Scientific Utopia: II. Restructuring incentives and practices to promote truth over publishability
Professional success for scientists depends on publishing. Publishing norms emphasize novel, positive results. As such, incentives for professional success encourage design, analysis, and reporting decisions that elicit positive results, and ignore negative results. Prior reports demonstrate how these can inflate the false positive rate in published science (e.g., Greenwald, 1975; Simmons, Nelson, & Simonsohn, 2011). False results can then persist in the literature because of the incentives for novelty over replication, and the unavailability of original data and materials. While the problem is widely understood, little progress has been made to address it. We explain why, and provide suggestions for effective change. The persistence of false results can be reduced by increasing transparency of the entire scientific process, and by capitalizing on the ultimate motivation - getting it right - over the shorter-term incentive - getting it published.
