See http://en.wikipedia.org/wiki/Collective_intelligence

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.

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.
