The problem of motivation, not method. Both can use data, jargon, and peer review (see creation "science"). The core difference might be the attitude toward evidence: science seeks to test and potentially disprove its ideas; pseudoscience seeks to defend a preordained conclusion. The hard problem is that this is a psychological distinction about the practitioners, not a methodological one. You can't look at a paper and always tell. A bad scientist (cherry-picking data) is using pseudoscientific tactics, while a clever pseudoscientist can mimic the form of science perfectly. The line is blurred because it's about internal intent, which is invisible.
Example: Flat Earthers run experiments (lasers over water) they claim prove no curvature. Scientists point out flawed methodology. The Flat Earthers dismiss it as part of the conspiracy. The hard problem: Their process looks scientific—hypothesis, test, observation. The breakdown is their refusal to accept counter-evidence as valid. But who decides what "valid" counter-evidence is? The scientific community. So, in practice, science is defined by social consensus of what counts as proper evidence, not by a pure, objective rulebook. Pseudoscience is simply what that consensus excludes. Hard Problem of Science & Pseudoscience.

The notoriously difficult challenge of drawing a clean line between legitimate science and its fraudulent imitators. Where does physics end and metaphysics begin? When does speculative biology become pseudobiology? The problem is that science and pseudoscience exist on a spectrum, with no single magic criterion—falsifiability, peer review, empirical method—that perfectly separates them in all cases. Astrology is easy to dismiss, but what about string theory, which makes no testable predictions? What about Freudian psychology, which is culturally influential but methodologically dubious? The Hard Problem is that demarcation is itself a scientific and philosophical puzzle with no universally accepted solution.
Hard Problem of Science-Pseudoscience Demarcation "I know homeopathy is pseudoscience—it's water with memory or whatever. But is economics a science? It makes predictions, but they're always wrong. Is psychology? It studies minds, but can't agree on basic methods. The Hard Problem of Demarcation is why your 'just use common sense' approach doesn't actually work."
