See here for profiles of Roosevelt, Truman and Eisenhower using the Novichkov method.
I. Judger or Perceiver?
A quick comparison to Novichkov's diagram shows Kennedy to be a Judger, not a Perceiver:
II. Feeler or Thinker?
Time to bring out the Bill Clinton and Jeff Sessions side-by-side photograph - Clinton is a Thinker, Sessions a Feeler. From the photograph, we can see that Kennedy (who Clinton resembles) is a Thinker.
This becomes even more apparent when we put Kennedy side by side with Khrushchev. According to Novichkov's method, Kennedy is a Thinker, Khrushchev a Feeler:
III. Sensor or Intuitive?
Intuitives have a peculiar way of sitting - or sprawling - on furniture. Take this photograph of Jarvis Cocker below:
Whereas Sensors tend to sit in a more conventional way - like these two men:
The below photographs pair Intuitives and Sensors: the stocky Mitt Romney and John McCain are Sensors, the gangly Paul Ryan and John Kerry are Intuitives:
JFK deports himself - when seated - like a Sensor. He also shows the tendency of Sensors towards stockiness and plumpness.
IV. Extravert or Introvert?
Extraverts appear to be content, happy and part of the external world; usually they display a great deal of tension and animation in their faces. Introverts, on the other hand, come across as the opposite: removed from the outer world and uninterested in it. They can seem doleful and sheepish (see Lyndon Johnson below) or vapid and expressionless (see Jackie Kennedy).
I type JFK as an Extravert.
V. JFK's type
Putting the letters we get j (Judger) + T (Thinker) + S (Sensor) + E (Extravert), or ESTj.
JFK was the second ESTj president to die in office.
A note on Introverted Sensing (Si). Introverted Sensors tend to look at you, but not really: their gaze doesn't focus on the object, they perceive things only in broad outline. According to Jung - and Novichkov - Introverted Sensing sees the world in shapes, contours, broad impressions and looks at the relations between objects and not the objects themselves. Novichkov describes the Introverted Sensor's gaze as bleary, unfocused and 'squinty'. That, I think, sums up JFK's gaze to a tee:
