Transparency International Malaysia president Dr Raymon Ram said the greater concern was whether agencies would use polygraph testing as a visible response to integrity concerns while failing to address deeper governance weaknesses.
PETALING JAYA: Polygraph testing risks becoming a cosmetic anti-corruption measure if enforcement agencies adopt it without wider institutional reforms, said Transparency International Malaysia president Dr Raymon Ram.
He added that polygraph testing may have value as a supplementary screening or interview option in narrowly defined high-risk settings, but should not be treated as a primary integrity safeguard.
“The scientific evidence surrounding polygraph reliability remains contested, and there is no consensus that it can accurately determine honesty, integrity or corruption risk on a standalone basis,” he told theSun.
However, Raymon said the greater concern was whether agencies would use the method as a visible response to integrity concerns while failing to address deeper governance weaknesses.
“Integrity within enforcement agencies is built through strong institutions – effective oversight, verified asset and interest declarations, robust conflict-of-interest controls, protected whistleblowing channels, professional internal audit functions and consistent enforcement of disciplinary measures.
“No technology or screening tool can substitute for these fundamentals.”
He said any use of polygraph testing should operate within a clearly defined legal and governance framework, supported by independent oversight, transparency, regular reviews and safeguards against misuse.
Polygraph results should not be allowed to determine a person’s career or disciplinary outcome on their own, given the risk of false positives and false negatives, he added.
“Polygraph results should be treated, at most, as one supporting indicator and should never be the sole or decisive basis for recruitment, promotion, disciplinary action or findings of misconduct.
“With the ongoing debate over reliability and the risk of both false positives and false negatives, using polygraph outcomes as a determinative employment or disciplinary tool would raise significant concerns relating to fairness, due process, reputational harm and potential abuse.
“Decisions should be based on objective evidence such as financial records, procurement documentation, digital forensic evidence, witness testimony, unexplained wealth indicators and corroborating documentation.
“Ultimately, institutional credibility depends on decisions being grounded in evidence, due process and transparency rather than reliance on any single screening technology.”
Raymon said agencies should prioritise verifiable, system-based integrity controls that address corruption risks at their source, including asset, income and conflict-of-interest declaration systems.
Such declarations should be verified, reviewed periodically and backed by meaningful penalties for non-compliance, he said.
He also called for stronger whistleblower protection through secure reporting mechanisms, while urging agencies to invest in internal controls, audit functions and corruption risk management programmes.
Targeted job rotation could also help prevent corruption in high-risk areas such as procurement, licensing, enforcement, inspections, investigations and border control, he added.
On lifestyle audits, Raymon said they could be useful when there were reasonable grounds to examine discrepancies between an individual’s lifestyle and legitimate income, but must be intelligence-led, proportionate and independently supervised.
“Without independent oversight, even well-designed integrity tools can be misused.”
