The Trap of Solid Gold: "Common Denominator"

The Trap of Solid Gold: "Common Denominator": John D MacDonald’s science fiction received little if any critical attention during his lifetime. Besides the book reviews of his three sf novels -- almost all of which appeared in science fiction magazines -- and Martin H. Greenberg’s introduction to his 1978 short story collection Other Times, Other Worlds, I’m not aware of any serious attempt by anyone to come to terms with the body of this material.
