My gut feel is that Bayesianism is one of the many useful tools in research, but it is no substitute for education, experience, creativity, patience or tenacity.

This is like saying that "intelligence is no match for a gun" -- as if guns grew on trees (to use an EY-ism). Your idea of "Bayesianism" is far too narrow, as if it meant a specific tool (in fact you refer to it as such), rather than a way of life, which is closer to what it means in the context of LW and EY's Brennan universe. Instead of "Bayesianism", perhaps you should substitute "the rationality culture promoted by LW".

If you do it right, you will of course make use of education, experience, creativity, patience and tenacity; and more.
