So, if a category ABC includes A, B, and C, one would expect the total, ABC, to be the same as A, B, and C measured separately. But it isn’t always. When human decision-making is factored in, the sum of A, B, and C measured separately will almost certainly be greater than ABC. That is called the “unpacking bias” – when a category is subdivided into parts, then a separate consideration of each of those parts will be greater than the consideration given toward the category when treated as a whole, rather than unpacked.
