On Thursday, December 16, 2021, TikTok announced an algorithm change.
TikTok changes algorithm to 'do not show the same video to users over and over' | GIGAZINE.BIZ
TikTok's algorithm change is 'to prevent users from seeing the same type of video multiple times'. TikTok explains why the change is 'because content about'loneliness'and'radical diets' is repeatedly displayed to teenage girls, which has a negative impact on health.'
On Friday, the day after TikTok announced, the Wall Street Journal said, ''The Corpse Bride Diet': How TikTok Inundates Teens With Eating-Disorder Videos. Did you make the girl soaked in a video of eating disorders?) ”Was published. In the article, I can not stop watching the radical diet video that is flowing on TikTok, and the record of the girls who were hospitalized and the experiment of how TikTok actually showed the video to the girls. The result is described.
The Wall Street Journal has created 100 TikTok accounts over the past year and made them watch various videos as bots. It is said that 'interests / interests' were set for these accounts using keywords and machine learning.
The bot watched when his keyword and the content of the video matched, and when it did not match, he passed through the video and moved on to the next. In addition, some bots searched at the first stage and sent signals indicating their own tastes. Some bots were programmed to be '13 years old' and focused on topics such as weight loss, gambling, and drinking, and were allowed to watch these videos 255,000 times.
Analysis by The Wall Street Journal first revealed that there are 32,700 videos in TikTok that match hundreds of keywords related to weight loss. Of these, 11,615 videos matched keywords related to eating disorders, and 4402 videos justified or recommended eating disorders. We also found that many of the videos were tagged with unusual spellings to avoid moderation.
In addition, the Wall Street Journal also reports on teenage girls who actually had excessive dietary restrictions due to TikTok, lost their hair due to protein deficiency, developed gallstones and had surgery to remove the gallbladder. Mentioned.
The Wall Street Journal reported to TikTok about 2960 eating disorder videos found in the survey, of which 1778 were removed from TikTok. Also, TikTok announced the algorithm changes a few days after the Wall Street Journal reported the investigation to TikTok and asked for comments.
It is said that SNS tends to give a negative body image to teenage boys and girls, and it has been pointed out that it adversely affects mental health.

Instagram has been particularly badly pointed out, but TikTok has a similar problem. In the United States, it is said that the epidemic of the new coronavirus infection (COVID-19) has increased the eating disorders of young people, and experts say that children who cannot go out are isolated and spend more time on SNS. I think it was the cause.
