Entertaining read. Sometimes the process of exploration may be just as important as the results, and negative results may be just as valuable as positive results. Would save everybody so much time if there was data available about what did not work, rather than only what did work. The PLOS Current seems to be moving in the right direction about what it means to share research. In my discipline of geotechnical engineering, design failures are encouraged to be reported. Historically, that’s how the profession has advanced. There are technical sessions at conferences specifically dedicated to the presentation of case histories, whether they were successes or failures. However, journal articles still seem to be reserved for the so called positive results, and that renders research inefficient a lot of times.
