Carlos -- I know of cases where groups get worse ideas than many of
its individual e.g., the US Congress. <span class="moz-smiley-s2"><span>

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 <a class="moz-txt-link-freetext" href="http://www.ted.com/talks/tom_wujec_build_a_tower.html">http://www.ted.com/talks/tom_wujec_build_a_tower.html</a>
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.
