Question: Is the avrage human brain geting smarter or dafter

One way we measure intelligence is using a set of questions called an IQ test. Over time IQ tests had to be made harder with trickier questions because humans kept getting smarter! Some studies have shown that now IQ test scores seems to be dropping. It’s very hard to say if overall humans are getting smarter or dafter but we do keep creating some great technology!
