If you think cold fusion has problems, you ain't seen nothing. Look at biology and social sciences (what my mother called "the hot air sciences"):
Psychology’s Replication Crisis Is Running Out of Excuses Another big project has found that only half of studies can be repeated. And this time, the usual explanations fall flat. https://www.theatlantic.com/science/archive/2018/11/psychologys-replication-crisis-real/576223/ Not only are they irreproducible, they are often dead wrong. See: A Waste of 1,000 Research Papers Decades of early research on the genetics of depression were built on nonexistent foundations. How did that happen? https://www.theatlantic.com/science/archive/2019/05/waste-1000-studies/589684/ I sometimes think many scientists reject cold fusion out of hand because they assume that most science is bullshit. Maybe because their own work is.
