... Scientists do not try to shut down discussion or debate with "the science is settled", shut up. Scientists do not use the argument that 97%* of us are in consensus, don't you want to be one of the cool kids?
Interestingly enough, those guilty of this (and their apologists) are the most likely to be found proclaiming "Science!" and appealing to authority or popularity as they continue to do it. Those who might otherwise be considered scientists are stepping outside of and neglecting that role when they do so.
The scientists may be in it for truth, or they may be in it for a political agenda. The elites are the ones looking to profit explicitly, or at least knock our freedom down a notch or two, so they recruit the scientists. Follow the money...
Yep, no shortage of academics willing to rubber stamp a conclusion if it benefits them in any way.
