It’s always interesting to see which data analysis or surveys get covered by mainstream media outlets and which don’t. A bunch of media outlets chose to highlight a study this week comparing 289 teens (average age of 17 in 1996) who took abstinence pledges at that time with 645 teens who were otherwise similar but didn’t take abstinence pledges. That is, the two groups shared, among other things, similar religious, sexual and political views. The study did not in any way compare either of these groups with the 11,000 or so teens from the same data set who didn’t take pledges and weren’t similar in their political views or religious views.
