Linguistic cues that a person is lying on his/her on-line dating profile.

Discerned by a UW communications prof Catalina Toma:

The more deceptive a dater's profile, the less likely they were to use the first-person pronoun "I."...

The liars often employed negation, a flip of the language that would restate "happy" as "not sad" or "exciting" as "not boring." And the fabricators tended to write shorter self-descriptions in their profiles....

"They don't want to say too much," Toma says. "Liars experience a lot of cognitive load. They have a lot to think about. The less they write, the fewer untrue things they may have to remember and support later."

Cognitive load. What an expression! It suggests a new answer for the old question: "Are you shitting me?"
