interesting General intelligence probably peaks at age 30. Working memory, perceptual speed, visual-spatial thinking and "fluid thinking" (a person's ability to adapt to new situations, think logically and solve unfamiliar problems on the fly without relying on previous experience, patterns or education) reach their peak relatively early in life. Only what is called "consolidated knowledge" (closer to the concept of "life experience") improves significantly after 30 years, reaching a peak of 68 years. (But there are differences between countries. IQ peaked at the age of 29-34 in the American study and at 38 in the Swedish study) In fact, to be successful a person needs to realize himself until the age of 30-35, and then "ride" on a kind of allowance from the profession and the right place of residence, horizontal connections, a good family and accumulated experience. Also, such data refutes the now fashionable practices of "social engineers" that a person can supposedly learn something new successfully throughout his life, up to old age. that almost a 50-year-old driver or nurse can become successful IT specialists and even scientists. No, over the years, retraining and acquiring new knowledge will be more and more difficult and it is more likely that this is a way of survival (not dying of hunger while looking for a new job), and not success. Moreover, we see that "consolidated knowledge" usually refers to only one professional field.
