comment What causes systematic under- or over-estimation of general knowledge quantities?
Yes, I think you are right in that example. That's part of the problem with the heuristics approach: there have been dozens of reported heuristics, but often it is not clear a priori which heuristic we might use for any given problem (though see Payne, Bettman & Johnson, 1988; Shah & Oppenheimer, 2008; etc)

comment Is it easier for people to remember longer words than words mixed with symbols?
@zergylord it's pretty unreasonable. my keyboard doesn't have anywhere close to 107 non-alpha characters, and it's quite unreasonable to think many people use charmap to type in their passwords. I would delete it, yes.

comment Why do you sometimes write down one word while actually intending to write another?
@Mien I don't know of a paper that specifically looks at that aspect (though there may be one-- I haven't looked). However, 1) if you're willing to accept that Dell's model affects your tongue and jaw muscles, it seems a small leap that it would affect your fingers as well; 2) Botvinick & Plaut (2004) present a popular connectionist model of motor action selection that references Dell several times-- probably a good place to start.

comment Do porn and other remotely perceived entertainments work because of Mirror Neurons?
@Comptrol Ben is not refuting your claim. See ahealthymind.org/library/Hickock%20Mirror%20neurons%2009.pdf for a review on the controversy (from one perspective).

comment Why do dual N-back games use certain letters?
I don't know that it always has to use those letters. (see www.brainboffin.com; also, a quick lit search shows it's also been done with numbers and Mandarin phonemes). I suspect it's partly to do with the phonetic properties of the sounds, as Ben Brocka suggests, and partly because the dual n-back has mostly been run by a single lab (Jaeggi). It's easier for them to consistently use the same experimental setup, and increases their chances of reproducing the effect.
