Costs rose and delays ensued as organizers realized they needed more information and materials from the original authors; a decision to have the proposed replications peer reviewed also added time. Organizers whittled the list of papers to 37 in late 2015, then to 29 by January 2017. In the past few months, they decided to discontinue 38% or 11 of the ongoing replications, Errington says. (Elizabeth Iorns, president of Science Exchange, says total costs for the 18 completed studies averaged about $60,000, including two high-priced "outliers.") One reason for cutting off some replications was that it was taking too long to troubleshoot or optimize experiments to get meaningful results... So far, the project has published replication results for 10 of the 18 studies. "Five were mostly repeatable, three were inconclusive, and two studies were negative, but the original findings have been confirmed by other labs," reports Science Magazine. "In fact, many of the initial 50 papers have been confirmed by other groups, as some of the RP:CB's critics have pointed out."
