Secretive

One of the most effective weapons of exclusion used by insiders against outsiders and strangers is to keep them in the dark as to the current talk, interests and plans central to insider business. Outsiders really do not know what insiders think or are up to, and that isjust how insiders want to keep it. It is easier to attack outsiders if they are caught totally unaware of how and when they will be ambushed. Communal insiders are very proficient at keeping communal outsiders in the dark.
