Usage notes
Psychologists tend to distinguish between introversion, which defines one's inherent social preferences and exists on a spectrum of behavior with ambiversion and extraversion, from shyness and other manifestations of social anxiety or trauma. Popular use tends to lump such behaviors together and sometimes pejoratively consider them withdrawn or antisocial.
