It might not be scientific... But man, a lack of eye contact and/or a less than firm handshake have always been tells to me - it says either over the top insecure or not trustworthy.I was bugged by Beards use of "eye contact" as a measure of sincerity and honesty. I just watched his presser again and MM's presser today. It appears he may be on to something. Marvin looks at people around the room, where Beard looks down and even when he turns to address TKM, he is not really making eye contact. He gave away his own 'tell".
