Jewish Summer Camp

How do you best transmit your religious values to your children?  According to this Religion News Service article, sending your children to a Jewish summer camp might be one of the best ways to transmit Reform Jewish values.  Specifically, a survey conducted by the Reform Jewish movement:

...found that those who participated in overnight summer camps or immersive weekend-long getaways through the Reform youth movement were far more likely to be engaged in Jewish life in college and beyond and more committed to “doing good.”

Read the article and think about how attending a summer camp or weekend getaway would help in the transmission of religious values.  Do you believe the conclusion that attending a summer camp contributes to the transmission of values?

Note that the survey finds a statistical correlation.  It might be that the face-value interpretation -- namely, that attending a Jewish summer camp contributes to the transmission of Jewish values -- is correct. Yet, there is a second interpretation.  It might instead be that individuals who attend Jewish camps are not your average Reform Jews but are already committed to Jewish values.  So the correlation found in the study might merely reflect the alternative possibility that committed Jews are more likely to attend a Jewish summer camp, and that attending the camp does not actually enhance commitment.

Which interpretation do you think is correct?  Could both be true to a degree?
