This is not a question of general leanings of the cosmological view that Griaule could have telegraphed. It is a question of a specific detailed cosmological view that is derived in a particular way from a specific type of aligned structure built according to a specific plan, which in each culture evokes matching sets of cosmological and biological symbolism. It can only be the case that either Griaule fraudulently overlaid someone else's cosmology whole as if it were Dogon, or that the Dogon were already in posession of the legitimate, intact cosmology and reported it faithfully to Griaule. There is really no middle ground - he could not have subconsciously led them to this. It would be like me trying to lead you to all the key jokes in a Marx Brothers movie.
