People actually bought into the idea of the LVA technology nonsense?
First of all there is no evidence that Bigg Boss even used the actual LVA technology. Its difficult to get your hands on it, and i doubt BB would go to the trouble just for a segment on their show.. And BB didnt show any independent verfiier for LVA..
Secondly even if they used LVA,it dosent mean anything. Because it is NOT a lie detecting test. The technology has been debunked by various organisations who did tests and studies and even by USA's Homeland Security.. Studies have shown that it simply dosent work and its results are as good as something of just 'chance'..
The polygrah machine (lie detecting machine) is scientifically the most effective device for lie detection and even that is not 100 %.
Layered voice analysis is absolute bullshit and pseudo science.. its as effective as looking into the crystal ball for informaton about the future..
And in all probability it was just someone from production pressing a red or green button backstage,,,
The number of people who will believe any nonsense is astounding...
