Last week, Imperial College London, in collaboration with Nature, hosted a conference on a subject that’s rarely talked about in science: failure. The success of a conference on failure didn’t go unremarked, but beyond the meta-humour there was plenty of opportunity for serious discussions.

Science is built on failure in several ways. Scientific ideas and hypotheses need to be tested, refined or rejected to expand humanity’s knowledge. This means that researchers should expect that an experiment or a project might fail, and know how to navigate the consequences. If scientific progress is the practice of scaling the shoulders of giants, let’s not forget that it can be a slippery climb.
