OK, so, would it be fair to set the things into two categories:
Active deception:
The batsman gloves a ball to short-leg, and immidiately points to his hip-bone, which the ball has glanced on it's way. The Umpire adjudicates not-out.
The wicketkeeper dives forward to take a big nick, and scoops it up just a split-second after it strikes the ground. He holds the ball high, celebrates with his team-mates, and nods at the Umpire, who looks at him. The Umpire raises his finger.
Inactive \ passive deception:
The batsman gloves to short-leg; he stands still, waiting. The Umpire stands immobile behind his dark blue spectacles.
The slip-fielder sees the ball strike the edge and dives forward, scooping the ball just after he clearly sees it hit the ground. He throws it up in a melancholy sort of way, while the men around him jump up and down. The Umpire doesn't hesisitate, and immidiately lifts the finger. The slipper joins-in his team-mates' celebrations.
That acceptible to you?
