Ah, ok. I see what you meant now; it's because even the thought was taken out of the blue, and a choice should be founded on something regardless of whether it's open-minded or not.
I'd say it's actually very open-minded to consider that something might be true.
It's open-minded to consider it for sure, but that should be followed by research and a decision made based on actual facts, not suppositions.
For instance, he should have found that ok, only 2‰ of my audience lacks 3.0 enabled cards, and that amount is declining, -then made a decision.
Alright, back to the topic. Pardon my stray into assumption/nonassumptions.
