Abstract This article develops and empirically tests a quantum probability model for question order effects observed in survey research. First, the general theoretical assumptions are presented; second, an exact parameter free prediction is derived; third, the results from four surveys and one experiment are used to empirically test the prediction; fourth, a new index is derived to measure similarity between questions; finally, we describe the main conditions under which order effects are predicted to occur. In conclusion, quantum theory, initially invented to explain order effects on measurements in physics, provides a powerful explanation for order effects of survey questions too
