  • "Corroboration"

    Popper stated that if a theory has survived many attempts to falsify, it is therefore “corroborated”. When we face decisions regarding which theory has the best practical application, it is rational to choose corroborated theories over the theories that are not corroborated (Godfrey-Smith, p.68)
  • "Confirmation is a Myth"

    "Confirmation is a Myth"
    All testing in science has the form of attempting to refute theories by means of observation. Popper stated it is never possible to confirm or establish a theory by showing its agreement with observation. The only thing observational test can do is to show that a theory is false (Godfrey-Smith, pp 58-59).
  • "Problem of Demarcation"

    "Problem of Demarcation"
    Karl Popper, sought to understand the difference between scientific theories and nonscientific theories (Godfrey-Smith, p.58). Particularly, distinguish science from “pseudo-science” as not all science receives equal achievement. Popper called the problem of distinguishing science from non-science “problem of demarcation”. Popper described the demarcation problem as the "key to most of the fundamental problems in philosophy of science (Popper 1962, 42).

  • "Scientific Change"

    "Scientific Change"
    Theory of scientific change, Popper proposed science changes via a two-step cycle that repeats endlessly. Stage 1. In the cycle is conjecture – a scientist will offer a hypothesis that might describe and explain some part of the world. Stage 2. In the cycle is attempted refutation – the hypothesis is subjected to critical testing, in an attempt to show that it is false (Godfrey-Smith, p. 61)
