Today marks the fiftieth anniversary of the assassination of President John F. Kennedy. Just as notably, it has been almost 53 years since his inauguration. The video above shows his inaugural address as well as his swearing-in by then Chief Justice Earl Warren (later of the Warren Commission).
At the beginning of the video, just after Kennedy takes his Oath of Office, he shakes Chief Warren's hand, then Lyndon Johnson's - and then Richard Nixon's. What follows is a short-lived but significant alpha display by Nixon with Kennedy re-asserting his dominance. JFK examples here (0:45 - 0:49) one method by which the "double-hander" can be countered.
Initially, Kennedy should have first turned his body more completely before reaching for Nixon's hand.
Nixon immediately uses both hands to rapidly configure in the "Politician's Double-Hander". Unfortunately this variety of handshake is ingrained in most politicians' body language repertoire. It sends signals of dominance - (or attempts at dominance) and is very negatively received by most people.
Kennedy begins to turn in order to fully face Nixon.
Kennedy continues to turn
Kennedy is now nearly fully "squared" to Nixon, with his face, torso, hips (and feet - very important though not visible here) towards Nixon.
Kennedy's left hand begins to reach up to grasp Nixon's right arm.
Nixon continues his double-hander.
Kennedy is now asserting counter-dominance over the man he had just defeated in the 1960 election by gripping the former V.P.'s right arm.
Nixon pulls away his left hand - far away (over-compensating much as an over-steering event while driving) leaving him with significantly less alpha. Kennedy now has the dominance advantage while continuing to grasp Nixon's right arm.
Both men now disengage their handshake, however Kennedy continues to assert his Presidential dominance by still holding Nixon's right elbow - and in effect "getting the last word".
