Bertrand Russell famously said "(1) that when the experts are agreed, the opposite opinion cannot be held to be certain; (2) that when they are not agreed, no opinion can be regarded as certain by a non-expert; and (3) that when they all hold that no sufficient grounds for a positive opinion exist, the ordinary man would do well to suspend his judgment." If I abide by these rules, what reason is there for me voting in elections, or even having a political opinion at all?
