Talk:Duggan–Schwartz theorem

From Wikipedia, the free encyclopedia

definition please

4. The system can be manipulated by an optimist or pessimist.

Presumably "optimist" and "pessimist" here do not have their ordinary meaning. —Tamfang (talk) 00:01, 18 January 2011 (UTC)

I think "optimist" means "can make a preferred candidate win" and "pessimist" means "can make a non-preferred candidate lose in favor of one of a set of preferred candidates", but the jargon's a little hard to parse. If "anyone but Bush" voters can prevent Bush from winning, that's pessimistic manipulation; and if Gore voters can make Gore win, that's optimistic manipulation. I could be wrong. See page 4 (306) of for the exact definition. (talk) 08:17, 17 January 2012 (UTC)
