Regarding punishment, we've learned from the downfall of Harvey Weinstein and other famous men not only that times have changed, but also that ostracism is an efficient tool. It reminds me of the tradition of bathroom lists of sexual assaulters at Brown beginning in 1990. Back then the administrators called the students who wrote them "magic marker terrorists" and threatened them with expulsion if caught. Now a Shitty Media Men list can dominate the news for days as HR departments across the coasts hastily assess their employees and their liability.

After studying dozens of sexual assault cases, it is clear to me that the "he said/she said" aspect is a big part of what makes them fraught. Many experts agree with this. But that same fraught nature is reflected in both legal standards of consent and philosophical theories of consent.

An interesting reversal is happening right now. The college women who kicked all this off have been superseded in the mainstream media by celebrities like Gwyneth Paltrow and Angelina Jolie. And now a new group of college women - the ones in college now - are looking at Paltrow and Jolie as models for the appropriate way of dealing with sexual predators.

Let's reach the students who will abide by a "yes means yes" standard in sexual behavior and reeducate them to use it. And as more and more of them use it, others will adopt it too. We're on our way to a new social norm and that's a beautiful thing.

As Americans, we do love punishment.

Harvey Weinstein is a monster. And what campus victims are talking about has a lot more gray in it - many more complexities.

I don't think we get the degree to which technological mediums like Snapchat and Instagram are also changing our relationships. I think we will learn down the line that they have created profound changes in our social and sexual lives.
