According to internal communications and interviews with its researchers, Google took action this year to strengthen its control over its scientists’ papers by launching & quot; reviews of sensitive issues & quot;, and in at least three cases asked authors not to put their technology in a negative perspective. According to an internal web page explaining the policy, Google’s new censorship process requires researchers to consult their legal, policy and public relations teams before studying topics such as face and emotion analysis and the classification of race, gender or political affiliation. < / P > < p > Google said that technological progress and increasingly complex external environment are increasingly leading to moral, reputation, regulatory or legal issues arising from seemingly innocuous projects. Three current Google employees said the policy began in June. < / P > < p > eight current and former employees said the & quot; sensitive topics & quot; program added a round of review to Google’s standard paper review to prevent disclosure of trade secrets and other situations. For some projects, Google officials intervened at a later stage. According to an internal letter from Reuters, a senior Google manager, who evaluated a study of content recommendation technology shortly before its publication this summer, told authors to be very careful and to maintain a positive tone. A subsequent letter from a researcher to reviewers showed that the author updated the paper and removed all references to Google products. < / P > < p > four researchers, including senior scientist Margaret Mitchell, said they believe Google is starting to interfere with important research on potential technology hazards. “If we research the right things based on our expertise and Google doesn’t allow us to publish them for reasons that don’t conform to high-quality peer review, then we’re in a serious censorship situation,” Mitchell said < / P > < p > Google stated on its public facing website that its scientists have & quot; substantial & quot; freedom. This month, tensions between Google and some of its employees came to light after the sudden departure of scientist timnit gebru, who, together with Mitchell, led a 12 person team focusing on the ethical issues of artificial intelligence software. Gebru said Google fired her because she questioned an order banning the publication of research. The study claims that artificial intelligence that mimics speech may be bad for marginalized people. Google accepted and accelerated her resignation at the time. It’s not clear whether timnit gebru’s paper has been censored by Google for “sensitive topics.”. Global Tech
