Wouldn't it be great if people were like Pinocchio and their noses got longer when they

These days, you'd think that technology could solve this problem but it hasn't so far.

In fact research suggests that low-tech techniques might work better.

The most promising involves wait for it,

Whoa!

That's right, science says that if you want to catch someone in a lie,

anxious with the idea being that lying makes you anxious. The problem is that many truthful

people are already anxious during interrogation, while good liars might not be anxious at all.

Another technology trick comes in the form of the micro expressions training tool or
