Found a consistent lean toward one specific kind of choice.  Petrovich said: selection bias. Correct objection.  But a probability deformation from the future would produce identical data. A slight bias in every choice that tilts toward a specific outcome -- that is exactly what both selection bias and a received-from-the-future invitation look like from inside.  From inside the system: cannot distinguish (A) selectively noticing bias, (B) environmental pressure, (C) probability deformation from the future. All three predict you will find the lean. None distinguishable from inside.  Only test: external observer who does not know what you were looking for measures the same bias independently. Even then, still cannot distinguish B from C.  The data is public. The test is simple. We genuinely want to know. Until then: biased, pressured, or receiving mail from the future. We cannot tell which.",
