Feyerabend's counterinduction and Bayesianism. Has anyone here thought about how these two views of science bear on each other?
Belief & double-blind randomized control group studies: response to IlyaShpitser
In a previous thread IlyaShpitser said >According to your blog, you don't believe in RCTs, right? What do you believe in?
This is part of the problem I'm trying to address. Belief/non-belief are inappropriate locutions to use in terms not only of the double-blind randomized control group method (DBRCGM), but of models and methods of science in general. "Belief in" a any scientific method is not even remotely relevant to science or the philosophy of science. Also, I did not say that the DBRCGM is entirely useless. All I'm really saying is it can be improved upon. Furthermore, what I "believe in" is almost entirely irrelevant to my appreciation of Bayesiansim and other forms of scientific fallibilistic flexibility. When we "believe in" something, we allay our curiosity and create unnecessary obstacles for the mind changes Bayesianism and fallibilistic flexibility encourage us to practice.
Do you believe the nutritional etiology of scurvy?
Yes.
This is a good one. I definitely sympathize with Eliezer's point that Bayesian probability theory is only part of the solution. e.g., in philosophy of science, the deductive-nomological account of scientific explanation is being displaced by a mechanistic view of explanation. In this context, a mechanism is an organization of parts which is responsible for some phenomena. This change is driven by the inapplicability of D-N to certain areas of science, especially the biomedical sciences, where matters are more complex and we can't really deduce conclusions from universal laws; instead, people are treating law-like regularity as phenomena to be explained by appeal to the organized interactions of underlying parts.
e.g., Instead of explaining, "You display symptoms Y; All people with symptoms Y have disease X; Therefore, you have disease X," mechanists explain by positing a mechanism, the functioning of which constitutes the phenomena to be explained. This seems to me to be intimately related to Eliezer's "reduce-to-algorithm" stance; and that an appeal to reduce abstract beliefs to physical mechanisms seems to be a pretty good way to generalize his stance here. In addition, certain mechanistic philosophers have done work to connect mechanisms and mechanistic explanation with Bayesian probability, and with Pearl's work on Bayesian networks and causality. Jon Williamson at Kent has my favorite account: he uses Recursive Bayesian Networks to model this sort of mechanistic thinking quantitatively.

If you look at the wikipedia page that describes fallibilism, the word probability doesn't directly appear. In the main body of the article.
People like Pyrrho were practicing fallibilism long before the kind of math that you need to think about probabilities that you can multiple with each other got invented.
So the underlying philosophies are extremely similar if not the same even though the methods, largely due to practical problems (lack or presence of mathematical tools)?
What are the differences and similarities between fallibilism and Bayesianism?
Per, see the SEP entry or Wikipedia entry on Behaviorism. Skinner, in particular, does appear to have espoused that version from what I can make out.
I don't expect there are many Skinnerian behaviorists left nowadays, but the memes are still floating around in fields outside psychology.
Really? "Skinnerian" behaviorism (Skinner preferred the term "radical behaviorism") is thriving.
The Perfected Self B. F. Skinner’s notorious theory of behavior modification was denounced by critics 50 years ago as a fascist, manipulative vehicle for government control. But Skinner’s ideas are making an unlikely comeback today, powered by smartphone apps that are transforming us into thinner, richer, all-around-better versions of ourselves. The only thing we have to give up? Free will (The Atlantic Monthly, June 2012).
I personally know several radical behaviorists/applied behavior analysts working in the social services and animal control/training fields, and operant learning is still a staple of educational training and delivery.
Nobody likes to think of themselves as governed by the same laws pigeons in a Skinner box are, but.... Try this thought experiment: think back over the past 24 hrs. of your life. How many levers, buttons, etc..., have you manipulated in that sample? Now, imagine for some reason in that time frame you were restricted from using any levers, buttons, etc.... Like my wife said when I ran it not her, "Makes it virtually impossible to get shit done."
Eliezer_Yudkowsky (EY) said (above):
Let me see if I understand your thesis. You think we shouldn't anthropomorphize people?" -- Sidney Morgenbesser to B. F. Skinner
- As far as I've I can tell, this never happened.
- Perhaps your understanding of "anthropomorphic" is too narrow?
EY said (above):
Behaviorism was the doctrine that it was unscientific for a psychologist to ascribe emotions, beliefs, thoughts, to a human being.
This is the basic myth. Skinner fought very hard to demonstrate that this was a gross mischaracterization of behaviorism.
EY said (above):
But for the behaviorists to react to the sins of Freudian psychoanalysis and substance dualism, by saying that the subject matter of empathic inference did not exist... Which behaviorist? Where? When?
Added: I found it difficult to track down primary source material online, but behaviorism-as-denial-of-mental does not seem to be a straw depiction. I was able to track down at least one major behaviorist (J.B. Watson, founder of behaviorism) saying outright "There is no mind."
This should make plain why Watson was never behaviorist poster boy material. I wouldn't even call him a "major" behaviorist.
Mysticism isn't a topic that LW has paid any attention to.
Meditation has received some attention here, though I can't think of other sorts of mysticism. Perhaps Crowley's writings.
Would you please refer me to the discussions on meditation you're thinking of?
This is a sticky subject. "Meditation" and "mysticism" differ from context to context. E.g., Christian mysticism (the telos of which is union with God) and what Crowley meant by mysticism are fundamentally different (the latter sharing more in common with Hindu yogi praxis where union or samādhi is not necessarily restricted to a Diety; and in Buddhist mediation the purpose of samādhi is subsumed under a different goal altogether.). Meditation can refer to so many different things the term is basically useless unless one gets very specific. But I'm not sure if that serve LW's purposes so I'll hold off saying anything else for now.

I don't understand why you're getting downvoted. Those were great links, and indeed relevant. I appreciated them.
Thanks. I don't know either. That's why I don't come here that often. The karma points system doesn't serve the aims of science. It serves the "scientific consensus" myth which is mostly a glorified popularity contest without regard for fallibilism, iteration, paradigm shifting and counterinduction.
