This video discusses the philosophy of science, including the idea that science is not about certainty, but about doubt and the need for explanations that are mechanistic. It also discusses the ancient Greeks, who were known for their development of science. The video covers the work of philosopher Karl Popper, who developed the theory of falsificationism, and philosopher Imre Lakatos, whose theory of scientific inquiry emphasizes the growth and evolution of scientific ideas.

00:05:00 This video discusses the work of philosopher Karl Popper, who developed the theory of falsificationism, and philosopher Imre Lakatos, whose theory of scientific inquiry emphasizes the growth and evolution of scientific ideas. The video also covers the development of democracy in Greece, and the importance of criticism in science. Finally, the video points out the importance of political systems in fostering the growth of scientific knowledge.
00:10:00 Philosopher of science, Popper, argued that scientific theories should be based on empirical evidence, not authority. He also claimed that the process of induction, or drawing general conclusions from a few observations, is not a logical one. Freud, on the other hand, claimed that whatever is observed in life is subject to the observer's biases and desires.
00:15:00 Philosophy of Science: Popper and Lakatos discusses the difference between science and one science, and how in either case, a general claim must be based on observations. Popper argues that in one case, a theory can be shown to be false, and in the other case, the theory can never be proven false. He goes on to say that the essence of science is falsifiability, and that in order to learn from experience, a theory must be put to the test. Lakatos points out that although Popper captured the basic idea of falsifiability, his statements are actually different ways of saying the same thing.
00:20:00 This video discusses the philosophy of science and how it can be used to evaluate theories. The two main points made are that a theory that forbids many outcomes is easy to understand, but it doesn't explain anything, and that a theory that allows many outcomes is better because it is more likely to be correct.
00:25:00 In this video, philosopher of science, Popper, and Lakatos are discussed. Popper argues that theories are not based on personal opinion, but on observation and logic. Lakatos believes that scientific theories are never certain, and that scientists should be open to criticism in order to grow their knowledge. These principles are discussed in the context of current professional ethics for scientists. It is noted that these principles are not always followed, but that the trend is moving in the right direction.
00:30:00 Popper and Lakatos argue that all scientific theories are provisional, and must be tested to see if they are true. If a theory is not testable, it is not a scientific theory, and cannot be used to make predictions or explanations.
00:35:00 In this video, Dr. Steven Novella discusses the criterion of falsifiability, which is used to determine whether a theory is substantial. He also provides an example of a substantial theory in the context of evolutionary psychology.
00:40:00 In this video, philosopher of science, Jack Lewis, discusses the theory of testing and how it works. He explains that a theory is tested by assuming certain background knowledge and variables that measure what they are supposed to measure. If the assumptions are met, then the theory can be said to be substantiated.
00:45:00 The philosopher discusses the concept of auxiliary assumptions in scientific theories. He argues that if these assumptions are not justified, then the theory cannot be trusted. The philosopher also discusses the use of norming studies and material checks in order to determine if the auxiliary assumptions are sound.
00:50:00 Popper and Lakatos argue that science is always provisional, and that any experiment that is conducted is open to criticism. They also argue that background knowledge is assumed in order for a test to be a test of a theory.
00:55:00 Philosopher of science Karl Popper and philosopher of mathematics Imre Lakatos argue that scientific theories are never definitively falsified, but are instead improved or replaced with new theories as scientists learn more about the world. Popper and Lakatos argue that scientists must commit in advance to what results they are looking for in order to falsify a theory, and that intellectual honesty is key to scientific progress.

The video discusses the philosophy of science and how it has been critiqued by Karl Popper and Imre Lakatos. Popperian philosophy holds that scientific theories are testable and that if one theory is found to be false, then it is eventually replaced by another theory that is more accurate. However, this lack of flexibility has led to the current biased scientific record. The video argues that Popperian philosophy should be amended to account for the possibility of a theory being found to be true even if it is difficult to verify.

01:00:00 The video discusses the philosophy of science and the criticisms of the "Popperian Paradigm." According to the video, Popperian philosophy holds that scientific theories are testable and that if one theory is found to be false, then it is eventually replaced by another theory that is more accurate. However, Popperian philosophy does not take into account the possibility of a theory that is found to be true, even though it may be difficult to verify. This lack of flexibility has led to the current biased scientific record. Pre-registered reports, which are a movement designed to create an unbiased record of scientific research, are a step in the right direction, according to the video. However, Popperian philosophy should be amended to account for the possibility of a theory being found to be true even if it is difficult to verify.
01:05:00 This video discusses the ideas of Karl Popper and Imre Lakatos on the nature of science. Popper argued that science is based on falsifiable hypotheses, while Lakatos argued that there are large-scale, relatively unfalsifiable research programs that are important in characterizing the nature of science. Popper accepted Lakatos' point that there are often metaphysical research programs in science.
01:10:00 In the video, philosopher of science, Paul Feyerabend, discusses the philosophy of Karl Popper and Imre Lakatos. Feyerabend argues that Popper's idea of falsifiability is not a requirement for a scientific theory, and that Lakatos' idea of critical realism is not a requirement for a scientific theory. Feyerabend also discusses the philosophy of science and how it relates to the philosophy of mathematics.
01:15:00 Popper and Lakatos argued that a scientific theory cannot be judged by its ability to be falsified, but by its ability to make novel predictions. If a scientific theory is in the process of degenerating, it is rational to give up on it.
01:20:00 The video discusses the ideas of the philosopher Karl Popper and the philosopher Peter Lakatos. Popper argued that theories can never be proven, while Lakatos argued that theories can be improved through critical thought. The video provides examples of how these ideas have been used in the field of psychology.
01:25:00 Philosophy of Science: Popper and Lakatos explores the idea of "hardcore" and "regressive" theories, and how they can be judged. The video discusses how a theory can be judged as being hard-core if it is not novel, and as being regressive if it is based on old data that has already been explained.
01:30:00 The video discusses the philosophy of science and how it applies to the concept of theories. It discusses the different types of theories and how they are judged. It also discusses the idea of predictions and how they are not always a direct result of a theory.
