To me it seems nakedly obvious that "God faked the details of evolution" is a far more outre and improbable theory than "our universe is a simulation and the simulation is approximate". I should've been able to leave filling in the details as an exercise to the reader.

Trusting ones 'gut' impressions of the "nakedly obvious" like that and 'leaving the details as an exercise' is a perfectly reasonable thing to do when you have a well-tuned engine of rationality in your possession and you just need to get some intellectual work done.

But my impression of the thrust of the OP was that he was suggesting a bit of time-consuming calibration work so as to improve the tuning of our engines. Looking at our heuristics and biases with a bit of skepticism. Isn't that what this community is all about?

But enough of this navel gazing! I also would like to see that digression on Solomonoff induction in an anthropic situation.
