"A new nationwide study of anonymised credit-card receipts from a major online adult entertainment provider finds little variation in consumption between states."
You’re right. I had to pare it down to 300 words and thought that was encompassed in this: “”When it comes to adult entertainment, it seems people are more the same than different,” says Benjamin Edelman at Harvard Business School.” I also thought the mention about very little variation at the end got that point across without misconstruing the meaning of the article.
