At one point I stated that she did not stay for questions. Across social media she insists that she did stay to answer questions. As usual, more clever spin that insulates a scienceless celeb from a science scholar.
A Question and Answer session means different things to different people.
To scientists it is a time to challenge claims, not tell fans where you bought the heels.
When I walked in I sat right by the floor microphone. I was going to get in line and ask as many critical questions as I could so students could see that she was an empty vessel in heels, making a buck through misinformation.
The session ended, everyone left, and there was no public Q&A.
I was disappointed and stood for a few minutes at the back of the auditorium until I ran into a faculty friend of mine. She could tell I was pissed. We talked for a few minutes and I looked back in, and Hari was talking to a group of maybe twelve students, taking pictures, etc.
This is her version of answering questions, independently confirmed by the following notes on social media:
She answered many questions?
One of her supporters didn't notice Q&A either.
Always Address Public Questions
In any of the thousand talks I've given in my career, the last line is "Thank you for listening, and I'd be happy to take any questions".
It is a time for the audience to dig deeper, to challenge my assertions, to talk about further evidence and set me right where I might be wrong. It is an important function of science communication.
I stay until the questions are answered. Last year in Colorado College the talk was from 7-8pm, but I stayed until almost midnight. At Vegan Chicago I lived through last call with some people skeptical about transgenic crop science. At the Orlando screening of GMO-OMG last year I answered questions until they kicked us out of the venue, then we went and got beers and kept on talking-- even though I had to leave Gainesville on a flight at 6 AM. If people have questions, you answer them. If they tell you that you are wrong, you learn and grow.
So did she answer questions from a handful of adoring fans? Probably.
Did she engage public defense of her claims? No.
And don't hold your breath waiting for it.
