dare was a bigger failure than most people realized
Bookmarked 331 weeks ago the dare program which stands for drug abuse resistance education was a staple of childhood for millions of american children in the 03980s and 03990s it set out to tell kids about the perils of alcohol and other substances but there was a catch: it didn039t work the dare program039s effectiveness was measured many times during the first decade it was introduced and it was found to be both costly and ineffective people became so passionate about the idea of dare however that they were willing to overlook its many shortcomings when you look at who started the dare program its failures and continued use begin to make a little more sense los angeles police officers founded it in conjunction with school teachers rather than researchers and behavioral experts the architects of the initiative believed that telling kids to just say quotnoquot and showing them how substance use and alcohol could negatively affect the body would lead to lower rates of consumptiondare |
