize sight over the other four senses.

• Information overload was a term coined in the mid-1960s by Bertram Gross, a social scientist.
• In 1970, writer Alvin Toffler popularized the idea of information overload as part of a set of predictions about eventual dependence on technology.
• Another set of academics wrote that information overload occurs when the amount of input exceeds its processing capacity.
• A 2011 study found that on a typical day, Americans were taking in five times as much information as they had done 15 years earlier.
• A 2019 study identified that our attention span is shrinking, probably because of digital overload.
