Believability in Sender Demeanor
New research, conducted by Human Communication Research , suggests that sender demeanor may be the most influential source of variation in deception detection judgments.
Sender Demeanor is the difference in the believability of a message sent by a “sender”, which is independent of the actual honesty of the message.
In this study, published in Human Communication Research, Volume 37, Number 3, July 2011, sender demeanor induction explained as much as 98% of the variance in detection [of deception] accuracy.
Does the person not the message have a greater impact on what one believes?
Three additional studies investigated the behavior profiles of believable senders. The results suggest a strong impact of sender effects in deception detection.
Do you think that it is too early in the research stage to say that a sender’s believability is the most influential source of variation in deception detection?
