We've probably heard enough about the 2012 Rule change to 18-2b that introduced a new Exception to the Rule.  The Exception absolves the player from penalty under 18-2b if it is known or virtually certain the player did not cause the ball to move.  Just as we have a Decision to help us understand the meaning of virtually certainty with regards to a ball in a water hazard (see Decisions 26-1/1 and 26-1/1.3), we also have a Decision that helps us understand virtual certainty with regards to Rule 18-2b's new Exception.
  In Jordan Spieth's case, his ball settled down into a spike mark after he had addressed the ball.  He is certain that he did not cause the ball to move, but there was no other agency besides gravity that could have caused the movement of the ball.  Decision 18-2b/11 explains to us that in order to determine virtual certainty that a player did not cause the ball to move, it must be known or virtually certain that another agency DID cause the ball to move.  And when determining other agencies gravity is not an agency to be considered under this Rule.  Spieth was subject to a one-stroke penalty under Rule 18-2b and had to replace the ball.
