📌 Why This Question Matters

Political science survey work has shifted strongly toward computer‑assisted self‑interviews delivered online, where the survey sponsor—often an academic institution—is commonly displayed on the consent form or survey website. It is an open question whether these visible sponsorship cues increase total survey error by changing how respondents answer.

🔎 What Was Tested

This study measures whether visible sponsorship (university vs. marketing firm) affects multiple indicators of response quality:

• Satisficing behavior (e.g., straightlining, rapid completion)
• Demand characteristics (responses altered by perceived study purpose)
• Socially desirable responding (answers biased toward social norms)

The analysis also tests whether any sponsor effects differ with respondents' prior experience with online surveys.

🧭 How the Measurement Worked

• Sponsorship cues were displayed in the initial consent form and/or on the survey website as commonly occurs in online data collection.
• Response quality was evaluated across the three indicators listed above, comparing sponsorship by a university to sponsorship by a marketing firm.
• Variation in effects was assessed by grouping respondents by reported past experience with online surveys.

📈 Key Findings

• No evidence was found that visible survey sponsorship—whether by a university or a marketing firm—affected measures of response quality.
• No differences in sponsorship effects emerged across respondents with different levels of past online survey experience.

⚖️ Why It Matters

These results suggest that prominent displays of academic or commercial sponsorship on online survey consent pages or sites do not measurably increase satisficing, demand effects, or socially desirable responding, alleviating a potential source of concern about sponsorship‑induced bias in contemporary online political science surveys.
