> Yet, human achievement in domains such as career success tends to peak much later, typically between the ages of 55 and 60. This discrepancy may reflect the fact that, while fluid intelligence may decline with age, other dimensions improve (e.g., crystallized intelligence, emotional intelligence).
Isn't it about accumulated human capital (aka social networks) and experience more than anything else?
Yes, and that’s also why “career success” here really only means “modern era white collar career success”. In other times and other fields it can look very different.
This definitely is not true, outside of physical domains.
I chose a random domain (philosophers writing their seminal work) and found that most wrote them in their 40s. Kant wrote the critique of pure reason at 57 years old!
This is a pointless discussion though without talking about testosterone and dopamine levels. Doesn't really matter what your IQ is at 60, if your testosterone and dopamine system is that of the average old man you are not going to have the desire to write Leviathan or Critique of Pure Reason.
