Recent high-profile cases of scientific fraud have demonstrated that scientists are only human too and sometimes individual scientists falsify their data. Since science is the basis of decision- and policy-making, we all should be able to scrutinise scientific studies. Here, we provide practical guidance and concrete tools for forensically examining scientific data and identifying potential cases of data manipulation. These approaches will enable and empower audience members to independently perform forensic plausibility checks on scientific data, as well as provide a starting point for their further, independent study. Limitations and ethical considerations when performing such analyses will also be discussed.
