How easy is it for one's personality to change? Is there a certain age you reach where your ways remain intact, or are they always subject to change? I'm keeping in mind all the biological and environmental factors that have a hand in shaping a personality. And if it's not that easy, how long does it take?
Some people I've tried introducing the Personality Inventory to felt that the test didn't ask thorough questions (which is kinda BS to me) or that it was just an exam you take to change your habits and turn into another personality type if you wanted. No explanations I gave made it clear to them. I dunno what's so hard about finding out some details about yourself, though I know it's not 100% accurate. If you don't have as much skepticism as you have humility to a new concept...what's the point of judging something?
All I know is that ISTP pegs me so well that the test has got to be good for something. Sorry, everyone. I'm venting while I ask questions.
