People succumb to motivated ignorance when their goals lead them to avoid learning potentially valuable information.

Making decisions about social issues, including scientific ones such as climate change and bioengineering, requires values as well as facts. One good way to make such values explicit is to diagram them using cognitive-affective maps, which display emotional attitudes as well as conceptual structure.
