“Statistics about other copies of a team make it harder for team members to deceive themselves about their past performance or their chances for future performance. Such ems may become more like chess players today, where objective performance measures (i.e., their rating) force them to accept their current performance and abilities. This tends to make such players less happy, as they can't pretend to be better than they are. If this happiness effect reduced em productivity sufficiently, ems may adopt attitudes such as "never tell me the odds", often avoiding information about their relative chances of future success.”
