Probably the most egregious use of this fallacy in recent times was in selling the public on the mRNA vaccines against COVID-19. These had not been tried on such a wide scale, and doing so was, IMHO, scientifically irresponsible. At the time I was suspicious of this and stuck with a more traditional adenovirus vaccine (J&J) which itself had been trashed by its competitors.
That suspicion, in turn, was based on experience both in my usual profession and with computers. Just because something is the “latest and the greatest” doesn’t mean it’s the best. But that was the way these vaccines were sold to the public.
In the end, I think this will have long-term effects on people that are only now being realised.
