The Claim
On Chinese TikTok, the number of collections and shares of aortic dissection videos is not consistently associated with video quality, while the number of likes and comments is strongly inversely associated with video reliability.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
On Chinese TikTok, videos about aortic dissection that are saved or shared do not consistently match higher quality, but videos with more likes and comments tend to be less reliable.
See the scientific wording
On Chinese TikTok, the number of collections and shares of aortic dissection videos shows no consistent association with quality, while likes and comments are strongly inversely associated with reliability, suggesting that passive engagement (saving or sharing) reflects perceived utility, whereas active engagement (liking or commenting) reflects emotional arousal and sensationalism.
When people see dramatic or shocking health content, their brain triggers a strong emotional response that makes them react by liking or commenting. When people see useful or practical health information, they save or share it without reacting emotionally because they want to keep it for later use.
What the research says
1 studyOn Chinese TikTok, videos with lots of likes and comments tend to be less accurate, but videos that people save or share aren’t less reliable — meaning people react emotionally to flashy videos, but save useful ones.
