Stomach could reveal who is lying

US scientists have found a new, more reliable lie-detector test - by listening to liars' stomachs.
Conventional polygraph tests use changes such as increased heart rates and sweating. The problem with the conventional ones is that people may be anxious because of the test and get exited anyway. A new lie detector would show changes in a gut pattern. Inventors believe this would be a more reliable test.
It is called an electrogastrogram (EGG) and some testings have already been conducted.
While both lying and telling the truth affected the ECG recordings ( conventional testing), the EGG showed obvious changes only when the individual was telling a lie - there was a big decrease in the percentage of normal gastric slow waves.
The thing with a new lie detector is that it uses the same technique that relies on the notion that people become more stressed when they lie. Those who don’t feel guilty about lying may not show such anxiety and will pass the test.
More tests are to be conducted before the test is approved.
