Someone tried to study the effects of porn on men’s perception of women (link) and could not find men who had never watched porn to form a control group.

Yet the researcher still feel comfortable concluding:

All test subjects said they supported gender equality and felt victimized by rhetoric demonizing pornography. "Pornography hasn't changed their perception of women or their relationship which they all want as harmonious and fulfilling as possible. Those who could not live out their fantasy in real life with their partner simply set aside the fantasy. The fantasy is broken in the real world and men don't want their partner to look like a porn star," says Lajeunesse.

Wow! How scientific! It’s okay guys, they say porn doesn’t affect them.

Also good job to the researcher for finding a way to get the Madonna-whore complex in there too.

Edit: just realized this study is old, why someone on my Facebook felt the need to share a 12 year old study? Who knows 🤷🏼‍♀️
