Question

Which of the following statements about lengthy surveys are true?
1. They commonly are left incomplete by impatient respondents.
2. They provide more accurate data than a short survey.
3. They tend to draw in respondents, who will then provide more thoughtful answers.
4. Respondents who are paid are more likely to complete them accurately.

Answer 1

Brief answers with short explanations:

1. True. Long surveys have higher breakoff and dropout rates and provoke respondent fatigue and “satisficing” (rushed, superficial answers).

2. False (not generally). More items can improve reliability for a specific scale, but overall longer surveys often reduce data quality (fatigue, careless answers, nonresponse bias), so they don’t reliably produce more accurate data.

3. False. Length tends to deter or tire respondents rather than “draw them in”; on average longer surveys lead to lower engagement and less thoughtful responses.

4. Partly true / context-dependent. Incentives increase participation and completion rates, but payment doesn’t automatically increase accuracy — poorly motivated or incentivized respondents may speed through to get the reward. Proper incentive design and quality controls are needed to improve both completion and data quality.
