You have these backwards. The definition I gave of introvert is the accepted/technical/actual definition. Myers Briggs use the word introversion to capture a concept that is much wider than introvert. For example it makes claims and assertions about the mechanism of "drawing and rebuilding energy" which is clearly a metaphor, not an actually measurable quantity.
Ok, I'm getting confused then... The article uses the Meyers-Briggs definitions.
I'm struggling to find the definition you're using. For example I found this:
"Introversion is not the same thing as shyness but it is
often mistaken as such by extroverts, who may find it
difficult to relate to introverted tendencies. Introverts
prefer solitary activities over social ones, whereas shy
people (who may be extroverts at heart) avoid social
encounters out of fear." [1]
Yet if I understand you correctly, there is another definition of introversion that equates introversion with shyness. Can you provide a link or expand your explanation?
