Small Group Dynamics. Small is better because factions can not survive?

There are some interesting assumptions in this theory of the inefficiency coefficient. Stefan Turner says that ineffency goes up in there are enough people to support independent coalitions and factions. However, as the barriers to coordination go down, it would seem that smaller coalitions and factions will be able to sustain themselves with less energy (need less people then in 1933) and we would have increased fragmentation and increased inefficiency which is the opposite of what has happened since 1933.

I am not buying it.


Physicists quantify the 'coefficient of inefficiency' - physicsworld.com

Parkinson, who died in 1993, discovered a strong correlation between a committee’s ability to make a good decision, and its size. In particular, Parkinson found that committees with more than about 20 members are much more ineffectual at making decisions than smaller groups — something he dubbed the “coefficient of inefficiency”.

While many organizations are aware of the 20 person rule, Thurner and colleagues had not been able to find any reference to a mathematical explanation of the coefficient. So they set out to first empirically verify Parkinson’s law and then develop a mathematical model to describe
