Second point you should think carefully about: although it’s true as you say that scientists look very carefully at their work, THEY ARE JUST AS SUSCEPTIBLE TO MORAL CORRUPTION AS ANY HUMAN BEING.
All it takes for scientists to either look the other way or to perpetrate malevolent acts is an envelope of cash, the electronic funding of an account, blackmail or other coercion.
And here’s a challenge to your assertion about the intelligence of scientists: how many of them believe in communism? Or globalism? Belief in the viability or preeminence of either of these political fallacies is an intellectual deficit.
I never said they aren't. There are plenty of examples of scientists manipulating data, fabricating data, plagiarizing, etc., to advance their own careers.
But that is rather outside of the current discussion, which is whether the Wuhan virology laboratory could invent a human pathogen (highly unlikely with current technology) and furthermore, to disseminate it without anyone noticing that it was artificially created. No, the signs of artificial manipulation of a pathogen would be as obvious to an expert as the signs of Photoshop manipulation of a photo.
