To correct wrong ideas about usability (or anything else, for that matter), you had better not repeat the wrong idea you are trying to correct.
The University of Michigan found that 3 days after reading an article from the CDC aimed at correcting myths about the flu vaccine, participants misremembered 40 per-cent of the myths as facts.
So the best way to correct ideas about, say, user’s willingness to scroll down a page, is to say, “Users are perfectly willing to scroll.” And leave it at that. Don’t handicap your readers by re-stating things that are false.
