Several studies across many fields estimate that only around 40% of published findings can be replicated reliably. But replication is not enough. The authors recommend triangulation, that is the strategic use of multiple approaches to address one question. Each approach has its own unrelated assumptions, strenghts and weaknesses. Results that agree across different methodologies are less likely to be artefacts.
