I know one way to deal with this data is to run all of the data (e.g., every participant's answers) and then to run it again taking out suspicious completions (e.g., unusually fast completion times or surveys that have all the same answers) to compare results and make a justification from there. Bit I would like to have literature to both understand the choices I make and to justify them in research manuscripts. I've looked for answers, but I'm finding most survey methods handbooks or guides do not cover this topic.
