Real name policy.
A difference between Wikipedia and Citizendium is the real-name policy: Wikipedia allows people to use pseudonyms, while Citizendium requires people to use their real names and even write a short bio of themselves.
One of the reasons for the usage of real names is less vandalism. Under ideal circumstances, it would work, but in our world, it won’t, because it’s not enforceable: it’s hard to check whether a name is real. One could ask for a scanned ID, but it’s not hard to photoshop a Botswanian driving license, which would look real for a person who is not aware of how that looks like. Of course, Citizendia could also ask for a picture of you holding that ID, but this sounds too much like what the Nigerian scam-baiters would ask from the poor Nigerian scammers. The only variant which is 100% sure is having to collaborate with all the governments, which is impossible.
People say that[citation needed] for each expert, there’s another equal, but opposite, expert. So, Citizendia won’t be short of disputes, but will they be more academic and diplomatic in trying to solve their disputes? Time will tell, but in the meantime, on WikiEN-l, Stan Shebs argues that:
great knowledge tends to breed arrogance, making conflict more likely, not less so. CZ adds real names and attributions to the mix, raising the stakes even further by introducing the possibility of effect on one’s careers. The organizer would need the superior political skills of an Ivy League dean to make it all work, but Larry’s forum postings don’t evidence much improvement at diplomacy since the times he was angering editors on WP.
