Polygraphs help Indian couples tell the truth

Modern husbands and wives use forensics to get to heart of relationship.

Another contributing factor to the spike in forensics being used to settle husband-wife tiffs is its affordability. Truth Labs charges 5,000 rupees (a little over $100) for a polygraph and the results are available in less than a week. The government’s Center for Cellular and Molecular Biology charges 3,800 rupees (about $80) for DNA profiling.The services are within reach of India’s middle class.

Dozens of cases arrive at the Center for Cellular and Molecular Biology, as well as several other government-run labs, for DNA profiling. But the lab stringently insists on providing paternity tests only if the husband and wife give full consent and arrive with the child to provide blood for the profiling. The lab rejects hair and other material for the test.

“On the one hand, people are more aware that science can help tell the truth,” said Thangaraj, explaining the uptick in DNA profiling in paternity dispute cases. “On the other, you could say that people are losing trust in relationships.”
