As financial planning firms grow more efficient, especially with the use of technology, it becomes possible for planners to manage an increasingly large number of clients. The only limitation, it would seem, is the time it takes to service them. However, research in psychology and anthropology suggests that there may be another limit to the maximum number of clients - the physiological limit of our brain's neocortex that constrains the number of social relationships that can be actively maintained. This threshold - called "Dunbar's number" - is estimated to be about 150 people on average, and corresponds not just to the average size of many ancient tribes and villages, but also the military unit size of the Roman army, and even the average number of Facebook friends or engaged Twitter followers! The implication of the research is that even as firms continue to become more efficient, there's still a physiological brain-based limit to how many clients we'll ever be able to manage, which allowing for some personal relationships as well may never be much higher than 75-125 for any planner regardless of the new tools and technologies we create in the future!Read More...
