The average intelligence quotient, or “IQ” as it’s widely known, is declining. It is defined by Merriam-Webster as “a number used to express the apparent relative intelligence of a person.” Not that we had to define it, but there you go.
The average IQ of the younger generations is dropping. Specifically, a study discovered that it’s dropping by about 7 points per generation, especially with guys. Something being blamed for the drop is poor nutrition. However they make and grow foods these days, paired with poor eating habits in general, isn’t delivering the nutrients needed to help develop the brain.
Another reason, and likely the main cause of the drop in IQ, is pop culture and various types of multimedia. See, back in the 60s and 70s, people would read books. We had homework that was challenging. Now, kids have video games, movies, streaming apps, all sorts of stuff. Rather than reading books, we’re staring at screens, shooting birds into buildings (virtual, of course) and running around an imaginary battlefield.
Moral of the story, put down the game controller, turn off Snapchat and Instagram, and pick up a book. It’ll help develop the brain, and, you know, reading is good, ‘n stuff. Source.
