Collective Intelligence

Notes by Howard Gardner

Especially for those of us interested in collaboration (see Good Collaboration at www.thegoodproject.org), the idea of a collective intelligence is intriguing. It is important to know, empirically, at what tasks groups working together perform well, and why they do so. And in an era where connection is easy to initiate and virtually ubiquitous, it’s important to know which forms of collaboration are most effective.

In this article, my colleague Tom Malone takes a popular view that intelligence is singular, of a piece. And indeed, to the extent that he uses standard problem solving puzzles (e.g. cross puzzles or mental arithmetic), he is basically speaking about linguistic and logical-mathematical intelligences, the forms routinely measured on IQ tests.

However, Malone also notes that the groups need members who can understand one another and who do not dominate the conversation. In making these references, he is effectively ‘smuggling in’ interpersonal and intrapersonal intelligences. Moreover, if he were to broaden the set of tasks posed for a group; for example, recognition of artistic styles, or discriminating among kinds of animals, or creating memorable tunes, he might well find that other human intelligences prove to be at a premium.

The Brain Trainers

Notes by Howard Gardner

We are well advised to be skeptical of claims, particularly on the part of commercial enterprises, that they have accomplished educational miracles. Were this the case, we’d all be geniuses! In fact, genuine educational miracles take place over decades, even centuries; not through some kind of training that unfolds over a matter of weeks.

That said, there’s little question that we can benefit from some kinds of brief training, whether in physical fitness, diet, or some kind of self-control, as in the exercises described here. Of course, we have to keep up the training. And we know that the major purchasers of diet books are those who have failed on numerous previous regimens.

But even if so-called ‘brain training’ proves effective, we need to determine the limits of the training. Even the strongest advocate would not claim, for example, that such training makes you more ethical or more beautiful! As I read this study, I agreed with Douglas Detterman. Probably these trainings help you to do better at certain kinds of tests, maybe even including certain kinds of IQ tests. And if you have never had that kind of training, it is valuable and legitimate to obtain it. Indeed, that is the contribution of the Israeli psychologist, Reuven Feuerstein, whom I much admire. But whether the exercises equip you to be more effective at the workplace, or to make more sense of the world, is doubtful in the extreme.

Intelligence and Genetics

Notes by Howard Gardner

By an interesting coincidence, the definition of genes, and the measurement of intelligence, both entered human civilization at about the same time. In the first decade of the 20th century, British scientist William Bateson first developed the science of genetics and the notion of a gene; and at the same time, the French psychologist and educator Alfred Binet devised the first psychological tests of intelligence.

Dating back almost to that time, scientists and other commentators have speculated about the genetics of intelligence. This speculation has taken two forms: 1) To what extent is our intelligence inherited from our parents/grandparents? 2) Can we specify the gene(s) that are responsible for/mediate our psychometric intelligence?

Experts differ greatly on the question of the heritability of intelligence. In my own work, I have always assumed that each intelligence has a heritable component but we are far from knowing the extent of heritability of each of the several intelligences.

As this article indicates, there have been many claims to have discovered the gene, or the small set of genes, that determine our psychometric intelligence. The study, emanating from several of the leading scholars in the field, sounds a skeptical note. Based on 10,000 subjects examined in three independent studies, the scholars document their failure to find a significantly positive connection between candidate genes and IQ.

Of course, many conclusions can be drawn from this negative result. I am sure that many scientists, including the authors of this report, will continue to look; and eventually, psychometric intelligence, like almost every other human trait, will turn out both to be heritable and to be linked to certain genes. My own view is that we are more likely to find the genetic bases for various components of the several intelligences; and that the extent to which, and the ways in which, those genetic potentials are expressed will depend heavily on the norms and models in the ambient culture.

A Shift in Perception

Notes by Howard Gardner

Nearly all of us have acuity in several sensory systems, and most of us are capable of making some cross-sensory connections (e.g. between loud sound and bright light). When we are young, many of us have a proclivity to synesthesia; for example, connecting colors to the sounds of vowels or to the timbre of musical instruments. This capacity tends to atrophy with development, except for the few who have the capacity called synesthesia. Sometimes synesthesia can get in the way of normal processing; sometimes it can contribute to creative work, as with the Russian composer Alexander Scriabin or the novelist Vladimir Nabokov; and sometimes it is just a strange fear—like knowing the days of the week on which major holidays occurred in 1875.

I have long maintained that the multiple intelligences are not yoked to particular senses. Linguistic intelligence can operate independent of whether information enters the ‘central cognitive system’ via sound, sight, or touch. It’s therefore an open question whether we can have synesthesia across intelligences, as we do across sensory systems. Such synesthesia would, for example, yoke linguistic and spatial information, independent of the channels by which this information entered the cognitive system. I do not have a strong intuition about the answer to this question; indeed, this would be a fascinating topic for a young researcher to investigate.

IQ Tests Hurt Kids, Schools

This article provides documentation that different intelligence tests yield different scores for the same person.  Even more intriguingly, even the same intelligence test, administered multiple times, may yield different scores. The article also and appropriately underscores the importance, in life, of non-cognitive skills, or skills that do not fall comfortably under the IQ measurement.

That said, as I read it, Kaufman still holds onto the hope that, someday, if we are clever enough, we will be able to provide an ultimate and fully reliable and valid test of intelligence. I am skeptical about this. What we value as individuals and as a society changes; and so do the resources and contexts of life also change. And so, in my view, intelligence, or more properly, intelligences, are a moving target. A search for the Ultimate IQ test is like the search for a Fountain of Youth; it may be motivating but it is doomed to fail.
