Which if?

We earthlings don't like uncertainty. We usually like imagination. My suggestion: rather than depend on a show of confidence, which ultimately is rather empty or illusory, to get attention and credibility where there's real uncertainty, use imagination.

Rather than say, "We just can't draw a firm conclusion based on these numbers and this proposed mechanism," you can suggest alternative explanations that could hold water for all we know. A vivid alternative can appear positive where a statement of uncertainty would appear negative, even though they are basically the same. As a culture, we ought to embrace uncertainty more as the critical spice it is. Until then, though, use imagination?!
