I'm getting to the point where I can pick up a book and form an opinion of the author's sociotype after reading a few pages.

Started Time Salvager, by Wesley Chu, who is ILI as hell. His Starship captain is SEE and the novel's protagonist is SLE, the ILI's semi-dual. Chu seems to have a poor opinion of SEEs, which is not unusual for ILIs.

It's always fun to see how other types are seen from one type's perspective.

Write what you know, I guess.

Day of the Triffids author, John Wyndham, is SEI.

The Demolished Man author, Alfred Bester, is EIE.

The Dying Earth author, Jack Vance, is ESE.
