Descriptions are closer to the first order facts than inferences.
For example, you leave the mall but can't find your car. We would label this a description. We merely reported the known data without adding data that were not abstracted. As we move to higher levels of inferences in our daily abstractions we trek on less firm ground. But one who is conscious of abstracting can do this without the negative consequences of ones who are not, because those who are conscious of abstracting will treat their inferences as inferences and not the first-order facts, so will be less likely to act on them hastily and more likely to look for additional data to test the inferences.
