All the facts are never in. We don’t have all the facts on the sinking of the Titanic, on the efficacy of social media or on whether dogs make good house pets. We don’t have all the facts on genetically modified food, global warming or the demise of the industrial age, either.
The real question isn’t whether you have all the facts. The real question is, “do I know enough to make a useful decision?” (and no decision is still a decision).
If you don’t, then the follow up question is, “What would I need to know, what fact would I need to see, before I take action?”
If you can’t answer that, then you’re not actually waiting for all the facts to come in.
