The effective coupling `constants' of physics, especially the cosmological constant, are observed to have highly biophilic values. If this is not a hugely improbable accident, or a consequence of some mysterious logical necessity or of some simple principle of physics, it might be explained as a consequence either of an observership selection principle within a multiverse of many sets of effective coupling constants, or else of some biophilic principle that fine tunes the constants of physics to optimize life. Here a very preliminary inconclusive hint of evidence is presented against the hypothesis of optimal fine tuning of the cosmological constant by a biophilic principle that would maximize the fraction of baryons that form living organisms or observers.
