This depends if your comparing tires that would of locked up or not. If the tires lock up, the breaking force would drastically decrease since the tires are slipping. If the tires would not lock up, the constant pulsing of the breaks produces a lower average braking force compared to no pulsing.
I was kidding.
Clearly the dog on the right was locked up for the full drag.
The idea of ABS is that you don't ever halt the wheel. The system is supposed to detect wheel slowing and release the brake so as to not skid. You're right that a skidding wheel provides less braking force. Thus the average braking for the ABS system (non skidding) is greater than the non-ABS (skidding) system and the dog on the left should have stopped shorter. The joke was supposed to revolve around the fact that dogs don't really have ABS brakes so the ABS/nonABS stopping distance question was absurd. Clearly it didn't work. Sorry.
So how, exactly, does God know that She's NOT a brain in a vat?
