on a cable thread?
OK, more seriously, I think it's safe to say that there's unlikely to be a test which will satisfy everyone. I think there are people on both sides of the issue who will always
find something to object to if the test doesn't go "their way." I mean, can you really imagine any test that would get, say, sovkiller and markl to agree about cables? (Just for example's sake, nothing personal to either one of you.)
Now, if we accept that (and assume some people will be unswayed no matter what) but still believe there are enough people who only lean one way or another but aren't quite religious about it, then yes, there's probably common ground in the middle somewhere.
One problem is that we'd all have to agree what the right question is in the first place, and I think even there we might have some dissent.
Furthermore, I think an important part of the process would be for people to state clearly what they think the results would mean given certain outcomes before
they know which way the data comes out. Hindsight bias is potentially enormous here.
But in principle, I think it's a fun idea to discuss what could be done to be more definitive. And I'd like to reiterate that no matter what, we owe Ed a huge debt for getting the ball rolling...
