in his household (which included Wolverton, one daughter, and several grandchildren) were able to read. The "bad" side of the Kallikak family included poor farmers but also school teachers, an Army Air Corps pilot, and a bank treasurer. It has been argued that the effects of malnutrition were overlooked in the Kallikak family. Goddard's peer, Davenport, even identified various forms of diseases now known to be caused by diet deficiencies as being hereditary. Another perspective has been offered that the Kallikaks almost certainly had undiagnosed fetal alcohol syndrome. In addition to poverty and malnourishment, prenatal alcohol exposure can create craniofacial and other physical anomalies that could account for their peculiar facial features. Furthermore, prenatal alcohol exposure may also damage the central nervous system, which can result in impaired cognitive and behavioral functioning similar to that described by Goddard. Alteration of photographs The paleontologist and science writer Stephen Jay Gould advanced the view that Goddard—or someone working with him—had retouched the photographs used in his book in order to make the "bad" Kallikaks appear more menacing. In older editions of the books, Gould said, it has become clearly evident that someone had drawn in darker, "crazier" looking eyes and menacing faces on the children and adults in the pictures. Gould argues that photographic reproduction in books was still then a very new art, and that audiences would not have been as keenly aware of photographic retouching, even on such a crude level. The 14 photos were subsequently studied further to show the nature of the retouching and subsequent use to help make Goddard's points. The psychologist R. E. Fancher, however, has claimed that retouching of faces of the sort which is apparent in Goddard's work was a common procedure at the time, in order to avoid a "washed out" look that was common to early photographic printing methods (poor halftones). Furthermore, Fancher argued, malicious editing on Goddard's part would take away from one of his primary claims: that only a trained eye can spot the moron in the crowd. Influence The overall effect of The Kallikak Family was to temporarily increase funding to institutions such as Goddard's, but these were not seen to be worthwhile solutions of the problem of "feeble-mindedness" (much less "rogue" "feeble-mindedness"—the threat of idiocy as a recessive trait), and more stringent methods, such as compulsory sterilization of people with intellectual disabilities, were undertaken. The term "Kallikak" became,
