> Doesn't science build off other science? When one scientist takes the conclusion of another study for granted (Example that X drug is effective), and then tries to build off of it with their own study (testing if A or B delivery method is more effective), doesn't it become obvious fairly quickly the second study is based on a bad conclusion of the first study? Indeed. In fact, this is extremely common in biology. It’s possible that some fields need to confront the replication crisis (psychology, for example, is frequently cited and the subject of the OP), but I really don’t see this in my field.
