The hunter vs. farmer theory is applied to attention-deficit hyperactivity disorder (ADD or ADHD) and adult attention-deficit disorder (AADD). The theory was first proposed by Tom Hartmann, who worked with children with ADD. The premise is that ADD attributes in only some humans may be a a result of a form of adaptive behavior. Under this theory, as civilized society evolved, the attributes of a hunter gave way to those of a farmer for most people as society evolved from a nomadic existence to one of more permanent settlements. Over many years, most humans changed genetically, but some (those with ADD) still have the older hunter characteristics.
While the cause(s) of ADD/ADHD in humans are not known, and continue to be the subject of considerable research, Tom Hartmann's work has also pointed to the hyperfocus aspect of ADD as a gift for many persons, a position shared by many other medical and counseling professionals.
In the hunter-gatherer cultures that preceded farming societies, hunters (presumably mostly men) probably needed hyperfocus more than gatherers (presumably mostly women). This may be connected with the fact that ADHD is diagnosed in twice as many boys as girls.
It should be understood that this hypothesis is only one of several that attempt to account for the origins of ADHD. A major competitor, probably more widely accepted, is that ADHD is merely the co-occurrence of several genetic variants. Harpending and Cochran (PNAS, Jan 8 2002) offer a 3-phase view of history that includes hunter-gathering; female farming; and then intensive agriculture; they suggest that ADHD increased reproductive fitness in the second phase. An important view, with considerable genetic backing, is that some of these genetic variants may have value in certain kinds of social groups, such as those that have migrated (Chang et al 1996 Human Genetics 98; Grady et al 2003 Molecular Psychiatry 8).
