A novel spatial display for a classic signal detection problem was tested in an experiment with 30 naive volunteers and 2 experts, measuring the signal detection properties of a spatially organised display compared with temporally organised display. The collective performance of committees was also measured. The spatial display was quantitatively and qualitatively superior, resulting in a 4.6% increase in correctness of classifications and a 30.5% decrease in miss percentages. Qualitatively, 83% of participants preferred the new display. The collective receiver operating characteristic performance of the top half of the best performing naive participants was superior to that of most individuals and all experts. However, in an analysis that examined the value added of both the improved spatial display and the collective intelligence approach, the results demonstrated that the bulk of performance gains can be attributed to the improved design, as compared to the value of collective action, by roughly 2:1.
