Weingart started early to examine the production of knowledge and its interaction with politics and the media. His book Wissen Beraten Entscheiden described forms of science advice to politics in Germany. He wrote as well a book about the science base for the German eugenics studies and their interaction with Racial hygiene policy. For the present, Weingart states a higher importance of PR agencies intermediating between science and public and saw a trend of a more 'public science' within a postindustrial information society. The media's role as the fourth estate increases and influences science findings already in its production state. It may be attractive for some scientists to use their celebrity status in the media as means of gaining acceptance for their findings or for their preferred fields of study. Such celebrity bonuses however weaken peer review controlling mechanisms. Weingart saw the hype about of Daniel Goldhagen's books in Germany as such an example. Weingart also took the climate change debate as an example where the public announcement of findings may backfire. The public debate about climate change in Germany was at its height around 1986, when the energy committee of the Deutsche Physikalische Gesellschaft predicted a climate catastrophy rendering earth a dead planet within 50 years. The scientists asked in parallel to increase nuclear power stations to reduce CO2 emissions. When meteorologists started to criticize the alarmist tone, the AKE toned down its conclusions to climate change instead of climate disaster. However the public scene kept using the alarmist conclusions first and later on doubted scientists overall credibility on the topic. Weingart prefers science communication to provide proof of uncertainties and ignorance combined with established facts. The basic aspects of "Verwissenschaftlichung der Gesellschaft – Politisierung der Wissenschaft" go hand in hand.
