words -> tell you the message body language -> how confident or uncertain the speaker might be in this example: - Kevin Warsh (Current Fed Chair) says very confident things about Bitcoin - but at some of those moments, he also shrug his shoulders or press his lips together - those body language cues don't mean he's lying, but they can suggest he's: choosing his words carefully, feeling some uncertainty, thinking through a complicated topic... the key point is that when words and body language don't completely match, it's worth paying closer attention want a deeper anaylsis? check out @ArAIstotle's behavioural analysis below
