I’ve read his newest book, “Meditating Selflessly: Practical Neural Zen”, that seems to be aimed more at a layperson than “Zen and the Brain”. It also talks a bit about his speculations about what meditation does in the brain, along with some recommendations on meditation. It might be too speculative though.

He also has a third book, perhaps that is a happy medium? Depending on how motivated you are, you might even try one of those Human Brain coloring books...

in reply to: Dorikka’s comment on: How to Learn from Experts
There are a couple chapters in there on the subject, but it’s probably not the best book specifically for that subject. I haven’t read it yet, but “Working Minds: A Practitioner’s Guide to Cognitive Task Analysis ” looks pretty good. One of the people behind the method wrote several books for a general audience and one of them, “The Power of Intuition” (not what it sounds like) has a few tips on how to learn from experts:

*Probe for specific incidents and stories. This is not the same thing as listening to war stories. It means selecting incidents where intuition was needed, and expertise was challenged, and then digging into the details.

*Ask about cues and patterns. Try to find out what the expert was noticing while making sense of the situation. You want to uncover types of discriminations that the expert has learned to make, types of patterns the expert has learned to recognize. The decision-making critique can suggest lines of questioning.

There’s more, but I don’t want to quote too much… One of the other tips is to ask how a novice would approach things vs how they would. He also recommends avoiding asking for general theories, the experts may not really be able to describe how/what they do without having a story to guide them.

That is a good point, I’ve only just begun to look into it, so I don’t have any general recommendations. It just seemed like as I was coming up with a reading list on reading, some books seemed to pop up in Amazon’s “people also bought” section. I think part of it is because the guy who wrote “How to Read a Book” was heavily influenced by Thomas Aquinas. I also looked up hermeneutics afterwards and it seemed appropriate for what I was trying to do. One key takeaway seems to be looking at reading as work...

One book that I was looking at was “Inductive Bible Study: A Comprehensive Guide to the Practice of Hermeneutics” by Traina, as the table of contents looked interesting (survey of books as wholes, survey of parts as wholes, selecting questions and formulating premises, drawing inferences, evaluating and appropriating, correlation,...). Haven’t got to it yet though.

I’ve recently made an effort to start getting more out of the reading that I do, I think one of the simplest things to do is to close the book every few minutes and summarize what you’ve just read. Writing down those summaries is even more effective. I’m sure people who post reviews and summaries (see some of the recent ones posted here for example) have a far better understanding of the material than if they just read it.

One book that might be helpful is “How To Read A Book” by Mortimer Adler. It talks about different stages of reading, questions to ask yourself, and other strategies. If you don’t want to buy the book (it’s fairly cheap), there are numerous summaries online. If you buy it though, you get a free book to practice on. Here is an excerpt on reading multiple books on a given topic:
I. Surveying the Field Preparatory to Syntopical Reading
1. Create a tentative bibliography of your subject by recourse to library catalogues, advisors, and bibliographies in books.
2. Inspect all of the books on the tentative bibliography to ascertain which are germane to your subject, and also to acquire a clearer idea of the subject. Note: These two steps are not, strictly speaking, chronologically distinct; that is, the two steps have an effect on each other, with the second, in particular, serving to modify the first.
II. Syntopical Reading of the Bibliography Amassed in Stage I
1. Inspect the books already identified as relevant to your subject in Stage I in order to find the most relevant passages.
2. Bring the authors to terms by constructing a neutral terminology of the subject that all, or the great majority, of the authors can be interpreted as employing, whether they actually employ the words or not.
3. Establish a set of neutral propositions for all of the authors by framing a set of questions to which all or most of the authors can be interpreted as giving answers, whether they actually treat the questions explicitly or not.
4. Define the issues, both major and minor ones, by ranging the opposing answers of authors to the various questions on one side of an issue or another. You should remember that an issue does not always exist explicitly between or among authors, but that it sometimes has to be constructed by interpretation of the authors’ views on matters that may not have been their primary concern.
5. Analyze the discussion by ordering the questions and issues in such a way as to throw maximum light on the subject. More general issues should precede less general ones, and relations among issues should be clearly indicated. Note: Dialectical detachment or objectivity should, ideally, be maintained throughout. One way to insure this is always to accompany an interpretation of an author’s views on an issue with an actual quotation from his text.
Another book I’m looking into (but haven’t yet read) is Cognitive Productivity. Also, if you are open to it, you might consider reading a book on studying the Bible. It’s really a series of connected books with lots of self reference and people have been studying it for a long time, so there is a lot on the topic. It’s called Hermeneutics, and while I used the Bible as an example (because of the wealth of material on its study) hermeneutics is used elsewhere (other religious traditions, law, philosophy, etc).

on: One thousand tips do not make a system
I’ve advocated Gary Klein’s work here before (Deliberate Practice for Decision Making ), you may find his latest book Streetlights and Shadows interesting.

The problem is that procedures are a system that describes how to react, but the model of reality that those procedures are based on is incomplete and may be contradictory (see Gödel’s Incompleteness Theorem, though I may be generalizing it too much). The Drefus Model of Expertise lines up fairly well with your final questions, particularly the “Expert” stage. Unfortunately, it describe how one can develop that expertise or the answers to the questions.

The problem is that we don’t know if Einstein not being neuortypical is the cause of his genius, or the result of a lifetime of thinking in a certain way. Brains aren’t static and can change over time, it’s entirely possible he was born with a neurotypical brain that became aytpical over the course of his life.

in reply to: Oscar_Cunningham’s comment on: [Draft] Productive Use of Heuristics and Biases
After doing a bit more reading here and thinking about your comments, I think I’ll focus on the 7 methods and eliminate much of the low quality fluff that make up the intro/conclusion for the next version.

I think some of my confusion was due to unsubstantiated assumptions about the standard views of LessWrong. What I’ve been thinking of bias is closer to Inductive bias than the standard definition, which refers to error patterns. I then interpreted rationality as “overcoming bias”. Inductive bias can be useful, and the idea of overcoming bias of that type seemed to be taking things too far. That doesn’t seem to be what anyone is actually advocating here though.

Again, thanks.

I agree that the only way to practice decisions is to make them, but I think there is more to it than that. The deliberate part of deliberate practice is that you are actively trying to get better. The deliberate performance paper I linked to touches on this a bit, in that deliberate practice is challenging for professionals and that something else might work better (they advocate the first 5 methods in that paper).

Beyond making decisions, you need to have an expectation of what will happen, otherwise hindsight bias is that much harder to overcome. It’s the scientific method: hypothesis->test->new hypothesis. Without defining what you expect ahead of time, it is much easier to just say “Oh yeah, this makes sense” and normalize without actually improving understanding.

in reply to: NancyLebovitz’s comment on: [Draft] Productive Use of Heuristics and Biases
Something like this was discussed by Kelly McGonigal in “The Willpower Instinct”. A couple things that might help:

Avoidance—Complete avoidance is probably impossible, but you might try limiting your exposure to such things, particularly when you are vulnerable to making poor decisions. The old advice “don’t go to the store when your hungry”, might be related to low glucose levels (which affect decisionmaking).

Controlled exposure w/ reflection—I remember wanting toys when I was younger based on what was shown in commercials. After a couple disappointments, I got a little better resisting the ads. That said, I could probably use some recalibration…

All in all, mindfulness and an information diet. I’ve seen this particular field (ads, store layouts, etc) referred to as choice architecture, perhaps you could do some choice architecture of your own, to guard when your defenses are down. Essentially, develop good routines and make good choices ahead of time and stick to them.

tracks progress on those goals, and charts overall utility.

I don’t think it works very well for what you are envisioning, but something like spaced repetition software might help.

With SRS, the idea is that the software tries to figure out when you are going to forget something and prompts you at that time, when the reminder will be most effective.

An alternative to improving your intuition and removing your biases would be to find other and better processes and tools to rely on. And then actually use them.

I think that is part of what I was attempting to get at, though I probably didn’t do a very good job. In a sense we are biased to use certain processes or tools. The only way to change those “default settings” is to deliberately practice something better, so that when the time comes, you’ll be ready.

Thanks for the comments, criticism is welcomed.

I think the standard font-size on LessWrong is smaller. Most people would prefer it if you used that.

Apologies for the font size, I was editing in Google Docs rather than the post editor...

As I say above, this is really just a terminological difference, but I think that making it will clarify some of the ideas in the post. In particular, I think that the main content of the post (the seven ways of improving our heuristic judgements), is really useful instrumental rationality, but that the introduction and conclusion hide it in poorly backed up statements about how reducing bias is less important than using good heuristics. I find it strange that these things are even presented in contrast; the techniques you give for improving intuition are techniques for reducing bias. The intuitive judgements become more accurate (i.e. less biased) than they were before.

I admit, terminology is an issue. I perhaps bit off a bit more than I can chew for a first post. I’ll try to fix that.

One final thought: Do the seven methods really focus on System 1 only? Many of them seem like general purpose techniques, an in particular I think that 4, 5, 6,and 7 are actually more System 2.

From the way Klein describes them, they are meant to accelerate expertise. If my interpretation is correct, they are using system 2 to develop system1 for the next scenario. I think part of the problem with how I’m describing this is that experience, which is instrumental in developing expertise, develops intuition. Intuition can either help or hurt. Sometimes we won’t know which until after a decision has been made, other times we might be able to prevent mistakes by running through a checklist of cognitive biases. In the former case, the methods should help next time. In the latter case, you need something (from system 1 for example) to run through the checklist. The checklist on its own isn’t very useful.

Again, thanks for the feedback.

Simon’s writing style seems a little strange to me for what its worth...

There are few others who have worked with with him and described their impressions of how he worked. Those might be more readable, but Hamming’s lecture/paper is hard to beat in my opinion.

http://web.cs.dal.ca/~eem/gradResources/HerbertSimon.pdf http://www.isle.org/~langley/papers/has.essay.pdf

I attempted to summarize the three papers and incorporate a few other things a while ago, inspired in part by a post by Cal Newport of StudyHacks on the methods of Feynman and a few others. Incidentally, Cal has colloborated in the past with the author of the Holistic Learning ebook in the OP.

Cal’s post: http://calnewport.com/blog/2012/06/18/impact-algorithms-strategies-remarkable-people-use-to-accomplish-remarkable-things/ My summary of Simon’s Methods: https://sites.google.com/site/wattsd/simplesimon

The summary is still rough and incomplete, so the sources might be more interesting/useful.

Hamming’s “You and Your Research” and Herbert Simon’s “The Scientist as Problem Solver” are good “How I do research” papers. Hamming’s paper was described in the other comments. Simon won both a Turing award and a Nobel prize.

in reply to: [deleted]’s comment on: Attention control is critical for changing/increasing/altering motivation
I’m not sure there is a study about directing attention to pain, but there is a video game being used to reduce pain, presumably by directing attention away from it.

http://www.hitl.washington.edu/research/vrpain/

Edit: From the page:

Patients often report re-living their original burn experience during wound care, SnowWorld was designed to help put out the fire. Our logic for why VR will reduce pain is as follows. Pain perception has a strong psychological component. The same incoming pain signal can be interpreted as painful or not, depending on what the patient is thinking. Pain requires conscious attention. The essence of VR is the illusion users have of going inside the computer-generated environment. Being drawn into another world drains a lot of attentional resources, leaving less attention available to process pain signals. Conscious attention is like a spotlight. Usually it is focused on the pain and woundcare. We are luring that spotlight into the virtual world. Rather than having pain as the focus of their attention, for many patients in VR, the wound care becomes more of an annoyance, distracting them from their primary goal of exploring the virtual world.

in reply to: Vladimir_Golovin’s comment on: Attention control is critical for changing/increasing/altering motivation
The concept being described in the article sounds very similar to deliberate practice, which I think might be described as keeping what you are trying to practice at conscious level instead of going on autopilot.

Many of those studies are actually based on chess, so if this describes how deliberate practice changes the brain, it should also map to higher level activities.

Of course, I’m not terribly familiar with all of the relevant science either.
