Coming after the David Shor firing (for tweeting Omar Wasow study), the message this letter sends to young scholars is: do not forward or cite studies whose conclusions challenge dominant views. Play it safe.

If scholars scan each others' collective work—every word written or recorded—searching for the least charitable reading of every snippet, we can all destroy each other.

There was once a time when academics thought it was good to question orthodoxies. In recent years, expressing contrary views has become more dangerous.
