Similarly, psychologists have found that male subjects, immediately after watching pornography, are more likely to express misogynistic attitudes. But as professor Kendall points out, we need to be clear on what those experiments are testing: They are testing the effects of watching pornography in a controlled laboratory setting under the eyes of a researcher. The experience of viewing porn on the Internet, in the privacy of one's own room, typically culminates in a slightly messier but far more satisfying experience—an experience that could plausibly tamp down some of the same aggressions that the pornus interruptus of the laboratory tends to stir up.
In other words, if you want to understand the effects of on-screen sex and violence outside the laboratory, psych experiments don't tell you very much. Sooner or later, you've got to look at the data.
