The first polygraph chart presented above is that of an actual test on a bunker surveyor. The case arose because of disagreement with the figures contained in the measurement report. Question Q3 is "Did you deliberately falsify any of the figures for your bunker survey on vessel ABC (not the real name) on dd/mm/yyyy?" Question Q5 is "Were you offered a bribe for the bunker survey on vessel ABC on dd/mm/yyyy? Question Q8 is "Did you receive a bribe for the bunker survey on vessel ABC on dd/mm/yyyy? The answer was 'no'. The rest of the questions shown are technical questions. Deception was indicated on all the 3 crucial questions. A follow-up test was conducted to find out the amount of bribe received.
