group intelligence seems not uniformly true across subject matters:
from little-known domains (e.g., science) to common-knowledge (e.g.,
raising tax). <br>
<br>
Laymen and peers are almost always falling behind with new
discoveries of science. Here are just a few examples among a long
list:<br>
- Nicolaus Copernicus and

Galileo Galilei's
<meta http-equiv="content-type" content="text/html;
charset=ISO-8859-1">
Heliocentrism,<br>
- Charles Darwin's theory of evolution, <br>
- Albert Einstein's theory of relativity, <br>
...<br>
- peer reviews for paradigm-shift papers and proposals.<br>

you might be interested in this follow-on to my Science paper. We
found that 50% of the `collective intelligence' (objective
performance) of a group can be predicted by the pattern of
interaction alone. Similar results hold in real-world situations
(companies, etc) that we have analyzed. <br>

In this paper they offer some overview of collective intelligence (attached below):
Evidence for a Collective Intelligence Factor in the Performance of Human Groups

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 moz-do-not-send="true" 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.
