The induction between two SPs might be very simple. They may be linked directly. For instance, a sound of a broken glass may be directly connected to a look of a braking glass, because the Neumann that creates these two specific SPs, is always behave like that. But it can be connected in more complex ways, for instance the Neumann that creates these two SPs may be a computer that create a breaking sound, whenever he creates a visual SP of breaking glass. Or this induction may be describe well the relation between the SPs until sometime, and it may be not describe the relation in the future<ref>[http://www.amazon.com/Fact-Fiction-Forecast-Fourth-Edition/dp/0674290712 Goodman, N., & Putnam, H.

The reason to choose the simplest induction is because the number of available possible relations between a sound and a breaking glass are infinite. Therefore for reasons of effective storage, we will use to use the '''simplest induction which is the minimum usage of information to describe maximum sets of SPs'''. In our case it might be ''"All breaking glasses has this specific sound"''.
