No, an IQ of 97 is not considered dumb; it falls squarely in the average range (90-109), indicating typical cognitive abilities, though some tests might place it slightly below the exact midpoint of 100. An IQ score of 97 means you performed better than 42% of people, and due to the test's margin of error, your score could be anywhere from the high 80s to the mid-100s, still within normal intelligence.
Some mental skills are sharpest at different ages, with many not peaking until age 40 or later. Short-term memory is strongest at age 25, stays steady until 35, and then starts to decline.
