Correlations on porn

From Garth Zietsman:

Firstly (using the General Social Survey) I found no relationship between being pro the legality of porn, or propensity to watch porn, and pro social behaviors e.g. volunteer work, blood donation, etc.

We can dismiss the feminist (and sociological) charges of porn increasing sexual violence and leading to sexism. The USA, Sweden, Germany, Netherlands (2) and Japan were just some of the countries that suddenly went from no legal pornography to quite widespread availability and consumption of it. These studies all found that greater availability of, and exposure to, pornography does not increase the rate of sexual assaults on women, and probably decreases it (3). Japanese porn is quite frequently violent and yet even there rape decreased from an already very low base. It’s interesting that an increase in porn exposure decreases sexual violence only, and has no effect on other crime. Economists would put this down to a substitution effect.

Several countries have sex offender registers – mainly of pedophiles. A wide variety of professions are represented on these registers. Members of professions that supposedly promote morality e.g. clerics or teachers, are quite common on it yet conspicuously absent from such registers are men who have worked in the porn industry.

This study (1) found no relationship between the frequency of x-rated film viewing and attitudes toward women or feminism. From the GSS (controlling for IQ, education, income, age, race and ideology) I found that those who are pro the legality of porn are less likely to support traditional female roles, more likely to be against preferential treatment of either gender, and to find woman’s rights issues more frequently salient. Although I found that women’s rights issues are less salient to male watchers, and female watchers are less likely to think women should work, I also found that watching porn is unrelated to negative attitudes toward women and feminism.

In short exposure to and tolerance of pornography does not cause anti-social behavior (and may even reduce it in relation to sex) and does not get in the way of pro social behavior either.

The sociological and religious charge that pornography undermines monogamy and family values does however receive support. From GSS (and controlling for IQ, education, income, age, race and ideology) I found that men who are pro legalizing porn are less likely to marry and are more pro cohabitation. There was no such association for women. A higher propensity to watch porn movies is also associated with a lesser likelihood of marrying but is unrelated to cohabitation attitudes – in both men and women. So a pro porn attitude is consistent with a reduced respect for marriage.

Both genders also tend to have fewer kids in marriage, if they are pro the legalizing of porn. However, for men, a higher propensity to watch porn movies is associated with having MORE children within marriage. Note that pro legal porn attitudes and porn movie viewership is not associated with having children out of wedlock – for men its associated with a lower chance of that happening – so porn doesn’t lead to that kind of irresponsible behavior.

Possibly part of this general pattern, I found that both being pro the legality of porn and watching porn are related to lower voting rates in general elections.

I found no relationship to a variety of ‘family values’ type questions e.g. importance of family, or to the value of relationships and friendship.

Being pro the legality of porn, and porn viewing, are associated with unhappiness with the family or marriage – especially for men. Those who are pro porn also tend to have a greater number of sexual partners and are more likely to have a sexual affair. This supports the 1984 and 1988 discoveries of Dolf Zillman and Jennings Bryant (4) that the effects of repeated exposure to standard, non-violent, commonly available pornography includes: increased callousness toward women; distorted perceptions about sexuality; devaluation of the importance of monogamy; decreased satisfaction with partner’s sexual performance, affection, and appearance; doubts about the value of marriage; and decreased desire to have children. Later research studies further confirm their findings.
