The context of discovery relates to the initial formulation of hypotheses, often involving creativity and speculation, which does not necessarily adhere to strict scientific methodology. In contrast, the context of justification concerns the methods used to support or falsify these hypotheses. Understanding these two contexts is crucial for the demarcation problem because it highlights that not all stages of scientific inquiry involve the same level of empirical rigour. While pseudoscience may focus more on the unregulated context of discovery without sufficient justification, science demands rigorous and empirical methods of justification for its claims.

The demarcation problem can significantly affect public perception of science because it influences what is accepted as legitimate scientific knowledge. When pseudoscientific claims are mistaken for science, they can erode public trust in scientific institutions and experts, especially if such claims are later discredited. Moreover, the inability to effectively demarcate science from non-science can lead to confusion about the reliability and authority of scientific information. This makes it imperative for education and public communication of science to clearly distinguish between well-supported scientific theories and pseudoscientific or non-scientific claims.

Peer review and replication are essential processes in reinforcing the scientific method's self-correcting nature, which is a key factor in demarcating science from pseudoscience. Peer review ensures that scientific research is critically evaluated by experts in the field before it is published, providing a check against unfounded claims and methodological flaws. Replication serves as a means of verifying scientific results by repeating experiments or studies to see if the same conclusions can be reached. These mechanisms help maintain scientific standards, promote accountability, and distinguish scientific research from pseudoscience, which often lacks such rigorous scrutiny.

The principle of parsimony, often referred to as Occam's razor, suggests that among competing hypotheses, the one with the fewest assumptions should be selected. In the demarcation of science from pseudoscience, this principle is instrumental because scientific theories typically strive for simplicity, providing the most straightforward explanation that aligns with the evidence. Pseudoscientific theories, however, often invoke more complex or ad hoc hypotheses that cannot be empirically tested. By favouring simplicity and testability, the principle of parsimony helps to filter out explanations that do not meet the standards of scientific rigour.

The problem of induction posits that no amount of empirical data can conclusively verify a scientific theory; it can only increase its degree of probability. This presents a challenge for demarcation, as scientific theories cannot be definitively proven to be true in the same way they can be proven false, according to Popper's criterion. Consequently, the demarcation between science and pseudoscience becomes less about absolute verification and more about the systematic and rigorous approach that science takes in forming theories and testing hypotheses. This contrasts with pseudoscience, which often lacks this rigorous methodology and does not seriously engage with potential refutations.
