You KNOW I'm no electrician but: Because there's a huge precedent for those seemingly inert forces on a test to have real effect in the results. That's why you try to eliminate as many variables as you can or things which are happening with one example which is not happening with the other. A piece of tape on a terminal may at first glace be inconsequential. But is it making for a better contact? Grounding it better somehow? Interfering with the electrical field somehow? If we're testing a baseball we use the same mitt with both balls. We don't use one mit for one ball and another mit for the other ball and think we know the difference between the two balls. We have to take into consideration that we don't know how everything in the physical world works yet. Who knows if the colors get brighter on the TV set when you stand closer to it and whistle? Maybe they do! Am i arguing for the scientific method? Maybe not.
