Although the haphazard methodology and tiny sample size don't allow for any authoritative conclusions, the higher extroversion scores for avatars were fairly significant and consistent as visualized by the chart below.
If real research were done through this modality, it would be interesting to see difference between sub-categories of participants. For instance:
- Subcultures such as Furries vs. Extropians (are there any furry Extropians?)
- Casual users vs. those who spend 20+ or 40+ hours per week
- Business users vs. personal users
- Human gender including same-sex and cross-sex avatars
