"A foil (also called a distractor) is a deliberately false answer option or question that you include in a screener or survey. A foil is just as plausible as the real answer options and questions, but its job is to reveal participants who are: Clicking through without paying attention Guessing in order to qualify for the study Misrepresenting themselves intentionally"
"Foil answer options are the more common approach. For example, imagine you're aiming to recruit people who use cloud-storage services. The answer options might include: Google Drive Cloudbox Ultra Dropbox Microsoft OneDrive "Cloudbox Ultra" is the foil because it doesn't exist in the real world, and it would be a red flag if someone selects it. This could indicate that the respondent is speeding through or hoping to game the system. In either case, their responses are unlikely to be trustworthy or reliable."
A foil is a deliberately false but plausible answer option or entire question included in a screener to reveal inattentive, guessing, or intentionally misrepresenting participants. Foils can appear as single bogus answer choices or as whole fictitious questions that qualified participants would skip or negate. Example answer-option foils include a non-existent product like Cloudbox Ultra; selecting it signals low-quality responses. Full-question foils require more subtlety because they risk appearing implausible. Foil answer options tend to blend in more naturally and often provide a quick, reliable flag for disqualifying untrustworthy respondents prior to running a study.
