Context is the big one. Information has context within its field and outside of its field. You typically require information for some sort of application, and without context, you might end up being inefficient, or worse, repeating something dumb. Cultural context matters too if you are solving a problem that involves people.

Fields interconnect, and knowing how one piece of information relates to information in other fields can improve its utility. A number of technological advances came from applying a solution in one field to a problem in another. For example, before software could do it, bridges were modeled in electrical circuitry before building them to test for resonance conditions.

Any given piece of information has other pieces of information of all different qualities that are related to it. Having a grasp of those relationships is what constitutes knowledge. That's why we say: "A little education is a dangerous thing."

It's not often appreciated, but the humanities provide training to navigate these interconnections, because to do so is art, not science. It is not technical skill alone that differentiates the leaders in a field from the rest. Technical skill is just part of the equation.

If you want to be an expert at something yet remain a fool, you have a much better chance in STEM than in the humanities. :)
