Gen Z is now officially the only generation to measure lower than their predecessors in intelligence. A neuroscientist says this is because short videos and summarised texts are being increasingly relied on, but this is not how the human brain works.
Good in what sense? Consider that people do better on an IQ test if you offer to pay them more based on their performance. One might conclude that Gen Z values the IQ test than prior generations, or it could be reflective of the environment having more food swamps.
