Researchers at the National Center for Credibility Advancement, the US military's "premiere educational centre for polygraph and other credibility assessment technologies and techniques," studied whether potential government job applicants would admit more to a computer-generated avatar versus self-reporting on a paper or computer questionnaire. They created a talking head avatar and gave it an automated dialogue tree of questions.
The researchers tested the automated avatar on a group of 120 US Army basic trainees sitting for a mock national security clearance interview. As the authors put it, they "examined behavioural and physiological responses of individuals to questions concerning their mental health, drug, alcohol, and criminal histories."
Surprisingly, even though the computer avatar isn't that convincingly human, volunteers divulged much more to the talking head than they did to a questionnaire. And when the avatar asked "is there anything else," over 10 per cent of subjects added further information.
It's a little creepy to think that the government wants to replace interviewers with avatars, but there's a very pragmatic reason for it: the researchers point out that automated interviews would be less "time consuming, labour intensive, and costly to the Federal Government." Add to that the strange realisation that people are somehow more comfortable revealing secrets to a screen, and you can see why the government might want to use virtual reality to vet its applicants.
