#22"Extraordinary claims require extraordinary evidence" -- and I wouldn't count these small studies as extraordinary. Unfortunatley, publishing these kind of claims prematurely help the more gullible among us to fall for ridiculous claims from psychics and others who would take advantage of them. (The authors of "The Secret", I'm looking at you.) Commenters on NPR's website (not exactly the dumbest audience online) hav…
This type of attitude is infuriating - if a claim can survive the crucible of peer review then it we can be much, much more certain that it is true and correct. If humans were to posses a limited form of precognition that would be awesome - but before we can claim to posses a thing we must be sure that it is real.

#24See http://commonsenseatheism.com/wp-content/uploads/2010/11/Wag... ("Why Psychologists Must Change the Way They Analyze Their Data: The Case of Psi".) It demolishes the study referred to in the npr article.
Just reading it now -- seems like a very thorough takedown of the whole thing, in fairly non-technical language. It makes the very good point that this paper makes lots of statistical tests, and then bases big claims on the small minority that showed a significant effect. This is in no way restricted to psychology, drugs companies for example do this all the time. It's cheating, whether you realize it or not. Statist…
In other words, if you toss a coin 1,000 times, then it's hideously unlikely that you'll see a run of 100 consecutive heads. But if you toss the coin 100,000,000 times, you shouldn't be too surprised to see that 100-toss run buried in there somewhere, even though the odds of getting 100 in a row are so small.
Right?

#26Wow, the word retyping test seems like a total scam. Of course you're better able to recall words after a test in which you were already better able to recall those words. It's called memory. Correlation, not causation, as the maxim goes.
1. People recalled as many as possible.
2. People were divided into two groups, control and experimental.
3. Experimental group was asked to retype the words.
4. Control group was asked to go home.
5. Experimental group found to score better on initial test.

Can someone please, please explain this to me? I've never understood why the oft stated line "extraordinary claims require extraordinary evidence" is anything other than a clever saying. Why should it be that things that follow your intuition require any less rigor to prove than those that do not, and vice versa? Presumably there should be no subjectivity to cold hard science; evidence is evidence, and a certain quan…
It's simply the way Bayesian statistics work: if the prior probability of something happening is very low, then for me to flip from thinking "didn't happen" to "did" it will take some new information that is very powerful. If you think that's illogical, I'd ask you to consider why a teacher is more likely to accept the excuse "my dog ate my homework" than "aliens kidnapped me and stole it". You seem to be arguing tha…
In your example, based on existing data, it is indeed fair - some dogs do sometimes eat homework, whereas there are no verified accounts of aliens stealing it. So that's a legitimate adjustment of priors. Particularly if you actually have data on the incidence of paper-hungry dogs.
But in science and philosophy, there's lots of important questions for which we can't legitimately calculate priors, and "it would be too weird" is not at all relevant when determining their values.

the more tests you do, the sooner you'll see a fluke on average In other words, if you toss a coin 1,000 times, then it's hideously unlikely that you'll see a run of 100 consecutive heads. But if you toss the coin 100,000,000 times, you shouldn't be too surprised to see that 100-toss run buried in there somewhere, even though the odds of getting 100 in a row are so small. Right?
