Jeremy Donovan's study of TED talks suggests that speaker-educators are mostly:
- Inventors - people who invent things (e.g., Steve Jobs)
- Life scientists - scientists who study natural processes (e.g., brain science)
- Natural scientists - scientists who study natural laws (e.g., biologists, chemists)
- Social scientists - study individual and collective human experience (e.g., sociologists)
