the claim

Body language is a reliable indicator of deception.

the verdict
REFUTED
the evidence says no
Recorded sources
0 sources for · 6 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that body language is a reliable indicator of deception?

No. Multiple reference and peer-reviewed sources state that research finds no reliable nonverbal indicators of deception and that people detect lies only slightly above chance. One review paper advocates body language for lie detection but does not demonstrate reliability.
