Nonchalent participant type

Conference participants who make a display of their lack of involvement through open cynicism, nonchalance, horseplay, and other kinds of studied inappropriate behaviour.[Advantages]

A catalytic challenge to all the other members of the groups they are in; they are a reminder of the real world.

[Disadvantages]

They can distract a lot of attention in their direction which rarely has any effect on their level of involvement and can frustrate the others.
