I'm about to set up a discussion group of my own--focused on antimonopoly policy and its social/economic effects in the world's 200 countries--and thus have a keen interest in the following question: How does one go at building a discussion list that's capable of making the largest possible contribution (to the public interest) in its field? I'm a member of--and regularly contribute to--quite a few groups. Their rules differ widely. Some are tightly monitored, others are essentially free-for-alls, stills others fall in-between. As an empiricist, my principal question is, which works best? The 'best' list in a given area is of course the one that attracts the best people --and succeeds in persuading them to contribute to the discussion their best efforts. If the most knowledgeable people are made to feel uncomfortable or otherwise unwelcome, they'll naturally vote with their feet--go away--or remain silent, denying the group the benefit of their facts and insights. Gresham's law: The bad drives out the good. Distinguished people in their fields put a high premium on courtesy, civility, graciousness. I've run across one model that especially impresses me. Its rules, first, simply ban name-calling, i.e., attacks on another member's intelligence, education, mental health, character, and the like. Secondly, though, this model includes a remedy that strikes me as eminently sensible: An e-mail address is provided for the lodging of complaints. Any member can point to a discourtesy. The offender is then invited to offer, onlist, an apology that has already been accepted by the offended member. If the name-caller declines, he is removed from the list. On the free-for-all lists, I know the names of the ideologues and either 'trash' their posts (unread) or automatically transfer them to my 'loonie' file--one that I review every fortnight or so for entertainment, looking for thigh-slappers, side- splitters, and the like. While the name-calling loonies have no just claim to the attention of a serious list's knowledgeable members, they nonetheless have rights--particularly the right to set up and protect lists of their own. Suppose, for example, that a competent astronomer should somehow wander onto a list owned and maintained by, say, the 'Flat Earth Society.' Does this scientist have a right to disturb these good people, to persistently attack their unconventional beliefs in their own forum, to embarrass them before their peers with his opposing evidence? In my view, he has no such right. He might sensibly ask them whether they've considered a few elementary factors but, once they've made it clear that they don't want to be disturbed in their error, the gracious thing to do is bid the group bon voyage and leave it in peace. This list has a couple of loonies--fugitives from a list of their own, one I courteously left some months ago to its own economc follies--who are apparently spoiling for a fight with me. If they do it again here, they won't like my response. Too bad TOES has no effective ban on name-calling.
