title: False, trivial, obvious: why new and revolutionary theories are typically disrespected.
abstract: An old joke about the response to revolutionary new scientific theories states that there are three phases on the road to acceptance: 1. The theory is not true; 2. The theory is true, but it is unimportant; 3. The theory is true, and it is important - but we knew it all along. The point of this joke is that (according to scientific theorists) new theories are never properly appreciated. The 'false' phase happens because a defining feature of a revolutionary theory is that it contradicts the assumptions of already-existing mainstream theory. The second 'trivial' phase follows from a preliminary analysis which suggests that the new idea is not in fact contradicted by the major existing evidence, but the new theory seems unimportant because its implications do not seem to lead anywhere interesting when explored in the light of current theory. A stronger version of this second phase happens when the implications of a theory are regarded as not merely unimportant but actually dangerous, because a scientific revolution is certainly destructive (especially of established reputations) yet its potential benefits are conjectural. However, once a new and revolutionary theory is in place, its importance is 'obvious' such that it becomes hard to imagine how anybody could ever have believed anything else. Theory for scientists is like water for fish: the invisible medium in which they swim. Observations and experiments, on the other hand, are like toys in the fish tank. New toys are attention-grabbing; but when the tank gets cloudy, its water needs changing.
