Why is it that INTJs are thought of as more analytical than INTPs, and INTPs more creative?
Because INTJs have Thinking on the outside and INTPs Intuition.
If we say being analytical is associated with Thinking, than wouldnt the type that has Thinking in the first function tend to be more analytical than the type that has thinking in the second place?
Or how about, if we say that Intuition is the salient factor concerning creativity, wouldnt this suggest that the type that has Intuition in the first place would be more creative?
The case is that we are more comfortable showing the world our extroverted functions more than introverted. So with the INTP, you will not see how analytical they really are unless you're in a close association with them. You will not see the INTJ's imagination unless the environment is appropriate. In most cases you will see the rigid Te that is particular about the way that things are done.
