The Anthropic Principle notes that Anthropic Bias is, by definition, the natural expression for universal scale favoritism toward humans.
Bostrom introduced the Self Sampling Assumption in an attempted extension of the Copernican Principle into the time domain, but its been proven that this is of no significance to real world cosmology, becasue theories of everything that have constrained prarameters guarantee the emergence of man in a world in which the humman-system contributes to the predominant observed incilination of the universe, indicating that a strong anthropic principle does indeed exist for good physical reason.
This gets reinforced by the fact that other sciences also recognize the common logical algorithm that produce theories with a logical function that is similar to that of the anthropic cosmological principle, like Benford's Law, in statistics, as well as the law of entropy production, to name just a couple of many that are commonly known.
Nick Bostrom's ideas are interesting and relevant where apparently chaotic, (subtly determined), scenarios are applicable, but he fails to take into account the fact that an anthropic explanation for the fine-tuning of the universal constants is supposed to be embedded into humans by the universal scale mechanism that enables or requires human existence. That justifies the selection effect, in this case, because anthropic bias is supposed to be an innate characteristic of the universe.
Nick seems to be saying that anthropic bias is unwarrented, because the interpretation of evidence is necessarily subjective, and is subject to observational selection effects, but this human-slant is perfectly necessary and justified if the universal scale mechanism behind the anthropic coincidences can be identified and then independently supported by the most conservative representation our best cosmological theories.
The Anthropic Principle then becomes a very powerful reciprocating source of support for the validity of those theories, rather than a continual nagging thorn in their side.
Nick Bostrom tries to eliminate anthropic bias by way of relativism and random observation, but 'The Coin ISN'T Fair' if there is frame independent mechanism that acts in favor of intelligent life.
I disagree with his erroneous claim that, "existing methodology does not permit any observational consequences to be derived from contemporary cosmological theories"... and this is why:
He correctly notes that there can be areas of low entropy, (which are necessary to life), within the greater whole of our entropic, expanding universe, but he failed to equate the predominant entropic prejudice of our universe to the anthropic bias, as supported by conventional Big Bang Theory and The Standard Model of Particle Physics.
A valid natural design hypothesis can be derived from the anthropic bias of Entropic Favoritism toward intelligent life, where it is observationally proven that order increases with the potential for grand-scale entropic efficiency. Nick gives prejudicial credence to Big Bang Theory and the Second Law of Thermodynamics, but he misses the fact that human intelligence enables a highly efficient mechanism for satisfying the second law of thermodynamics on a universal scale, and this was and still is, (since the big bang), the predominant inclination of every object in an expanding universe, ultimately. This tendency was instilled into every object at t=10^-43, so an entropic anthropic explanation is the default position, because it is the most natural in context with conventional Big Bang theory and the Standard Model of Particle Physics.
There is no way to set yourself apart from this because the underlying direction of all action in a big bang induced expanding universe is ultimately entropic, per conventional Big Bang Theory as supported by the latest confirmed observational evidence. Any occurrence within the system is, therefore, a result of the tuning of the constants that were set at t=10^-43. This includes humans in all their glory, and the weak entropic anthropic argument would support this via the fact that it is observationally proven that the human is comparitively one of nature's more preferred methods for satisfying the second law of thermodynamics... on a grand scale.
But humans also represent a very specific path of action toward the pure symmetry of the universe, having the capability to produce particles from the energy of the vacuum, (per quantum theory, as proven in the lab by way of the creation of Dirac's, antiparticle). There are only three known systems in nature that have the capability for this form of contribution to the effort toward idealistically pure symmetry; The Entropy of a Neutron Star in the formation of a Black Hole, Black Hole Entropy, via, "Hawking Radiation". Humans are the only other known system capable of isolating the release of enough energy to create real particle/antiparticle pairs.
According to conventional big bang theory the need for human entropic efficiency has necessarily pre-existed in our universe since the forces decoupled and caused the event to occur over time due to these less-than-perfect results. The principle of least action on a grand scale in an expanding entropic universe requires that "asymmetries" or imperfections in the energy at the moment of the Big Bang are the reason for every increase in the potential for entropy in our universe for the duration of the event, as supported by an entropic anthropic principle, which indicates that "imperfections" are convolved perpetually forth to higher orders of entropic efficiency, per human evolutionary theory.
The coin can never be fair as long as the universe expresses a predominant grand-scale entropic prejudice.

I received this in an email whose author shall remain anonymous, unless I hear otherwise:
Eugene Wigner, winner of the Nobel Prize for physics in 1963, wrote about the �unreasonable effectiveness of mathematics in the natural sciences� and the unreasonably important role it plays in physics. �Laws� of nature are mathematical transpositions of the inferences of science, and mathematics is representative of all that is known about the interactions of elementary
particles. But this is, nonetheless, an ill-understood act of faith, because regardless of the aesthetics of their mathematical
elegance, these models are only as true and accurate as the inferences that support them. Mathematics, by itself, does not
explain anything.
The obvious flaw in that logic is that it presumes that the math supports that the
"inferences of science" are just inaccurate human contstructs,
rather than a reasonably good reflection of reality, and also it conveniently ignores the fact that humans are a part of nature too. By virtue of that fact, the human reflection of nature necessarily isn't nearly as "flawed" as "purists relativists", (aka... "Chaosionists") would like to "believe", (This not to imply that the author of the paragraph fits that mold, which, as I understand it, is not the case).
The definition of the Preferred Theory:
~The most accurate, (not perfect), reflection of nature, in the least possible number of steps~
The reflection is necessarily not perfect, due to the flawed human interface, but experimental vindication to extremely high degrees of accuracy says that our best reflections are very nearly perfect to an extremely practical degree of relevance! That defines entropic efficiency.
The entropic interpretaion gives the real, hard, physical causal mechanism for the cosmic coincidences that produce the Anthropic Principle, and there's nothing "religious" nor "tautologous" about that.
