Not reliable. Popular science articles are unreliable, which is a typical manifestation of information dissemination distortion. In the past, taking mass media as the central node could build an effective bridge between experts and scholars and the public. Experts are responsible for conveying "first-hand information" and the media focus on expressing "grounding gas". Coupled with the screening and auditing mechanism in the editing process, the authenticity of the information can be guaranteed. In the decentralized self-media context, although everyone has a "megaphone", "truth" gradually gives way to "flow". For example, "blood test causes cancer" and "head change" which are widely circulated in the market literally mean communication.
