If you saw Donald Trump introducing his Supreme Court nominee Neil Gorsuch, you may have noticed something odd about the handshake. It started simply enough. Both Trump and Gorsuch extended their right hands for a shake.
Well, according to psychologist and body language expert Dr. Peter Collett, Trump is definitely trying to show dominance. He says that there are two kinds of greetings. There are solidarity greetings, which show that two people are equal. This is indicated by a symmetrical gesture, like the typical handshake (not seen here).
As Trump was moving his left arm to Trudeau's shoulder, Trudeau did the same thing to to Trump's shoulder. Not only that, but Trudeau moved in so close that Trump had no room to yank his arm. This was a brilliant strategic move.
The result? Trump was left without the feeling that he had the upper hand over Trudeau for the rest of their meeting. So if you ever encounter an arm-yanker in real life, try Trudeau's strategy. It just might be the answer.
