Individuals and random events are the bane of their predictions, causing radical changes without any way to predict it beforehand. However, the Forecasters have begun to learn how to deal with even them, as there seems to be some ways to approximately factor them. Another problem is groups who attempt to avoid being predicted or use predictive methods themselves, since they cause feedback in the calculations. Sometimes this stabilises things and makes everything much more calculable, but most of the time it just destroys the accuracy of the trends. This is a great limitation, since it makes it very hard to predict the future developments of the Technocracy itself and the Traditions.
Much work is underway to find a solution.
Beside modelling the future, the Forecasters also study how to model individuals, organisations and economical systems. Using their advanced psychological models and all available information about a person, they can create a simulation of the person and test how he or she will react in different situations. They can find weak points, use the simulation to improve their models and develop rather accurate psychological profiles. The same is true for larger groups, which are much easier to predict. Progenitors use their models to predict the development of organisms, Iteration X and the Void Engineers use their models to plan future technological and scientific progress.
