Karl Popper, Science, & Pseudoscience: Crash Course Philosophy #8

50 Comments

1. I want to understand how scientific falsification dialogues with the epistemic thesis about knowledge from falsehood.

2. The next episode follows perfectly after this one

3. Mmm Im gonna need more examples on how to disprove stuff other than the Santa example. So we should go around searching for contrary evidence is that it?

4. Science dis-confirms, pseudoscience confirms

5. Rene Descarte already came up with this , it’s called Cartesian doubt.

6. Great video.
   Testable
   Refutable
   Falsifiable

7. 3:19 lol I thought he turned Italian for a second… "So, you look-a-da-swan!"

8. "Let your beliefs go". dont you love when you see someone teaching about a topic they genuinely have no idea about. Hilarious

9. I-

10. The Case for God. Great movie using science.

11. I finally have an answer to the question my stat professor could never answer for me as to why we do not accept the null hypothesis, but "fail to reject" it instead. Thank you!

12. One of your best videos yet!

13. I love this video…but, when it was over, youtube gave me a commercial for witch hazel. Youtube needs to study Popper

14. Man made climate change…pseudo science

15. I will always always always be thankful for this channel because they have videos for nearly every topic.

16. allow me to preface this with the fact that I'm a scientist and an atheist. I can scientifically confirm that punching the average in the nose hard enough to break it hurts them via observation, data or a combination of the two. That's not pseudoscience, it's pure science. The fact is that science must either confirm or disconfirm depending on the situation. Just like nature vs. nurture, it's a bit of both.

17. Climate Change is UN'FALSIFIABLE , just saying.

18. This is the only guy I disagree with. Sure, it can work with smaller ideas but not bigger ones…

19. Psychology/psychiatry is pseudoscience and very destructive to society and mankind.

20. How santa clause is real when everyone knows is an invented story ?

21. Sounds like math

22. Freud was a theorist/practitioner. In those days, counselors were neurologists and doctors. He wasn't a scientist and never purported to be. Now we accept most of the things he was right about as common sense anyway but people only seem to look at his failures.

23. Scientific theory is about disproving? That's been lost for awhile. People don't want to read a report stating why this isn't true. If an experiment doesn't give you what you want, change it till it does.

24. Could it happen that something is unfalseable and still true?

25. I love you @CrashCourse

26. Does that make the Evolution Theory part of science or pseudoscience ??????

27. But what if my dad is the real Santa?

28. A great video for EVERY person to watch and understand why scientific theories are more valuable and pseudo-scientific ones.

29. Popper was a great thinker, truly. It would behoove any rational debunker-type to closely study his ideas. The philosophically unsophisticated can be made to look like fools, even if they are defending sound points.

30. I'd like to think that my beliefs, mostly scientific, are contingent. However, that's just led to a bunch of 'back and forth' and crazy conflicts in my head. I get caught up thinking about the many answers and just end up confused about all of life lol.

31. There is one thing I'm curious about though: if being certain of something causes you to close your mind, is it likely that religious people who have a set of "certain" beliefs tend to be less open minded? I identify myself as a religious person and I would say that I'm open to other beliefs that might even contradict my own. But I would also argue that people need to be certain of something. If you question everything nonstop it will become mentally strenous. I think that falsification is a legitimate ideal for modern science, however it's not always realistic. We are humans after all and very biased (no matter how hard we try to avoid that or overcome it).

32. Science also confirms things if anything exists based on empirical evidences like earth is made up of matter, what do you think? And do pseudo science helps to disapprove anything too? Then would it be called pseudo science? Please guide me.

33. What was Austria doing right before they did it all wrong

34. "You have to be open to the idea that your beliefs might be false, because that's the only way that holding onto them can really mean anything." quoted.

35. Psychology is not science!

36. poppers.

37. 2:56 Wrong. René Descartes published in the second part of his Discourse of the Method a way to determine the validity of each and every one of his beliefs; we know call this method as the Cartesian Method. In a nutshell, system was composed of these 4 steps:
    1)Never believe anything that is unproven
    2)Divide whatever problem he faces into as many parts as possible and/or needed
    3)Organize the information attained from these problems from simpler to more complex.
    4)Check your progress to make sure you didn’t skip anything.

38. more pauses between speaking please. it sounds like you are interrupting yourself.

39. The example with the swans is NOT a use of the deductive method/argument. It is the INDUCTIVE. Collecting specific data and turning it into a general theory = the inductive method/argument.

40. But it was imagination and curiosity that gave birth to human intellect,science, reason and scientific theory. Other animals don't have imagination. Its why we think we're special and delusional.

41. If only Nathan Oakley, Nathan Thompson, JM Truth, Sleeping Warrior and all the other flat earth IDIOTS can understand this (they never will).

42. Testable, refutable, falsifiable! All my experiments shall serve to crush the theories from which they were born muahahahaha

43. Good short vid!

44. I'm open to the idea that psychology is a science. However there is an overabundance of pseudoscience in the field.

45. There's no subtitles??

46. Hi Crash Course, I just wikipedia the name psuedo and this is what it had to say:
    pseudo
    
    /ˈsjuːdəʊ/
    
    Learn to pronounce
    
    INFORMAL
    
    adjective
    
    1.
    
    not genuine; spurious or sham.
    
    "we are talking about real journalists and not the pseudo kind"

    noun
    
    1.
    
    a pretentious or insincere person.
    
    So how can psuedo science confirm something that is not real as per example used or per notion that psuedo is not genuine. how is thus possible to confirm that which is bogus, I presume you conflating ideas on your video layout 4:36

47. Was love proven to be a fact? A feeling on levels based on what we observe, are told, or watch on television, etc?

48. ?

49. Predictive power: what makes science so useful and the closest we can get to determining truth

50. Before the popper, the Viennese circle talked about the same thing. And unless, without a popper, scientists did not worth the theory and did not set up experiments? Where is the evidence that his constancy fact really influenced something?
