How do the authors develop their analysis about the sentencing of black juvenile offenders? here’s the text:

Americans have accepted that juveniles are different from adults. Scientists confirm this, showing that there are significant differences in reasoning abilities, impulse control, and neurological development. Courts across the country have separate justice systems for most juvenile suspects, and in 2005 the Supreme Court said that even if tried as an adult, a juvenile cannot be sentenced to death.

Now the justices are again grappling with how to punish juveniles for serious crimes. For the second time in two years, they are poised to rule on the constitutionality of sentencing juveniles to life in prison with no possibility of parole.

But as our society has scrutinized1 this line between juvenile and adult, there has been little discussion of how race might influence people’s perceptions of juvenile status, despite widespread and substantial racial disparities in juvenile sentencing. Consider Florida, which is the state that had most often assigned juveniles life without parole2 sentences in cases other than homicide. As of 2009, 84% of the juvenile offenders who received this sentence were African American.

In our own work, we find that race can have a sweeping effect even when people consider the same crime. Prompting people to think of a single black (rather than white) juvenile offender leads them to express greater support for sentencing all juveniles to life without parole when they have committed serious, violent crimes. Thinking about a black juvenile offender also makes people imagine that juveniles are closer to adults in their blameworthiness. Remarkably, this was true for both people who were low in prejudice and those who were high in prejudice and for both liberals and conservatives.

[5]Thus, race has the power to dampen our desire to be merciful. This is why race must be considered in discussions about how we protect juveniles and what punishments are deemed appropriate for them. Though often overlooked, perhaps race is key to helping us understand people’s support for punitive3 policies more generally.
