Is it normal for your iq to go lower and lower over the years?
Military iq test results at 19 years old: 142-144
At 27: 132
At 33: 127
At 47: 115
I was very tired when I took the last test as I'd been awake for 30 hours which may have skewed the results, but it still seems that my iq is dropping markedly with each decade. People I work with tell me that I'm very focused and I dont make mistakes a lot, but if you look at my iq results I'm getting dumber and dumber with each passing year. Normal or not?
