I want to know the answer to the following question:
What kind of criteria frequently used in science complicates the definitiveness of some hypotheses' falsification?
All the background I'm provided with is that "Rather than offering a set of instructions that merely need to be followed diligently to achieve science, Popper makes it clear in The Logic of Scientific Discovery that his belief is that the resolution of conflicts between hypotheses and observations can only be a matter of the collective judgment of scientists, in each individual case.". Is that enough to answer the question?
Answer: no
