Except for maybe managing their own emotions, I think that many people with 'SA' are exceptionally emotionally attuned, readily detecting micro-gestures and their emotional implications. They may
habitually respond with irrational levels of anxiety, and still recognize the irrationality on an intellectual level.
Much the same way that you can look at this graphic and, through thought, accurately compare the men's heights, but can never shake the
feeling that there's something amiss.
Even so, I agree that emotional intelligence probably plays a significant role in many cases of SA.
