Too often, we think of intelligence as a fixed quantity, as if we have a certain amount of a magical substance in our heads, and that amount can not be essentially changed. It's a dangerous, damaging, depressing fallacy, and in my experience, it's one of the greatest obstacles to student learning.
David Shenk nicely debunks this fallacy in a
2009 article for The Atlantic. He argues, rather convincingly, that while our genes may theoretically influence our intelligence, our development is a much larger agent in our problem solving ability. IQ is a measurement of a particular set of skills, and those skills can be improved.
Let's not also forget that the IQ test is intentionally narrow in its measurement. It quantifies a particular kind of problem solving, and it does it well, but it makes no attempt to measure intelligence types that are at least as important.
So the next time your student, your colleague, your family member says he's "not smart" or is "bad at that," it might help to remind him that his disposition toward himself or to the subject is much more predictive of his success than the jar of quicksilver ability he believes has been doled out to him by his genes or his creator.
It's not his fault, of course. Western society (and probably others) is absolutely replete with institutional and cultural building blocks that encourage us to think of our abilities as fixed and immovable. Impressive people have "genius;" struggling students are "weak." We separate kids by abilities early in their lives, and we might even refer to some of them as "gifted," as if the others didn't receive the gene as their first birthday present.
This mindset both encourages mediocrity and devalues achievement. A student who demonstrates brilliance in a paper has brought a lifetime of dispositions, opportunities, choices, and yes, talents. But let us not confuse a knack that allows a student to progress quickly for an irreproducible gift that the student has received through some genetic sorcery.
"But," you say, "I have students who work incredibly hard who don't make as much progress as students who do less work. Is that not proof of the existence of talent, raw intelligence, and a gift?" Maybe, and I don't claim to understand every aspect of the interaction between genes, brains, and choices. There probably are starting lines drawn in some ways in our abilities. But I'm also willing to bet dollars to donuts that your hardworking student also has limiting dispositions in his work and that your lessworking student has advantages that have little to do with raw intelligence.
What we mistake for a static gift is actually a combination for factors, the majority of which we
can change, and we
can influence. Your student has a measurable IQ, but the question isn't "what's your IQ?" The question is "what are you doing to raise it?"
