How Can You Tell The Difference Between INFJs vs ISFJs

I want to discuss some difference between INFJs vs ISFJs.
But let us first understand this personality types.

Who is an INFJ?

INFJ is an abbreviation used in the publications of the Myers-Briggs.
Someone who has the following qualities:
~ Introverted ~ Intuition ~ Feeling ~ Judging.

They make 1% - 2% of the world population.
INFJs ARE THE MBTI MASCOT FOR EMPATHY, LOVE, & PROTECTION OF HUMAN BEINGS :).

Who is an ISFJ?

Someone who has the following qualities:
~ Introverted ~ Sensing ~ Feeling ~Judging.
ISFJs are characterized above all by their desire to serve others,
their "need to be needed." In extreme cases, this need is so strong
that standard give-and-take relationships are deeply unsatisfying to
them; however, most ISFJs find more than enough with which to occupy
themselves within the framework of a normal life.

How can you tell the difference between INFJs vs ISFJs?

* INFJs are considered the most logical Feeling type.
* SJs are the majority.
* ISFJs (and ISTJs) are memory types. They ACQUIRE knowledge through
experience and they take time before new data becomes part of their
system.
* INFJs are insight types.
* ISFJs are close minded and they don't question the rules. INFJs are
mystical, open minded and they have trust problems. INFJs believe in
what they think is correct, ISFJs - what was said to them. Intuition
vs Sensing, I think the superiority is obvious in this case, ISFJs and
generally sensors can be pretty dumb sometimes.

speaking of intelligence is like a myth.
