Because it's a fair test

No, not even by Eliezer's standard, because TDT is not given the same problem than other decision theories.

As stated in comments below, everyone but TDT have the information "I'm not in the simulation" (or more precisely, in one of the simulations of the infinite regress that is implied by Omega's formulation). The reason TDT does not have this extra piece of information comes from the fact that it is TDT, not from any decision it may make.

Right, and this is an unfairness that Eliezer's definition fails to capture.

At this point, I need the text of that definition.

The definition is in Eliezer's TDT paper although a quick grep for "fair" didn't immediately find the definition.
