The names of 191 individuals and 43 organizations were submitted to the Norweigan [sic] Nobel Committee for consideration. Every year, the five-member Committee sends out thousands of letters to qualified individuals — lawmakers, university professors and other figures involved in the public sphere — calling for nominations. The lists of nominees are kept secret for 50 years, but some voting individuals choose to announce their nominations publicly.
This seems as good a process as any. Lawmakers tend to have ideological agendas, but there seems to be plenty of room for other opinions. The irony is that how the Nobel Committee makes a decision about Manning will probably have a lot to do with how his trial proceeds. In other words the very government that has chosen to prosecute him may become a major data source when the Nobel Committee ponders what decision to make.
