Google fires Ethical AI lead Margaret Mitchell

Google fired Margaret Mitchell, lead of the Ethical AI team today. The move comes just hours after Google announced diversity policy changes and an apology from Google AI chief Jeff Dean in the wake of the firing of former Google AI ethics lead Timnit Gebru in late 2020.

Mitchell, a staff research scientist and Google employee since 2016, had been under an internal investigation by Google for five weeks. In an email sent to Google shortly before Mitchell was placed on investigation, Mitchell called Google firing Gebru “forever after a really, really, really terrible decision.”

A statement from a Google spokesperson about Mitchell reads: “After conducting a review of this manager’s conduct, we confirmed that there were multiple violations of our code of conduct, as well as of our security policies, which included the exfiltration of confidential business-sensitive documents and private data of other employees.”

Mitchell was a member of the recently formed Alphabet Workers Union. Timnit Gebru has previously suggested that union protection could be a way for AI researchers to protect themselves from retaliation like the kind she encountered when a research paper was reviewed last year.

Earlier today, Google AI chief Jeff Dean apologized if Black and female employees were hurt by the firing of former Google AI ethics lead Timnit Gebru. Additional changes to Google diversity policy were also announced today include tying DEI goals to performance evaluations for employees at the VP level and above.

On Thursday, Google restructured its AI ethics efforts that brings 10 teams within Google Research including the Ethical AI team under Google VP Marian Croak. Croak will report directly to Jeff Dean. In a video message, Croak called for more “diplomatic” conversations when addressing ways AI can harm people.

“Marian is a highly accomplished trailblazing scientist that I had admired and even confided in. It’s incredibly hurtful to see her legitimizing what Jeff Dean and his subordinates have done to me and my team,” Gebru told VentureBeat about the decision Thursday.

Mitchell and Gebru came together to colead the Ethical AI team in 2018, eventually creating what’s believed to be one of the most diverse divisions within Google Research. The Ethical AI team has published research for models cards to bring transparency to AI and how to perform internal algorithm audits.

The way Gebru was fired led to allegations of gaslighting, racism, and retaliation led to questions from thousands of Google employees and members of Congress with records of authoring legislation to regulate algorithms. Members of the Ethical AI team requested Google leadership take a series of steps to restore trust.

A Google spokesperson told VentureBeat that the Google legal team worked with outside counsel to conduct an investigation. A Google spokesperson did not provide details when asked what steps the organization has taken to meet demands to restore trust made by the Ethical AI team or laid out in a letter signed by more than 2,000 employees shortly after the firing of Timnit Gebru that called for a transparent investigation in full view of the public.
