Microsoft has “taken action” to change its Bing search engine after it was found to give “horrifying” results for some terms.
Journalist Chris Hoffman discovered Bing suggested racist topics when he looked up words such as “Jews”, “Muslims” and “black people”.
Bing also ranked widely debunked conspiracy theories among the top suggestions for other words.
Mr Hoffman said Microsoft had to do better at moderating its search system.
In his investigation, Mr Hoffman looked up racially-themed terms and found that the majority of suggestions for further searches that accompanied results pointed people to racist sites or images.
Microsoft has always struggled with Bing search results not being right.
