I have degrees in science and engineering, and have worked for many decades as both.
For an engineer to keep his job, he has to be brutally correct and honest – all the time. Products and reality don’t lie.
For a scientist to keep his job, he has to obtain funding. This is generally accomplished by convincing politicians that something you want to study is important, and frequently involves exaggeration and/or fabrication.
This is what happens when engineers don’t do their jobs correctly.
