“Common sense” is just a modern positive term for folk mythology; and particularly when it comes to reading “body language” to detect lies, much of that popular wisdom is based on fabrications deliberately popularized by the law enforcement community (not unlike polygraphy, and, until the same fell apart, the FBI’s “fiber science”.)
Relying on body language (not independent knowledge of the facts of the claim) to detect lies is at best barely better than a coin flip and tends to rely (like polygraphy, which is also not reliable) on indicators of arousal and the known false assumption that arousal = deception, but with less accuracy in detecting arousal than a polygraph.
