tcd004 writes "The PBS NewsHour reports that German researchers analyzed 500,000 text messages sent on Sept. 11, 2001, and created an hour-by-hour psychological profile Americans on that day. The pager text messages, which were posted to Wikileaks in 2009, were analyzed for words that correlated to sadness, anxiety and anger. The results show that words related to anger dominated communications as the day wore on. The study was published in the Journal of Psychological Science."
