I am interested in exploring how accurate very brief descriptions by people with no experience in socionics can be.

So in the same spirit of my thread on a description by Queen Victoria, here is a very brief description of a very major figure of 20th century history, by someone who knew him very closely.

He takes everything personally -- He wants to teach others, but learns unwillingly himself -- He loves glory and is ambitious and jealous. In order to get him to accept an idea, you must act as though the idea was his. You must make everything easy for him. He readily encourages others to take bold steps but throws them overboard if they fail. Never forget that he needs praise -- he is as grateful for it as a good and clever child.
Does that suggest any particular type?
