One of the standard methods of science-fiction world-building is to take a current trend and extrapolate it into the future, and see what comes out. One trend I've observed is that over the last century or so, people have kept coming up with clever new ways to find answers to important questions - that is, developing new methods of rationality.
So, given what we do currently know about the overall shape of such methods, from Godel's Incompleteness Theory to Kolmogorov Complexity to the various ways to get around Prisoner's Dilemmas... Then, at least in a general science-fictional world-building sense, what might we be able to guess or say about what rationalists will be like in, oh, 50-100 years?
I have this dream where you have a supercomputer and you feed it all the world's academic papers and so forth and using a set of heuristics it highlights all the parts of the documents that have markers for various confusions, biases, and errors, then it ranks the documents according to some sort of rationality index, and traces all the connections through citations, etc, to produce a complete map of rationality in the sciences. You can immediately see where the clearest thinking is being done, drill down to discover the most rational researchers and even see highlighted sentences that display biases, confusions, errors, etc. All without a hint of intelligence.
I wish I had dreams that awesome and complicated.
