Why Are We Such Bad Introspectors?

Sahar Joakim interviewed me earlier this week for her philosophy video series.  Thanks, Sahar!  We discussed the nature of consciousness, the unreliability of introspective reports of conscious experience, and how sparse or abundant consciousness is, both across animal species (e.g., are snails conscious?) and in your own mind (e.g., do you have constant tactile experience of your feet in your shoes?).



At one point Sahar asked, if it's true that people are bad introspectors, why is that so?  What makes introspection so difficult?  I have a theory about this, but I've never published an article directly on the topic.  So here's a brief discussion (some of the below is adapted from Chapter 3.3 of my 2007 book with Russ Hurlburt).

Before getting into the details, let me briefly sketch my target.  The principal target of my skepticism about introspection concerns large-to-medium-sized structural features of currently ongoing conscious experience.  An example of what I'm not skeptical about is this: If you think you're thinking of a banana, probably it's true that you are thinking of a banana.  The introspective judgment "I'm thinking of a banana" might even contain within it the thought of a banana, making it automatically self-fulfilling.

However, what you don't know so well, I've argued, are the structural features of that thought, for example, whether it is in inner speech (words you silently speak to yourself), or inner hearing (auditory imagery that is experienced as being more passive than inner speech), or whether it is to some extent also, or instead, an imageless/wordless "unsymbolized thought", or....  Even if you might rightly be confident about the coarsest-level distinction here -- for example, that it's a thought specifically in inner speech as opposed to some other modality -- the basic structural features of that inner speech experience can be difficult to know.  Is the speech at a normal pace relative to ordinary speech or does it transpire more quickly?  Is the speech experienced as located somewhere, e.g., in the center of your head, versus somewhere else or nowhere?  Is there some distinctive feeling of understanding that accompanies the inner speech?  (See Chapter 4 of my book with Hurlburt for discussion of these issues in the context of an actual sampled instance of reported inner speech by an introspective research participant.)

Alternatively, consider your current visual experience.  How stable is it?  How clear and distinct are shapes and colors in the periphery?  It is in some respect flat, like a photograph, or does it have some real depth beyond what is possible in a photograph?  If the latter, does the depth of it change dramatically when you close one eye?  (See herehere, and here for more discussion of these issues.)

You might not be convinced that introspection of the large-to-medium-sized structural features of your ongoing conscious experience is as difficult as I suggest.  But hopefully you at least have a sense of what my position is.  Now, to Sahar's question.  Why is it so difficult?  In the interview, I listed three reasons.  Here, I'll expand those reasons into five.  None of these reasons, by itself, needs to make introspection super difficult.  But combined, they create quite a set of obstacles to good self-knowledge.

First, experience is fleeting and changeable – or so it seems to me right now as I reflect, introspectively, upon it.  The screen of text before me, as I reread these paragraphs, is relatively steady; but my visual experience as I look at the text is in constant flux.  As my eyes move, the portion that’s clear, the portion that’s hazy, constantly changes.  I blink, I glance away, I change my focus, and my experience shifts.  My eyes slowly adapt to the black and white of the screen, to the contrast with the surrounding desk, to the changing light as the sun goes behind a cloud.  I parse some bit of the page into familiar words as my eye scans down it; I form a visual image, reflecting the content of the discussion; my attention wanders.  All this, it seems, affects my visual experience.

Consider your own experience as you read this paragraph.  The text in your hands changes not a whit, but your visual phenomenology won’t stay still a second, will it?  (Or will it?)  The same is true, I’m inclined to think, for our auditory experience, emotional experience, somatic experience, conscious thought and imagery, taste, and so on: Even when the outside environment is relatively steady, the stream of experience flies swiftly.  It won’t hold still to be examined.

Second, we’re not in the habit of attending introspectively to experience.  Generally, we care more about physical objects in the world around us, and about our and others’ situation and prospects, than about our conscious experience, except when that experience is acutely negative, as with the onset of severe pain.  This may seem strange, given the importance we sometimes claim for “happiness,” which we generally construe as bound up with, or even reducible to, emotional experience – but despite the lip service, few people make a real study of their phenomenology.  We spend much more time thinking about, and have much subtler an appreciation of, our outward occupations and hobbies.  And when we do “introspect,” we tend to think about such things as our motives for past actions, our personality traits and character, our desires for the future.  This is not the sort of introspective attention to currently ongoing (or immediately past) conscious experience around which my skepticism turns (though I am also skeptical of much of this purported knowledge, on different grounds).  Introspective attention to experience is hardly a habitual practice for most, perhaps any, of us, except maybe a few dedicated meditators of a certain sort.

If accurate introspection requires a degree of skill, as I suspect it does, in most people the skill is uncultivated.  Furthermore, relatedly, experience is difficult to remember: Generally what we remember are outward objects and events – or, rather, outward objects and events as interpreted, and possibly misperceived, by us – not our stream of experience as we witness those objects and events.  We remember, usually, that the boss said the work wasn’t up to snuff, not that our visual experience as he said it was such-and-such or that we felt some particular sinking feeling in the stomach afterward.  These conscious experiences fade like dreams in the morning unless, as with dreams, we fix them in mind with deliberate attention within a very short space.  

Third, in part due to our disinterest in conscious experience, the concepts and categories available to characterize conscious experience are limited and derivative.  Most language for sensory experience is adapted from the language we use to describe outward objects of sensation.  Objects are red or square or salty or rough, and usually when we use the words “red” and “square” and “salty” and “rough,” we are referring to the properties of outward objects; but derivatively we also use those words to describe the sensory experiences normally produced by such objects.  That’s fine as far as it goes, but it’s prone to invite confusion between the properties of objects and the properties of experiences of those objects.  The practitioners of certain specialties – for example, wine tasting and sound engineering – have refined language to discuss sensory experience, but even here our conceptual categories are only rough tools for describing the overall experience.  And, anyway, isn’t the gustatory experience of eating a burrito as complex as that of tasting a mature wine, and the auditory experience of sitting in a restaurant as complex as that of hearing a well-played violin?  We almost completely lack the concepts and competencies that would allow us to parse and think about, talk about and remember, this complexity.

Fourth, the introspection of current experience requires attention to (or thought about) that experience, at least in the methodologically central case of deliberately introspecting with the aim of producing an accurate report.  Problematic interference between the conscious experience and the introspective activity thus threatens.  Philosophers and psychologists going back at least to August Comte have complained that the act of introspection either alters or destroys the target experience, making accurate report impossible.  Much of experience is skittish – as soon as we think about it, it flits away.  Suppose you reflect on the emotional experience of simple, reactive anger, or the auditory experience of hearing someone speak.  Mightn’t the self-reflective versions of those experiences – those experiences as they present themselves to concurrent introspection – be quite different from those experiences as they normally occur in the unselfconscious flow of daily life?  A number of psychologists have attempted to remedy this difficulty by recommending immediate retrospection, or recall, of past experience rather than concurrent introspection as the primary method (e.g., James, 1890/1981).  However, deliberately poising oneself in advance to report something retrospectively may also interfere with the process to be reported; and if one only reports experiences sufficiently salient and interesting to produce immediate spontaneous retrospection, one will get a very biased sample.  Furthermore, retrospection is likely to aggravate the fifth problem, namely: 

Fifth, reports of experience are apt to be considerably influenced, and distorted, by pre-existing theories, opinions, and biases, both cultural and personal, as well as situational demands. The gravity of this problem is difficult to estimate, but in my opinion it is extreme (and considerably larger than the influence of bias and preconception now generally recognized to permeate science as a whole).  Given the changeability and skittishness of experience, and our poor tools and limited practice in conceptualizing and remembering it, we lean especially heavily on implicit assumptions and indirect evidence in reaching our introspective and immediately retrospective judgments.  One major source of such error is what the introspective psychologist E. B. Titchener called “stimulus error”: We know what the world, or a particular stimulus, is like (we know for example that we are seeing a uniformly colored red object), and we are apt to infer that our experience has the properties one might naively expect such a stimulus to produce (e.g., a visual experience of uniform “redness”).  We’re much better accustomed to attend to the world than to our experience, and the difference between sensory attention to outside objects and introspective attention to the sensory experience of those objects is a subtle one; so the former is apt to substitute for the latter.  Even when experience isn’t so easily traceable to an outside object, I’m inclined to think our theories can profoundly affect our reports.  If we think images must be like pictures, we’re more apt to instill reports of imagery with picture-like qualities than if we don’t hold that view.  If we think cognition takes place in the brain, we’re more apt to locate our cognitive phenomenology there than if we think it takes place in the heart.  If we think that memories must be imagistic, we’re more apt than those who don’t think so to report memory images.

Experience is a fast-moving chaos -- a tornado whipping through a magnet factory.  If we approach it without practice and skills, with derivative, second-hand concepts, and with our attention split between the experience itself and the act of trying to figure out what that experience is, no wonder we make a mess of it.  We end up describing at least as much what we expect to be there as what is actually there.

Isn't consciousness at some basic level a wysiwyg experience?

Howie said...

Four questions: first, Freud claimed most of our thoughts lie in the unconscious. You'd say we just can't introspect them; second, Wundt tried to develop a technique of introspection. Did he succeed? Third, we're conceivably more aware of other people's thoughts than our own? Finally, can techniques such as meditation boost our introspections?

Arnold said...

What alerted me to be an introspecter, was at 11 yrs old my father saying...
..."your doing half a job when you do your chores"...

Is that a way an inner life begins...

67 years later, is it possible human population at birth is half introspective half extrospective...
...and is the reason for life-to-remember to work to bring these two halves together forever-always...

Howie said...

Can brain conditions such as mental illness and autism alter the ability to introspect, or are certain kinds of people like musicians and artists and poets and novelists better able to introspect in certain domains and circumstances? And do mind altering drugs tamper with introspection?

Professor,
Note that your three explanations for why we’re bad at introspection went to five, and I’d think you could come up with more if you tried.

It would seem that we need broad theory which addresses such issues in general. That should be achieved if/when science gains an experimentally successful model regarding the nature of what you and I call “consciousness”. (Here I mean your example based position from the video, or more comprehensively your “innocent” response to illusionists.)

Just as a lightbulb may produce light rather than exist as such, consider the possibility that the brain never exists as subjective experience though does often produce it. And I do mean this literally — I personally suspect that consciousness exists as a standing electromagnetic wave produced by the proper sort of synchronous neuron firing. In this wave a strange serial computer seems to function by means of a brain’s vast parallel computational function. I suspect that experimentally successful theory will address the five ways that you’ve noted us to be bad at introspection, and beyond.

For example, 1) why is experience fleeting and changeable?

Perhaps because experience exists as running input to a constantly changing electromagnetic wave? I consider the purpose of this experiencer to feel as good as it possibly can each moment, and tempered by memories of its past, as well as hopes and worries about its future.

In any case, just as Newton and Einstein have helped us in many ways grasp “gravity”, science should ultimately provide us with an experimentally successful perspective regarding subjectivity. Though the challenges we face today do seem daunting, foundational work such as yours should help.

Thanks for the comments, all!

Jim: Ah, but what *do* you see?

Howie: 1. Yes. 2. Maybe a little (see my 2004 paper on introspective training). 3. Sometimes! 4. The empirical evidence is still unsettled on this question, but maybe.

Arnold: My guess is that few people are truly introspective.

Howie 2: Yes, yes, and yes. On mind-altering drugs, see my discussion of Oliver Sacks and the difference between phenomenal and doxastic hallucinations.

Phil E: Yes, I agree that it would all be much clearer with a good theory! I hope you'll forgive me for being skeptical of your theory. I am skeptical of all general theories of consciousness. I just think we aren't in a good epistemic position to evaluate them, at least for the medium-term future. (See my paper on garden snails.)

Arnold said...

If this is a continuing topic...

Then today, introspection may be just a matter of teaching and learning about being here now, on this planet, for the possibility of an educated inner life facing evolution's processes...

Philosophy biology physiology psychology, physics consciousness faiths reasons, all senses and traditional ways of living make sense if seen as help for being here now...

Being here now is always changing and seems some kind of apprenticeship/relationship with...a self?...

Jim Cross said...

Eric,

I was being slightly facetious; however, regarding what "do" I see?

I can't tell you but I know it's mine.

Philosopher Eric said...

Well of course you’re skeptical of general theories of consciousness professor — we most certainly haven’t been in a good epistemic position to evaluate them. And why is that? Is this not because popular proposals seem to alway be unfalsifiable and to have all sorts of ridiculous implications? I suspect that I enjoy lampooning such proposals no less than you do.

For a change of pace however, I know of a proposal that isn’t popular, doesn’t seem to have any ridiculous implications, and even seems quite testable with standard technology. I’m referring to Johnjoe McFadden’s cemi field theory.

For anyone who hasn’t read about it (and since you’re in the business professor, I presume that you have), it’s well known that when neurons fire they create tiny electromagnetic disturbances, or the very thing that we detect to presume neuron firing itself. Furthermore the synchronous neuron firing which is documented to correlate with conscious experience should tend to create a stronger type of EM field given the combined energies. McFadden proposes that the subjective experience which each of us are currently having might exist as an amazingly complex EM wave created by certain varieties of synchronously fired neurons. He summarizes this position and provides his associated papers here.

Now for the revolutionary part. It seems to me that all we’d need to test his theory is to see if we could reliably alter the EM field that he proposes as consciousness, using a transmitter that simulates synchronous neuron firing (and apparently it would need to be implanted in the head given the related physics). Thus a test subject could sit down with researchers and tell them if anything seemed phenomenally strange while countless combinations of synchronous charges were initiated by the transmitter.

At some point McFadden’s theory might effectively be falsified, and so he’d have the privilege of demonstrating how to approach consciousness scientifically rather than popularly. Or conversely a relevant combination might be tried that feels out of place to a test subject, ultimately heralding a truly wondrous paradigm shift. Either way, wouldn’t this be awesome professor?
