At the time I loved doing it. Then I didn’t want to do it anymore, but I couldn’t stop. The clothes in my closet hung exactly two fingers apart.… I made a ritual of touching the wall in my bedroom before I went out because something bad would happen if I didn’t do it the right way. I had a constant anxiety about it as a kid, and it made me think for the first time that I might be nuts.”  Marc, diagnosed with obsessive-compulsive disorder (from Summers, 1996)

87. Figure 14.10Figure 14.10 Cold-blooded arousability and risk of crime Levels of the stress hormone adrenaline were measured in two groups of 13-year-old Swedish boys. In both stressful and non-stressful situations, those later convicted of a crime (as 18- to 26- year-olds) showed relatively low arousal. (From Magnusson, 1990.)

88.  PET scans of 41 murderers showed reduced activity in their frontal loves and repeat offenders had 11% less frontal lobe tissue than normal

89. “Perhaps a biologically based fearlessness, as well as early environment, helps explain the reunion of long-separated sisters Joyce Lott, 27, and Mary Jones, 29—in a South Carolina prison where both were sent on drug charges. After a newspaper story about their reunion, their long- lost half-brother Frank Strickland called. He explained it would be a while before he could come see them—because he, too, was in jail, on drug, burglary, and larceny charges (Shepherd et al., 1990). According to a 2004 U.S. Justice Department report, 48 percent of 2 million state prison inmates say they have had incarcerated relatives (Johnson, 2008).”

90. Figure 14.12Figure 14.12 Biopsychosoci al roots of crime Danish male babies whose backgrounds were marked both by obstetrical complications and social stresses associated with poverty were twice as likely to be criminal offenders by ages 20 to 22 as those in either the biological or social risk groups.

Their conclusion: There is virtually no evidence of “moon madness.” Nor does lunar phase correlate with suicides, assaults, emergency room visits, or traffic disasters (Martin et al., 1992; Raison et al., 1999).
