IQ is mainly heritable - your range of possible IQs is genetic, and then a few environmental factors can tinker around the edges. Severe malnutrition and neglect will lower it a bit, a decent upbringing will push it towards the higher end of your possible range and you can coach it up a few points. Barring something like a lack of oxygen at birth, or a severe accident, or severe neglect (feral child level) you’re born with a potential range that’s set. You can up or down it a bit, but not much.
