One of the falsehoods that has been stuffed into your brain and pounded into place is that moral knowledge progresses inevitably, such that later generations are morally and intellectually superior to earlier generations, and that the older the source the more morally suspect that source is. There is a term for that. It is called chronological snobbery. Or, to use a term that you might understand more easily, “ageism.”
Whether experts or amateurs, most of us have a tendency to be quite dogmatic about so-called scientific facts. Since news writers are not immune from this tendency, news stories based on scientific assumptions should be read or viewed with some skepticism.
Don't be trapped by dogma — which is living with the results of other people's thinking.
