What Introversion Actually Is
Introversion, as psychologist Carl Jung originally described and as contemporary personality research consistently supports, is a preference for processing experience internally rather than externally.
An introvert gains energy from time alone and loses energy in prolonged social interaction. She does her best thinking in quiet. She typically prefers depth of interaction over breadth. She finds large social gatherings tiring in a way that has nothing to do with anxiety — simply the energy requirement of sustained external engagement.
What introversion is not: Shyness. Fear of social situations. Dislike of people. The experience of feeling that something is wrong with you in social contexts.
An introvert who is not also socially anxious can walk into a room full of people and be genuinely, enjoyably present — while also looking forward to going home.
What Social Anxiety Actually Is
Social anxiety is a fear-based response to social evaluation — the anticipatory anxiety before social situations, the self-monitoring and self-criticism during them, and the retrospective rumination ("what did I say?", "how did I come across?") after them.
Social anxiety is not a preference or a personality trait. It is an anxiety disorder — on a spectrum from mild to severe — that causes genuine distress and impairment. A person with social anxiety is not simply "more of an introvert." She is experiencing fear.
What social anxiety is not: A personality quirk. A version of being quietly thoughtful. Simply "not being a people person."
A person with social anxiety may want to connect deeply with others — may genuinely enjoy people — while experiencing significant distress around social situations.
The Key Distinction
Introversion produces preference. An introvert prefers quiet to noise, depth to breadth, internal processing to external processing. She makes choices accordingly, and those choices feel like genuine preferences rather than the avoidance of something threatening.
Social anxiety produces avoidance. A person with social anxiety avoids social situations because they produce fear, not because she prefers quieter contexts. The avoidance brings temporary relief — and maintenance of the anxiety in the long term, because avoidance prevents the disconfirming experiences that would reduce it.
The test: when you avoid a social situation, does it feel like choosing what you prefer? Or does it feel like escaping something threatening?

Why the Distinction Matters
If you are genuinely introverted, the most helpful response to social fatigue is honouring your energy needs — building in adequate alone time, choosing depth over breadth in your social life, and releasing the social anxiety about being someone who needs more quiet than others do.
If you are socially anxious, the most helpful response is very different — typically some combination of cognitive behavioural approaches, exposure to feared situations, and professional support. Treating social anxiety as introversion — simply "honouring your nature" — maintains the anxiety by continuing the avoidance.
Many people are both introverted and socially anxious. The combination is common. Distinguishing which experience is present at any given moment — the preference or the fear — is what determines which response is most helpful.
