Three stages of so what

Three things you can ask when told of a (psychological) phenomenon

1. Is it true?

Often you don’t need to look any further than disbelieving what you’ve been told. We only use 10% of our brains. You can remove the mystery implied by simply doubting the assertion. No one is influenced by adverts, so why do they spend money on them Etc. Not true, no mystery, no problem.

2. Is it real in and of itself?

Are we talking about something that is real and seperate from other effects we are familiar with, or is it just an consequence of something else (which we’ve already dealt with). You’re told The children of Israeli pilots are 70% boys. It seems to be true- is it worth worrying about? Only if the sex bias in the children born to Israeli pilots continues passed the point it was brought to your attention. Otherwise it’s just selection bias – of all the national & professional groups in the world something statistically unlikely had to happen to one of them, and that’s the one you got told about.

3. If it is true, and real, is it manifest?

Lots of phenomenon in psychology can be shown in controlled experiments, but it’s not clear that they manifest in any practical way amoung the noise and confusion of the real world. You’re told movement of light attached to people’s joints creates a powerful subjective impression of a full moving human form.. It’s true. It’s real (probably). Is it any use? Yes – we can use of flourescent markers at the joints of cyclists to tap into the specialised circuitry for figure perception and therefore make cyclists more visible, and thus more safe [1].

Quote #29

Sometimes it seems like we’re all living in some kind of prison, and the crime is how much we hate ourselves. It’s good to get really dressed up once in a while and admit the truth — that when you look really closely, people are so strange and so complicated that they’re actually beautiful. Possibly even me.

Writing tactics

I’m doing a lot of writing at the moment, here’s some things I remind myself – advice I’ve gathered along the way. I’m a big fan of advice, so thanks to all those who’ve offered it.

These are more tactics than principles or admonishments. I don’t always follow them, but sometimes they really help. Oh, and it’s non-fiction i’m writing in case anyone doesn’t know.

  • Andrew passed on the most important thing, as said by Kingsley Amis- The art of writing is the art of applying the seat of your trousers to the seat of your chair.
  • Dan Box said- Write in two-sentence paragraphs. Try it – you’re forced to structure your story so the direction is obvious, and structure your sentences so they are concise.
  • Tim Radford from the Guardian told me- Make the first sentence a summary of the whole article. This is for readers who don’t have any motivation except curiousity to keep reading what you’ve written . The newspaper story is top heavy, designed to be cut from the bottom- don’t have any surprises in the story outside the first paragraph, or outside the first few lines if you can help it.
  • I discovered the other day- When you’ve rewritten and rewritten until you can’t see the text anymore, put it in another application or change the font or style (or both). The superficial change to the appearence of the text really helps you read it again with something like full attention.
  • Mrs Ferris, my A-level history teacher said the first sentence of each paragraph summarises and defines what will be in that paragraph. Not only does this help orientation for people skimming what you’ve written, but it helps you structure it too. Good when writing for readers who don’t have much time (ie always).

    how to work with models

    Economist Paul Krugman writes ‘How I work’, and along the way covers some psychology-relevant thoughts on the use of models (as recommended by the Yale Perception and Cognition Lab).

    He also articulates one of my main reasons for having a weblog We just don’t see what we can’t formalize

    Linear development

    How wierd is this- I was looking at a review paper [1] of the development of visual acuity in human infants and I plotted the average acuity measurements for the first three years of life. It’s a straight line. A very straight line.

    Not only is it testament to the experimental rigour of the studies included in the review but it’s also pretty developmentally odd- I mean what else develops linearly? Height doesn’t. Vocabularly use doesn’t. Number conservation doesn’t.

    Does anything else develop linearly? There must be so many non-linear processes involved in the neural development of vision it’s a marvel it comes out linear with respect to age.

    Acuity was measured with black and white gratings of different spatial frequencies and is shown here in cpd, cycles per degree of visual angle (this is an inverse function of the Snellen rating (eg 20/20).

    and i ride my bike

    Getting a bike in London is like getting the freedom of the city. I now inhabit the city, rather than just being here. I move through space, making it my own, joining the dots of my knowledge. I’m no longer confined to small geographical areas and tube-teleported betweem them.

    The exploration-exploitation dilemma is crucially reweighted; exploration is cheap, exploitation is fun. I get lost easily. I get found easily. I move under my own power in the streams of the city traffic; I’m part of the flow.

    And it’s probably even healthy for me in some ways (as long as i don’t get killed).

    signs of nonsense

    One of the markers of pseudoscience is unrestrained endorsement. If you don’t have the resources or motivation to engage critical facilities, then you have to simply embrace everything that is suggested that doesn’t offend your broader instincts.

    Example: New-Age eclecticism. Example the second: psychobabble; as long as it has the words ‘neuro’ (for a business audience) or ‘psychodynamic’ (for a therapeutic audience) in it, you can probably get away with it.

    I shall add this to my heuristic-toolkit for the ‘how to deal with too much information’ problem…

    tired of london

    In 1777, Samuel Johnson wrote Why, Sir, you find no man, at all intellectual, who is willing to leave London. No, Sir, when a man is tired of London, he is tired of life; for there is in London all that life can afford. (link).

    In 1777, the population of London was approximately 800,000 people, a tenth it’s current size and a little larger than modern-day Leeds but smaller than Birmingham. (link)

    the obvious in psychology

    I mean, Christ, I’m not the first to say it, but some psychological research is just so obvious I want to bite out my own eyes. To pick unfairly, and at random, something I came across today, why exactly are we doing research like this? –

    “Women’s and Men’s Personal Goals During the Transition to Parenthood” (Salmela-Aro et al, 2000)
    Abstract: To investigate how women’s and men’s personal goals change during the transition to parenthood, the authors studied 348 women (152 primiparous and 196 multiparous) and 277 of their partners at 3 times: early in pregnancy, 1 month before the birth, and 3 months afterward. At each measurement, participants completed the Personal Project Analysis questionnaire (B. R. Little, 1983). The results showed that during pregnancy women became more interested in goals related to childbirth, the child’s health, and motherhood and less interested in achievement-related goals. After the birth women were more interested in family- and health-related issues. These changes were more substantial among the primiparous than among the multiparous mothers. Although the men’s personal goals changed during the transition to parenthood, these changes were less substantial than those found among the women. description and explanation in psychological science.

    Can this be as pointless as it sounds? Women worry more about impending motherhood while pregnant, and less about other things. Hold the front page.

    Now there’s a few arguments you can make for researching ‘common sense’.

  • you confirm 99% of it, but you falsify 1% of it, and that’s the important bit.
  • common sense is just a set of circumstance-variable prejudices. Not only does ‘common sense’ contain multiple, often erroneous and/or contradictory, positions, but it’s easy for people to say that’s just common sense after the fact.
  • it might be obvious that something is so, but exactly how is it so? Women deprioritise career-goals during pregnancy – obviously. But how much do they do this? What is the variation? How does this change across demographics? Across cultures? Across generations? (this said, if this is the main justification for the research then there is a fairly major problem with the communication of it).

  • But despite this, I think we’ve missed a fairly major distinction between description and explanation here. Psychological science needs more of the latter. An explanation provides a connection between different levels of descriptions or between different phenomenon. Granted, you have to sort your descriptions to some degree first before you can do this, but come on people

    And don’t think that I’m just talking about social psychology here. The brainporn fetish of cognitive neuroscience is just as much to blame. The next time I see a functional imaging study that demonstrates that a task involving mental activity requires various different bits of the cortex I shall weep.
    The added difficulty for social psychology is that most of the concepts involved
    have already had been explored with far greater finesse and insight than science can ever manage by millennia of culture activity. If you’re going to do some research here you need to bring some added value. Here’s my provisional list of those cases in which this might be possible:

  • When we know something to be true, but we need to know exactly how true it is – the extent, the variability, the limits of the effect and the interaction with other factors.
  • When we know something to be true, and science can show that it isn’t.(eg
    graphology, people wouldn’t electrocute others just because they are ordered
    to by a scientist). [and related to this]

  • When the common sense perception of individuals is persistently biased (eg self-rating of ability to detect lies, judgements about how fast queues move, perception of sleep duration among insomniacs, etc)
  • When we know something to be true, but we don’t know how or why it is true (enter, stage right, cognitive neuroscience and recourse to explanatory primitives from lower levels of description)

    when the free rider problem isn’t

    Great post at ambiguous.org about the free rider problem, and why it often isn’t. Read it for yourself, but essentially it says – and illustrates – that our dislike of social cheaters often leads us to want to make ‘fair’ systems that are working just fine despite- or because of- their tolerance for some degree of free-riding (thank to Matt at Interconneted.org for the link)

    The only true life i have is the life of my brain…

    Just found some transcriptions of Utah Philips’ Stories, from which this, a favourite of mine:

    That’s when [Fry Pan Jack] told me – you know, he’d been tramping since 1927 -he said, “I told myself in ’27, if I cannot dictate the conditions of my labor, I will henceforth cease to work.” Hah! You don’t have to go to college to figure these things out, no sir! He said, “I learned when I was young that the only true life I had was the life of my brain. But if it’s true the only real life I have is the life of my brain, what sense does it make to hand that brain to somebody for eight hours a day for their particular use on the presumption that at the end of the day they will give it back in an unmutilated condition?” Fat chance!

    fundamentalism in consumer culture

    If, like i said, social isolation is necessary to maintain ideological isolation, then here’s an extra irony to consumer culture: as The Market spreads across the world promoting Democracy and Freedom, it also extends the kind of atomisation that allows people to live in different social worlds than their neighbours and hence allows more ideological extremism.

    Ideological divergence because of more social isolation vs ideological homongenisation because of an increasingly similar macro-economic condition (ie consumer society).

    How the two forces will play out beats me

    describing systems / systems for describing

    Systems theory, like catastrophe theory before it, is a descriptive theory not a predictive theory. Which, means that it’s harder to say if it’s any use (and, indeed, you can always re-phrase any discoveries within that framework using the language of the old framework, once you have made them).

    Given this, we’d expect the most utility of systems theory to be in fields which are suffering most from a lack of adequate epistemological tools. Which is why, I guess, I’m convinced of the necessity of some kind of systems thinking in cognitive neuroscience and for social psychology.

    And why, maybe, to date the best systems theory work in psychology has been in developmental psychology

    The World Knot

    In a review by Steven Poole of Edelman and Tononi’s Consciousness: How Matter Becomes Imagination I found this:

    …they claim that Schopenhauer called the problem of consciousness the “world knot”, and adopt this lovely image as their catchphrase. But that is not what Schopenhauer said. What he calls the “world knot”, in On the Fourfold Root of the Principle of Sufficient Reason, is “the identity of the subject of willing with that of knowing”. Edelman and Tononi give a remarkably rich and provocative hypothesis of the subject of knowing, but the will soars free, as yet untethered by physical explanation.

    Great image – very norse – and the identity of the subject of will with the subject of knowing is definitely a biggie, both for the psychology and metaphysics of consciousness.

    Quote #25, Neoteny

    Reading Tom Robbin’s Still Life With Woodpecker on the tube this morning i was pleasently surprised by this:

    “Neoteny” is “remaining young”, and it may be ironic that it is so little known, because human evolution has been dominated by it. Humans have evolved to their relatively high state by retaining the immature characteristics of their ancestors. Humans are the most advanced of mammals — although a case could be made for the dolphins — because they seldom grow up. Behavioral traits such as curiosity about the world, flexibility of response, and playfulness are common to practically all young mammals but are usually rapidly lost with the onset of maturity in all but humans. Humanity has advanced, when it has advanced, not because it has been sober, responsible, and cautious, but because it has been playful, rebellious, and immature

    Ha! And with that, I’m off to the Hay Festival.

    Marketing (rant warning)

    Geoffrey Miller thinks marketing is the greatest invention of the last 2,000 years

    Hmmm…

    What he writes make me feel uncomfortable in a way I can’t really put my finger on. This means that either

    a) he is right, and I’m a damn liberal who can’t face up to the truth

    b) he is wrong, but in ever so subtle a way

    He says Almost everything we can buy is the result of some marketing people in some company thinking very hard about how to make us happy.

    Surely, it’s more accurate to say that almost everything we can buy is the result of some marketing people in some company thinking very hard about how to make us buy their stuff. This is an important difference.

    If, like he notes, the marketing orientation has become common in companies that make things for individual customers, like clothes, cars, televisions, and movies. It remains rare in heavy industry that produces steel, coal, oil, and paper, where the immediate consumers are other businesses

    isn’t this because businesses are subject to a different set of irrationalities than individual consumers?

    One important difference might be that businesses consumers aren’t divided and vastly outsized by their producers in the same way as individual consumers.

    Marketing makes us technology?s masters. This renders most of Marx irrelevant. What can alienation and exploitation mean when business listens so hard to our desires?

    I guess alienation can only make sense if people can become alienated from their own desires. Which is kind of a psychological-level version of Marxist false-consciousness anyway, and remains a pretty dirty theoretical trick.

    Doesn’t mean it isn’t true though.

    Like fish unaware of water, we do not realize that we live in the Age of Marketing…Democracy is simply the marketing concept applied to government.

    And there are different types of democracy, and democratic failures, just like there can be different types of markets and market failures. I have to be suspicious of anyone who tries to sell me One Market, or one notion of Democracy.

    Is the marketing revolution a good thing? On the upside, it promises a golden age when social institutions and markets are systematically organized to maximize human happiness.

    There’s that mistake again – maximising fallible human choices isn’t the same as maximising human happiness. But then, it’s hard to know what other indexes to use.

    On the downside, marketing is Buddha?s worst nightmare. It is the Veil of Maya made scientific and backed by billion-dollar campaigns. It perpetuates the grand illusion that desire leads to fulfillment..It is the enemy of human consciousness, because consciousness is content with its own company, and needs nothing from the world. The trouble is not that marketing promotes materialism. Quite the opposite. It promotes a narcissistic pseudo-spiritualism based on subjective pleasure, social status, romance, and life-style.

    A moment of clarity mixed with a moment of nonsense.

    Marketing brings more immediate problems. Like democracy, it forces intellectual elites to confront our patronizing attitudes towards the masses. Elites do not always like companies and states that provide what the people want….Marketing, like democracy, is anti-arrogance, anti-power, and anti-idealism….For the elite, marketing?s populism can be an alarming prospect….Cultural elites usually take a dim view of uncultured human nature to justify denying the power of choice to ordinary people. Fear of an economy based on market research, like Plato?s fear of democracy based on universal suffrage, is based on contempt for our species. Elites hate to recognize the marketing revolution because they hate to admit that contempt. Marketing is the most important invention of the last two millenia because it is the only revolution that has ever succeeded in bringing real power to the people.

    I look around at the six billion, as we break in waves of hunger a desire upon the eroded shore of history, and I wonder how we feel about our new, real, power. Power given to us – yes given! – by the wonderful power of marketing, marketers and the corporations that employ them.

    It is not just the power to redistribute wealth, to split the social cake into different pieces. Rather, it is the power to make our means of production transform the natural world into a playground for human passions. Marketing is not just the icing on the material world. It has become the recipe, the kitchen, and the cook.

    But marketing isn’t just a tool for working out what human desires are. Human desires are not some inviolate essence. They are created by social influences- created, evoked, and manipulated. Consciousness is not content with its own company, and needs nothing from the world. Consciousness is inherently social. We gauge our own status by social comparison, we want what others want, we believe what others in our tribe believe.

    Marketing is not an innocent observer in this scenario, no more than markets are spontaneous entities existing aside from politics and culture. All markets are designed by a set of socially sanctioned forces, and all marketing serves interests other than those of the consumers.

    visualisation of the dynamics of neural pruning

    Via futurepundit

    A time-lapse 3-D movie that compresses 15 years of human brain maturation, ages 5 to 20, into seconds shows gray matter – the working tissue of the brain’s cortex – diminishing in a back-to-front wave, likely reflecting the pruning of unused neuronal connections during the teen years. Cortex areas can be seen maturing at ages in which relevant cognitive and functional developmental milestones occur. The sequence of maturation also roughly parallels the evolution of the mammalian brain, suggest Drs. Nitin Gogtay, Judith Rapoport, NIMH, and Paul Thompson, Arthur Toga, UCLA, and colleagues, whose study is published online during the week of May 17, 2004 in The Proceedings of the National Academy of Sciences.

    The Development Set

    The Development Set
    By Ross Coggins

    Excuse me, friends, I must catch my jet-
    I’m off to join the Development Set;
    My bags are packed, and I’ve had all my shots,
    I have travelers’ checks, and pills for the trots

    The Development Set is bright and noble,
    Our thoughts are deep and our vision global;
    Although we move with the better classes,
    Our thoughts are always with the masses.

    In Sheraton hotels in scattered nations,
    We damn multinational corporations;
    Injustice seems so easy to protest,
    In such seething hotbeds of social rest.

    We discuss malnutrition over steaks
    And plan hunger talks during coffee breaks.
    Whether Asian floods or African drought,
    We face each issue with an open mouth.

    We bring in consultants whose circumlocution
    Raises difficulties for every solution-
    Thus guaranteeing continued good eating
    By showing the need for another meeting.

    The language of the Development Set
    Stretches the English alphabet;
    We use swell words like ‘epigenetic’,
    ‘Micro’, ‘Macro’. and ‘logarithmetic’.

    Development Set homes are extremely chic,
    Full of carvings, curios and draped with batik.
    Eye-level photographs subtly assure
    That your host is at home with the rich and the poor.

    Enough of these verses — on with the mission!
    Our task is as broad as the human condition!
    Just parry to God the biblical promise is true:
    The poor ye shall always have with you.

    Petty, unoriginal griefs

    Neil has some thoughts on The Black Rider:

    *what is it* I’m actually enjoying about this? It’s not the emotional resonance of well-drawn characters or the powerful realism of great acting or the engaging originality of cleverly-devised plots- I guess it’s the triumph of style over substance in both cases, but what style 😉 I also wondered whether one of the reason burlesque does work is because its cliche-laden expressions of cheap sentiment are actually a more realistic representation of a life characterised by the mundane scope of petty, unoriginal griefs, loves and yearnings than the grand passions and higher purposes portrayed elsewhere, but by treating it all with such irony manages to get away with the dramatic equivalent of adolescent poetry- expressing feelings in cloying and cliched terms that are utterly heartfelt and engulfing.

    How Creationists do peer-review

    Interesting post over at Panda’s Thumb on the ‘peer-review’ system of the International Society for Complexity, Information and Design – which is an Intelligent Design organisation (ie Creationist front).

    The thing i love about the creationists is that they can be so good at hitting upon genuine problems within evolutionary theory, and science and general, but their solutions are so WRONG.

    Anyway, one comment on the post is interesting

    Do y?all mind if I ask another stupid question?

    Is this site named ?Panda?s Thumb? or is it, ?Get Dembski??:)

    Here?s my background:

    1. I am an attorney, specializing in cancer cases;
    2. I, therefore, have to hire zillions of experts (pathologists, biochemists, oncologists, etc,) at usurious rates (sometimes up to $500/hour!)
    3. I, therefore, have to cross-examine the other side?s expensive, well-qualified experts at trial;
    4. I, therefore, know just enough science to make me dangerously, incompletely informed;
    5. I also get to see, first hand, numerous schisms in the scientific/medical community on numerous issues;
    6. But, I rarely see the rancor and teeth-gnashing exhibited in this debate, Evolution v. ID.

    That’s the thing isn’t it – just enough science to make me dangerously, incompletely informed. Now with a topic as large as evolution, who has the time or intellect to get completely informed? Apart from geniuses and fanatics, none of us. So we have to fall back on meta-theory to make decisions about which theories to accept. And part of meta-theory is world-view (ie axiom 1: believe the bible vs axiom 2: believe scientific orthodoxy).

    The creation-evolution debate will be an endless chase of fact, challenge and refutation until people start discussing why they believe things or why anyone should believe anything.

    And then we wheel out the two real strengths of evolutionary theory
    1. Parsimony – which also implies, incidentally, that even if evolutionary theory was wrong, there’s no good reason to believe that the Christian bible is right).
    2. Generativity – the ability of a research programme to generate new insight over time, rather than just adjust itself to new evidence in an ad-hoc manner is crucial.
