You can view what Google “knows” about you on your account settings. I made my account when I was very young, I lied about my age and my gender, then it made assumptions based on my interests of my professional situation. I guess many people in my gender and age group, sharing my actual interests (tech, movies, culture, food) are also interested in the kind of content you described (Joe Rogan, Jordan Peterson, Yiannopolous, etc). I keep clicking “not interested”, but the algorithm keep suggesting these videos to me. I don’t mind that Google doesn’t know my politics. I’m a feminist, but there’s really not a lot of interesting discourse about feminism on Youtube, so I just read and attend real life lectures instead.
