🧠 1. Core Nature of the Trait or Condition
| Introversion | Autism (ASD) |
|---|---|
| A personality trait — part of the normal spectrum of human temperament. | A neurodevelopmental difference affecting communication, sensory processing, and social understanding. |
| Not a medical diagnosis. | Clinically diagnosable condition. |
🗣️ 2. Social Interaction Patterns
| Introversion | Autism |
|---|---|
| Prefers small groups or alone time to recharge but understands social rules and cues. | May find social rules confusing or unnatural; can struggle to interpret facial expressions, tone, or body language. |
| Often enjoys socialising with the right people or in the right setting. | May want to socialise but find it difficult or overwhelming to navigate. |
| Can “fake extroversion” temporarily without distress. | May mask social difficulties, but it usually causes exhaustion or meltdown later. |
🔊 3. Sensory Processing
| Introversion | Autism |
|---|---|
| Sensory processing is typically typical. May dislike noisy crowds because they’re draining. | Frequently experiences sensory sensitivities (to noise, light, touch, smell, texture) or sensory seeking. |
| Discomfort tends to be about overstimulation in social contexts. | Sensory overload can occur even when alone, depending on the environment. |
🧭 4. Communication Style
| Introversion | Autism |
|---|---|
| Understands and uses sarcasm, humour, tone shifts, and social niceties naturally. | May take language literally, miss implied meaning, or find small talk confusing. |
| Might prefer texting or written communication for comfort. | Might prefer direct communication because social nuance can be confusing or draining. |
🧩 5. Repetitive Patterns and Special Interests
| Introversion | Autism |
|---|---|
| No strong tendency for repetitive behaviours or intense fixations. | Often has deep, focused special interests and may engage in repetitive routines or movements (stimming). |
⏳ 6. Developmental History
| Introversion | Autism |
|---|---|
| Social understanding develops typically from childhood. | Signs usually appear in early development, even if diagnosis comes later. |
| No early language or social communication delays. | May have early differences in language development, play patterns, or social connection. |
🧘 7. Recovery After Socialising
| Introversion | Autism |
|---|---|
| Feels tired or drained after social events but can recover with rest. | Might experience meltdowns, shutdowns, or sensory overload, not just tiredness. |
| Usually doesn’t need rigid structure to function. | May need predictability, routines, and structure to feel safe and regulated. |
👉 Key takeaway:
- An introvert chooses to be alone for energy and comfort.
- An autistic person may struggle with social interaction or sensory input, not simply prefer to avoid it.
- Many autistic people can also be introverts — but not all introverts are autistic.
