2 Some context-related properties a bridging model might need to include

2.1 (more specific) contexts increase inferential power


The power of contexts is that they greatly restrict the possible inferences so that it is easier to deduce the relevant facts about any particular situation. In addition the context may provide extra facts to be used in any such inference.

For example, when told that a certain car stops if the light is red and that the car stops people often conclude that the light is red. This seems to be because the initial facts also set the context (cars stopping at lights) which, if presumed, allows this conclusion. This is in contrast to trained logicians (when thinking in that mode) who have learned to restrict themselves (as far as possible) to inferences without presumptions and, in particular, without presumed contexts so that they will not be able to make any conclusions in this case.
