Because they have already been discredited a long time ago for lying and have lost all credibility in the scientific community.@JohnDB
Im just wondering... Why would these scientists and doctors make up these conspiracy theories?
Such people are actually loosing for expressing different opinions, not gaining. So what is their motivation?
The research field is cutthroat. Highly competitive as well. Ideas are stolen. Credit is stolen too. Seen it happen to researchers that are friends of mine. But the truly novel and unique thinkers continue to learn, grow, and gain more ideas...and continue in the limelight. The thieves get eventually outed. They get slammed and shunned. People refuse to work with them when their egos get too big and it affects their work and those who they work with. (Happens often in the PHD world)
So all the research money that funds their salaries dries up...they have nothing left to investigate nor anyone willing to work with them. (Research doesn't happen in a vacuum)
So these discredited guys make a 5 minute video to try to get back into the limelight and world of credibility for unsuspecting people.
Because after all the decades of education their ego is going to make them unemployed and unemployable. So they figure it couldn't hurt to try. And as a result we have people believing in HCQ, magnetic fields, and 5G causing or curing Covid. And those who are nothing more than click bait artists promoting fake science. And the people who first promoted the HCQ got nothing from the USA but did get a small grant from the WHO against the advice of the reputable doctors in the WHO. (I know some of them too)
Meanwhile, back in the world of reputable science... unheralded and diligent the real honest guys were crafting the Vaccines and isolating the specific antibodies needed and the spike proteins on the coronavirus.
Trying for real to put an end to this pandemic.
Also trying to find a real Antiviral medicine for it.
