RT Journal Article SR Electronic T1 Integrated Incentives for Fertility Control JF Science JO Science FD American Association for the Advancement of Science SP 1278 OP 1283 DO 10.1126/science.169.3952.1278 VO 169 IS 3952 A1 Kangas, Lenni W. YR 1970 UL http://science.sciencemag.org/content/169/3952/1278.abstract AB Incentive proposals for fertility control have stimulated considerable debate and only narrowly conceived trials. As a result, there exists a tendency to dismiss almost offhandedly the entire concept of using material incentives to further contraceptive practice before any have been adequately tried. Moreover, a majority of proposals thus far have been characterized by a search to uncover the "one best way" to circumvent the myriad frustrations encountered in attempting to reduce birthrates in traditional societies.
