<DIV>Yep, quite correct statement,<BR><BR>but <I>the basic assumption while talking about group</I>'s both action and performance is that the group <I>has the same</I> cost (fitness, objective, loss, merit, etc) function. In other words, that it works under same norm. (In science, the norm used is typically to get better results, meaning the result closer to the 'truth', or closer to the true state of the nature as perceived by the group. Important is that each individual works under same norm, which is often the case in 'science').<BR><BR>If, on the other side, subgroups of the group (and there may be 2,3, ..., up to |group| ) have different objective functions, group will rarely be better than many individuals. Example given below is a great one!<BR><BR>On 23-Dec-11 5:02 PM, Irving Engelson wrote:

In this paper they offer some overview of collective intelligence (attached below):
Evidence for a Collective Intelligence Factor in the Performance of Human Groups
Anita Williams Woolley, Christopher F. Chabris, Alex Pentland, Nada Hashmi, and Thomas W. Malone
Science 29 October 2010: 330 (6004), 686-688.
http://dx.doi.org/10.1126/science.1193147
Their results show that groups of people work better not depending on the intelligence of individuals, but on how efficiently they interact. There is an interesting 6 min related TED talk at http://www.ted.com/talks/tom_wujec_build_a_tower.html
I believe that Prof. Weng generalized the question: any cognitive system can be divided into components, usually the properties of the system are different than those of its components (e.g. neurons+molecules+energy), but we usually do not refer to properties of a brain as "group intelligence", even when it is indeed product of a collection of neurons, etc. It is just a convention.
