This has never been the case across the history of humanity -- there has never existed a non-biased institution, and it's incredibly naive to think that a German think tank funded by the German government would be any exception.
"Level headed" and "sober" people are not immune to the effects of incentives and conflicts of interest. Researchers are dependent on grants, on invitations to conferences, etc., and so are liable to follow trends (tariffs bad), and p-hack to support the mainstream narrative (as they do in this analysis with P values > 0.01).
> German academia is actually full of sober, level-headed, nuanced people
Thanks for the laugh. I hope you realize how pretentious this sounds. In actuality, Germany's GDP is about 1/6th of that of the US, so these German academics don't sound very bright for how "level headed" and "sober" they are.
