It seems to me that societies frequently construct systems that may be too complicated for any individual to operate competently within. For example, the tax system, the legal system, the medical coding system, etc. I have intuitions about how one might detect if any given system is too complex. For example, a lack of consensus in how to perform system specific tasks (e.g. filling out a tax return), a large error rate among system task performers, a failure of system participants to get better over time. I am interested in reading research in this area, if any exists. Can some one provide me with suggested readings?
