Scientists have developed a lying detector that detects micro-expressions using AI!

Researchers believe it may be used in the private sector to evaluate insurance claims or employment applications, for example.

Scientists have developed a new lie detector that can detect facial muscles that individuals are unaware of.

The study was published in the journal ‘Brain and Behaviour’ by Tel Aviv University academics.

It was carried out using micro-expressions that disappear in 40 to 60 milliseconds, therefore precision and speed were essential.

“It’s not perfect, but it’s lot better than any existing [facial recognition] system,” says behavioural researcher Dino Levy.

“Because this was an initial research, the deception was quite basic,” he continued.

The give-away markers were evaluated on 48 patients who displayed tell-tale signs such as twitching eyebrows or facial muscles.

“We were able to detect falsehoods in all of the individuals, and we did it substantially better than untrained human detectors,” says Levy.

“It’s worth noting that those who were effective in deceiving their human counterparts were also badly recognised by the machine-learning algorithm,” he said.

Artificial intelligence powered the lie detector, which aims to increase transparency. It can also be used to tighten border controls.

Researchers believe it may be used in the private sector to evaluate insurance claims or employment applications, for example.

Human rights organisations frequently criticize them, questioning the technology’s capacity to properly detect people’s intents and its discriminatory potential.
