An incomplete comparison is a misleading argument popular in advertising. For example, an advertiser might say "product X is better". This is an incomplete assertion, so it can't be refuted. A complete assertion, such as "product X sells for a lower price than product Y" or "the new product X lasts longer than the old product X" could be tested and possibly refuted.
In grammar, incomplete comparison, is a comparison that leaves out one of the item being compared. Unacceptable: Learning Chinese is more difficult. Acceptable: Learning Chinese is more difficult than learning Spanish.
Famous quotes containing the words incomplete and/or comparison:
“Someone once asked me why women don’t gamble as much as men do, and I gave the common-sensical reply that we don’t have as much money. That was a true but incomplete answer. In fact, women’s total instinct for gambling is satisfied by marriage.”
—Gloria Steinem (b. 1934)
“When we reflect on our past sentiments and affections, our thought is a faithful mirror, and copies its objects truly; but the colours which it employs are faint and dull, in comparison of those in which our original perceptions were clothed.”
—David Hume (1711–1776)
