I've posted on that also. For example the predictions are fighting against butterfly effect, and at best double in time when you square the computing power (and that's given unlimited knowledge of initial state!). It's pretty well demonstrable on the weather, for instance, but of course rationalizers can always argue that it 'wasn't demonstrated' for some more complex cases. There are things at which being to mankind as mankind is to 1 amoeba, will only double the ability compared to mankind at best (or much less than double). The LW is full of intuitions where you say that it is to us as we are to 1 amoeba, in terms of computing power, and then it is intuited that it actually can do things as much better than we can, as we can vs amoeba. Which just ain't so.
I thought Ben Goertzel made an interesting point at the end of his dialog with Luke Muehlhauser, about how the strengths of both sides' arguments do not match up with the strengths of their intuitions:
What do we do about this disagreement and other similar situations, both as bystanders (who may not have strong intuitions of their own) and as participants (who do)?
I guess what bystanders typically do (although not necessarily consciously) is evaluate how reliable each party's intuitions are likely to be, and then use that to form a probabilistic mixture of the two sides' positions.The information that go into such evaluations could include things like what cognitive processes likely came up with the intuitions, how many people hold each intuition and how accurate each individual's past intuitions were.
If this is the best we can do (at least in some situations), participants could help by providing more information that might be relevant to the reliability evaluations, and bystanders should pay more conscious attention to such information instead of focusing purely on each side's arguments. The participants could also pretend that they are just bystanders, for the purpose of making important decisions, and base their beliefs on "reliability-adjusted" intuitions instead of their raw intuitions.
Questions: Is this a good idea? Any other ideas about what to do when strong intuitions meet weak arguments?
