Fact-Check: "Benford's Law Can Be Applied to Detect Election Fraud"

What We Know

Benford's Law, also known as the first-digit law, states that in many naturally occurring datasets, the leading digit is more likely to be small. For example, the number 1 appears as the leading significant digit about 30% of the time, while larger digits appear less frequently (e.g., 9 appears less than 5% of the time) (Wikipedia on Benford's Law). This statistical phenomenon has been applied in various fields, including accounting and election forensics, to detect potential anomalies or fraud.

However, several studies have critically assessed the reliability of Benford's Law in detecting election fraud. For instance, a thesis by Brown et al. (2012) concluded that the application of Benford's Law is unreliable for identifying fraud in election results. The authors noted that the law often predicts fraud in scenarios where none exists, leading to false positives (Brown et al. thesis). Similarly, an analysis of the 2020 election data by Kossovsky and Miller found no evidence of fraud when applying Benford's Law to the results (Kossovsky and Miller report).

Analysis

The claim that Benford's Law can effectively detect election fraud is not supported by robust evidence. The studies referenced above highlight significant limitations in using this statistical tool for such purposes. Brown et al. (2012) emphasized that as more sophisticated estimation methods are applied, the results become increasingly inconsistent, often leading to incorrect conclusions about the presence of fraud (Brown et al. thesis).

Moreover, the analysis conducted by Kossovsky and Miller on the 2020 election results demonstrated that deviations from Benford's Law did not correlate with actual instances of fraud. Their findings indicate that the law is not a reliable indicator for assessing the integrity of election outcomes (Kossovsky and Miller report).

In addition to these studies, a Reuters fact-check also pointed out that deviations from Benford's Law do not provide conclusive proof of election fraud, further supporting the argument that the law should not be used as a standalone tool for fraud detection.

The reliability of sources is crucial in this context. The studies by Brown et al. and Kossovsky and Miller are peer-reviewed and published in academic settings, lending them credibility. In contrast, anecdotal claims circulating on social media often lack rigorous analysis and should be approached with skepticism.

Conclusion

The assertion that Benford's Law can be applied to detect election fraud is False. While Benford's Law is a fascinating statistical principle, its application in the context of election fraud detection has been shown to be unreliable and prone to false positives. Rigorous studies have demonstrated that deviations from the expected distribution of digits do not necessarily indicate fraudulent activity, and thus, relying on this law for such critical assessments is misleading.
