Both higher divorce rates and the Women's Movement are the by-product of long-term changes in the socio-economic and technological structure of North America. Yet, the new feminist wave is often accused by the public of having played a role in the recent upsurge in divorce rates. Herein, the validity of this popularly-held belief is explored indirectly. Separated/divorced women were asked about their current beliefs in the Women's Movement; then, they estimated the strength of these beliefs during the past two years of their marriage. A matched control group of still-married women was included. The key finding of this study is that the separated/divorced women's reported level of agreement with the goals of the Women's Movement was lower during their last two years of marriage and had increased substantially after they had separated. The second and complementary result is that the still-married women in the control group showed no time-related average difference, therefore precluding time or aging as explanatory variables for the first results. Divorce is described as an ideologically radicalizing experience for women, especially at the higher socioeconomic level. In contradiction with certain popularly-held beliefs, our results indicate that gender roles liberation follows divorce.
