Violent behavior in context: Tucson and beyond

Jared Lee Loughner, caught at the scene of the attempted assassination of Congresswoman Gabrielle Giffords and the murder of six other people, has been repeatedly described as crazy, a nutbag, disturbed, and mentally ill—labels that put the blame for the violence on him as another “sole gunman” who has committed a heinous act.

But heinous acts take place within contexts, and Loughner grew up within contexts where the spreading of hate and calls for violence against various groups have become rampant.

To understand fully the factors that contributed to the violence in Tucson and similar incidents, one must do an ecological analysis.

As described in our post on August 23, 2010, an ecological analysis assumes that the character and behavior of adult humans are shaped by forces at different levels:

  • The individual level (e.g., genetic predispositions, brain functioning)
  • The microsystem level (primarily the family)
  • The exosystem (e.g., the neighborhood)
  • The macrosystem (broad cultural values and mores)

Also important is the chronosystem, which focuses on changes in the individual’s environments over time that may affect his or her development.

In today’s post and the following ones, we examine how factors at each level could have contributed to Jared Lee Loughner’s attack on Congresswoman Giffords and others.

At the individual level, there is considerable evidence that Loughner may suffer from some sort of mental illness. There are also many reports that he abused drugs. Far too many people suffer from severe psychological symptoms, and far too many abuse drugs, but the vast majority of these people do not try to kill other human beings.

What other factors may have contributed to Loughner’s deadly behavior? We will return to this question in our next two posts.
