Thanks for this important post and sharing your guidance!! This line of conversation and discussion is critical. Somewhere between evidence based medicine (EBM), evidence based public/social policy, and "good people with good intentions and lots of experience trying something based on theory" (my words), there HAS to be a new science that helps guide us with understudied but urgent issues like this. Help! I'm hoping others will chime in. Someone must have a (evidence based, studied??) framework for things like programs for elementary schools (Mind Up???), workplaces, positive parenting, etc.
