Lie detector
A new form of lie detector that works by voice analysis and which can be used without a subject’s knowledge has been introduced in Britain. The Dektor psychological stress analyser is used by private industry for pre-employment screening, investigating thefts, and even periodic staff checks. In the US, the device is used for pre-employment interviews, and for monthly checks with branch managers, asking questions; which at least prevents a manager from setting his own pace to investigate possibly suspicious behavior. Finally, US insurance investigators are now using the PSE. They need not carry it with them - only tape record the interview, usually with the permission of the unsuspecting claimant. But it can also be used to probe a whole range of personal issues totally unrelated to job - union and political affiliations, for example. And, of course, the PSE can be used without the subject even knowing; its inventors analyzed the televised Watergate hearings and told the press who they thought was lying.
