Is Melissa tackling the work? > >I think we should both speak up during the review about our concerns. Dr. Kristin Shay Hendrix (8/10/2020 07:04:21 PDT): >OK just read it. I'm concerned about the plan they put forth. We did design a survey to dig into teens attitudes (that was part of the study we'd presented to Schultz et al.). I do not think we should study only teens, so this proposal gives me strong pause.

Roberto Medri (8/10/2020 07:05:20 PDT): >There are zero details on the test Roberto Medri (8/10/2020 07:05:51 PDT): >It's a "come on let's ship this" deck Dr. Kristin Shay Hendrix (8/10/2020 07:09:46 PDT): >Totally. The teens findings were very, very concerning, though. So I want to do this right and not screw it up. Dr. Kristin Shay Hendrix (8/10/2020 07:10:00 PDT): >It was a pretty controversial/contentious Zuck review with Adam and Fidji not being in alignment. Roberto Medri (8/10/2020 07:10:14 PDT): >And this is still true Dr. Kristin Shay Hendrix (8/10/2020 07:10:15 PDT): >And Schultz was as diplomatic as he possibly could be knowing that all of this was not handled well. Dr. Kristin Shay Hendrix (8/10/2020 07:10:24 PDT): >Agree Definitely still true.

Dr. Kristin Shay Hendrix (8/10/2020 07:11:50 PDT): >Interesting Moira Burke in CDS has HUGELY pushed for Daisy to ship. Dr. Kristin Shay Hendrix (8/10/2020 07:12:00 PDT): >It actually caused a lot of thrash at the last minute. Roberto Medri (8/10/2020 07:12:09 PDT): >I'm not surprised Dr. Kristin Shay Hendrix (8/10/2020 07:12:11 PDT): >Because she was having convos with leadership that those working on Daisy weren't a part of. Roberto Medri (8/10/2020 07:12:54 PDT): >What bothers me is everyone seems more motivated by incentives Dr. Kristin Shay Hendrix (8/10/2020 07:12:58 PDT): >I really appreciate and respect Moira's expertise. However, not aligning with myself and the FB Res Dir was really thrashy. And Schultz was not thrilled. Roberto Medri (8/10/2020 07:13:03 PDT): >Than by evidence Dr. Kristin Shay Hendrix (8/10/2020 07:13:08 PDT): >Totally agree.
