Many old throttle lever systems would prefer the closed position if left to their own devices. Perhaps there is the odd system which would go the other way. So throttle levers always had friction adjustments which would be set for take off and then backed up by the other pilot if there was one.
Carrier pilots though take extreme care to remove their hands from the power lever/s before a catapult launch as the g of the launch will result in a substantial reduction in power and an ungainly wet plunge off the sharp end.
