Institutional Review Blog. Doing What Works - Psychology of Learning. Non-Academic Careers for Scientific Psychologists. This is a news website article about a scientific finding. In this paragraph I will state the main claim that the research makes, making appropriate use of "scare quotes" to ensure that it's clear that I have no opinion about this research whatsoever.
In this paragraph I will briefly (because no paragraph should be more than one line) state which existing scientific ideas this new research "challenges". If the research is about a potential cure, or a solution to a problem, this paragraph will describe how it will raise hopes for a group of sufferers or victims. This paragraph elaborates on the claim, adding weasel-words like "the scientists say" to shift responsibility for establishing the likely truth or accuracy of the research findings on to absolutely anybody else but me, the journalist.
