This thread has had a huge influx of comments from new accounts in the last 24 hours—over 250 and counting. They are all, I think, critical of the study. Many have been unsubstantive, but many have had interesting things to say.
Normally we'd consider closing the thread in a case like this, to prevent it from being brigaded. But this is an unusual case and I'm curious to see how far it goes.
In case any of the new commenters happens to read this: I'm the lead moderator of Hacker News. Would you mind sharing with us how you found out about this discussion? It's unusual for us to see so much activity in a thread that is already several days old, and I'm curious to find out what happened.
