"Type doesn't change, you'll always be one type". Oh, I had no idea type was genetic, thank you for the valuable lack of insight into the situation!
This notion contradicts what Carl Jung physically said in a real interview. I understand reading is hard and not everyone has read Jung in-depth. But this is a one minute clip, and I assure you that this should be enough to disprove this silly reply.

"Well you see, the type is nothing static. It changes in the course of life" -Carl Jung
The claim that type never changes is backed up by nothing. Not one shred of theory or logic. Not even Myers or Briggs claimed this. Enough with this generic, silly response to whether type can change or not.
