A sample of his misleading analysis:
>, this framework rests on the unspoken assumption that introverts and extroverts remain constant in their identities. [...] What if that weren’t true? What if we could deliberately act more one way other the other?
>That is: am I promoting extraversion simply because I’m an extravert? The answer is: I am a little bit of both. [...] I think we’re all a bit of both.
No, introversion is not how one voluntarily acts in solitude for a little while and if that same person is later eating lunch with friends, he does not become an extrovert.
And no, you can't be "a little bit of both".
The way I like to explain introversion vs extroversion is it's an underlying personality trait that doesn't change such as being left-handed or right-handed. When we say we're "right-handed", that "right-handedness" trait doesn't go away just because we play the low bass notes on the piano with the left hand, or flick the turn signal levers of the car steering with our left hand. Just because right-handed people use their left hands some of the time for many tasks doesn't mean they are a "little bit of both". Our category of "left-handed" vs "right-handed" is specifically labeling the underlying tendency of which limb is favored and not about the cherry-picked tasks that use the opposite limb.
I've been to hundreds of parties and yes I do hang out with friends from time to time. I'm still an introvert. I'm not a little bit of both. The author's article does more harm than good in understanding what true introversion actually is.
