An article published by Law.com reports that a federal judge has allowed claims to proceed alleging that Amazon’s “Workstyle Assessment” hiring tool may violate federal restrictions on lie-detector testing in employment screening. The lawsuit claims that the company’s behavioral assessment evaluates applicants in a way that attempts to infer honesty or deception—potentially placing it within the scope of the Employee Polygraph Protection Act (EPPA).
According to the article, the plaintiff alleges that Amazon’s assessment—which asks applicants to respond to statements about workplace behavior and integrity—effectively operates as a modern form of lie-detector testing. The federal judge concluded that the allegations were sufficient to allow the claims to move forward, leaving open the question of whether algorithmic hiring tools that evaluate truthfulness may fall within the statute’s restrictions.
The EPPA generally prohibits private employers from requiring or requesting employees or job applicants to take lie-detector tests, including polygraphs and similar devices, subject to limited exceptions. While the statute predates modern hiring algorithms, the case raises the possibility that courts may interpret older employment laws to apply to emerging workplace technologies.
From a legal and governance perspective, the dispute highlights broader compliance issues surrounding AI-driven hiring and assessment tools. Many employers now rely on behavioral assessments, automated screening systems, and algorithmic decision-making to evaluate applicants. However, these technologies may intersect with existing legal frameworks governing hiring practices, employee privacy, and workplace testing.
From a risk-management standpoint, organizations using automated hiring tools may face exposure if such systems attempt to measure honesty, personality traits, or behavioral indicators in ways that resemble restricted employment testing methods. In addition, opaque algorithmic processes can complicate an employer’s ability to explain hiring decisions in litigation or regulatory proceedings.
The broader takeaway is that as employers increasingly deploy technology to streamline hiring, those tools should be carefully evaluated for compliance with existing employment statutes and regularly reviewed for legal risk—particularly as courts begin applying longstanding laws to modern workplace technologies.
