In serious vein, science progresses by scientists having different opinions, then testing those against data.
Bluemoon, on the other hand, progresses by having an opinion, then entrenching it regardless of the data.
In the early stages of anything new, scientists and experts will have different opinions. A good way to judge whether they're reliable is if they acknowledge the uncertainty and refer to other possibilities.
You'll note since the first emergence of omicron, there are posters here who:
- assert their opinion as fact
- never offer a reference or link to the facts they claim
- insult and dismiss world experts.
Anyone who does any of this should be treated with extreme scepticism IMO
