revise

I took Drake's equation and I called it a revised Drake Equation.

First, that our beliefs can be expressed as probabilities, and second, how our beliefs should be revised when we obtain more information.

But if we know it’s time for change, it’s much better for us to make a choice and revise it later than to not make a choice at all.

We live in a world of uncertainty, but we always have prior expectations of what might happen next, and we revise that uncertainty as we learn from experience.
