  It has been observed people tend to have opinions that are far more
internally consistent than it would be reasonable to expect. Here, we study how
that observation might emerge from changing how agents trust the opinions of
their peers in a model for opinion dynamics with multiple issues. A previous
Bayesian inspired opinion model for continuous opinions is extended to include
multiple issues. In the original model, agents tended to trust less opinions
that were too different from their own. We investigate the properties of the
extended model in its natural form. And we also introduce the possibility the
trust of the agent might depend not only on the specific issue but on the
average opinions over the many issues. By adopting such a ideological point of
view, we observe an important decrease in the spread of individual opinions.
