Marine Biology. Specifically marine mammal proliferation/reproduction. I don't know specifically why they are so inaccurate. Probably because they are dry algorithms based on past data. Many in this field are in severe denial and keep cranking out new models that better serve them and their dogma. They don't admit they were wrong (which is okay to a point in research) but many rely so heavily on funding that finds results that support the narrative and these models are easiest to serve that end. There comes a time to move on and be honest w/what you are really trying to accomplish....
