Oh absolutely. We don't have time to thoroughly investigate the case for every idea we come across. There comes a time when you say that you're not interested in exploring an idea any further.

But there is an intellectual honesty to admitting that you haven't heard all of the evidence, and acknowledging that you might conceivably have changed your mind (or least significantly changed your probability estimates) if you had done more research.

And there's a value to it as well. Some ideas have been thoroughly researched and should be labelled in our minds as "debunked". Others should be labelled as "not yet disproven". Later, if we happen to encounter more evidence on the topic, we might take this into account when we decide how seriously to take it.

The lady in the story might have sounded much more sensible to us if she had said "Evolution still sounds absurd to me, but I'll admit that i haven't yet given the pro-evolution argument a proper opportunity to change my mind".

And i think we should try to be that sensible ourselves.
