Conjoint survey designs are now common tools for studying decision-making, but a practical question arises for researchers: how many choice tasks can respondents do before satisficing meaningfully reduces response quality?

📋 How Respondents Were Tested

• Respondents were asked to complete as many as 30 conjoint choice tasks.
• Experiments were fielded on two common survey platforms: Amazon's Mechanical Turk (MTurk) and Survey Sampling International (SSI).

📊 What the Experiments Found

• Detectable increases in survey satisficing occurred as the number of tasks rose, but these increases were quite limited.
• Conjoint designs showed surprising robustness: even with dozens of tasks, response quality did not decline substantially in the study contexts examined.

🔎 Why This Matters

• The results provide practical guidance for survey designers weighing the trade-off between statistical power and respondent burden.
• In similar populations and contexts, researchers can assign multiple—potentially dozens of—conjoint tasks without expecting large losses in data quality, though monitoring satisficing indicators remains advisable.
