I think banning politics completely would be a mistake, but maybe I'm wrong. One of the bases for rational thinker is to admit one can be wrong, and to be open to change one's opinion according to available facts. So, from this POV running an experiment and seeing whether no politics makes it better or worse I think completely appropriate. Maybe it'll prove a big mistake - so we'd suffer for a whole week (oh horrors!) or maybe it won't be, and we'll learn something new.
