Query: A Not-So-Fundamental Limitation on Studying Complex Systems with
  Statistics: Comment on Rabin (2011)   Although living organisms are affected by many interrelated and unidentified
variables, this complexity does not automatically impose a fundamental
limitation on statistical inference. Nor need one invoke such complexity as an
explanation of the "Truth Wears Off" or "decline" effect; similar "decline"
effects occur with far simpler systems studied in physics. Selective reporting
and publication bias, and scientists' biases in favour of reporting
eye-catching results (in general) or conforming to others' results (in physics)
better explain this feature of the "Truth Wears Off" effect than Rabin's
suggested limitation on statistical inference.
