I have read from a number sources that age has a considerable impact on your personality. The theory is that your dominant functions remain strong and frequent, however your weaker functions will develop over time. For example, an ESFp would develop their and over time and an ENTj would develop their and . Supposedly you develop your 3rd and 4th functions in MBTI and your dual seeking functions concerning socionics. From your observations of your own maturity or others, has this proved true? Is it correct that the functions that develop over time are the ones mentioned or your 3rd and 4th socionics functions? Is it possible that the functions develop based on the environment that requests them or rewards them the most. For example, if you reside in a society where is praised, could that mean that it would pressure many to develop it?
Is this source accurate or should it be judged false since it is based on MBTI?
