Meeting Personalities

I finds different personality interactions during meetings fascinating. In today's meeting we have the:

1. Academic
   Primarily concerned about framework, definitions and process.
   
2. Confidently Uninformed
   Presents opinion with the confidence that because they've uttered it, it then becomes absolute data-driven fact (e.g. Anthony Scalia and the Pope).
   
3. Impatient Pragmatist
   Wants to cancel the meeting and get to work on the first draft, believes that iterative "doing" is far more productive than talking.
4. Demotivated Pessimist
   Those who've given up and are willing to ride a sinking ship as long as possible. Make occasional contributions, but gives up easily due to historical lack of progress.
   

Today, I'm #3. Who wants to define some additional meeting personalities?
