First off, by definition brilliant students don’t slack off; brilliant people might, but that that would make them substandard students.
Putting aside any questions of modesty, false or otherwise, and trying to be objective here, I can say that while far from the smartest guy in the world, I’ve generally been regarded as highly intelligent, and several nominal measures of intelligence would support that assessment. I personally put little stock in standardized tests as a measure of anything other than test-taking ability, but I generally score in the 98th percentile or higher on practically any standardized test I take. I started reading at four years old and read far more widely and deeply than any but a handful of my peers until college.
Throughout elementary school, I excelled academically without expending a whole lot of effort. Partly that was a function of incredibly low standards at the school I attended (in a small town in a very rural part of Arkansas). I attended two different elementary schools in a different part of the state for sixth grade, and for seventh through eleventh grade I was in Fayetteville, Arkansas, the home of the University of Arkansas. In sixth grade, I found myself having to work harder than ever before (I actually made a couple of Bs) and once I moved to Fayetteville the free ride was over for good. I found myself, for the first time, in schools where there were kids as smart or smarter than I was – not just one or two, but several of them – and where the teachers expected much more than in my previous schools. I’d like to claim that I buckled down and thrived academically, but the truth is I resisted, floundered, and had a mediocre junior high and high school career. There were several of us who were, to all appearances, capable of much more academic success than we achieved; primarily, I chalk it up to a combination of:
[ul]
[li] smug, snotty, juvenile false superiority[/li][li] fear of being unmasked as not nearly as smart as we thought we were[/li][li] desire to forge an idenity as outcasts or rebels, and the availability of that niche in the social ecology[/li][li] genuine difficulty in mastering certain subjects without an unaccustomed level of effort[/li][/ul]
Much farther down the list would be such comparatively negligible factors as failure of our teachers to challenge us, resistance to performing assignments we considered pointless (anything that could be considered busywork), teachers who genuinely had it in for one or the other of us (there were a few). Most of us were content with our good grades in the classes that were easy for us and mediocre grades in the rest. We drank a fair amount and did drugs in varying degrees, according to temperament and opportunity (this was the late 70s and early 80s – autre temps, autre moeurs).
Just before my senior year of high school, we moved to another small rural town. I’d taken all of the (nominally) academically challenging classes they offered already, so I ended up in Music Appreciation, American Government, a Spanish I class that was otherwise made up entirely of freshmen, and (God help us) Accounting, just to be able to accumulate enough credits to graduate. A graph of my GPA during this period would resemble the sort of hockey-stick curve usually found only in dot-com business plans of the late 90s. On the strength of that rehabilitated GPA and my extremely high SAT/ACT scores, I had no trouble getting into my first choice of colleges with practically a free ride using mostly merit-based aid.
In college, since I was primarily taking classes that I wanted to take, I did quite well. I could be accused of having slacked off in my required science courses, however; to wit:
[ul]
[li]Elementary Functions (aka pre-calculus): I’d flunked Algebra I once in junior high, barely passed it the second time, and nearly flunked Algebra II in high school (I aced Geometry, on the other hand). I busted my hump for the first few weeks, but a 7:40 am class in my all-time weakest subject during my first quarter of college in a windowless basement room, taught by a Russian emigre professor whose accent was only occasionally comprehensible meant that yours truly was asleep with my head against the wall (we had assigned seats in alphabetical order, and my last name starts with “w”, putting me in the rightmost row, abutting the wall) after the first couple of minutes. Fortunately, the professor graded on a curve, and retained enough of his Russianness that he was determined to finish all of the course material, despite having fallen hopelessly behind after a few weeks. He covered so much material in the last two weeks that in the last test of the quarter, on the final day of class, I scored a 50 out of 100, and on the final exam I had a 55 out of 150. The rest of the class did so poorly, however, that I still pulled a B in the course.[/li][li]Concepts in Physics: a non-majors intro to physics without the labs or the math. I fell asleep in this one nearly every day as well, but kept up in the reading and had little trouble earning a B.[/li][li]Concepts in Biology: another intro course for non-majors. I went into this one with the best of intentions; having put it off until my senior year, and knowing I was outside my usual areas, I resolved to take it seriously and exert myself. I dutifully attended class (five days a week!) and took copious notes, since the professor made a point of saying that there’d be material on the tests that was only in the lectures, not in the book. After the first two weeks, we had our first test. I re-read all the chapters and did the all of the study guide activities and questions in the two nights before the test. Every question on the test was a reworded or slightly altered study guide question. There was absolutely no material that was not in the book. I decided, “hell, I’m a senior, I’ve got better things to do with my time than this.” For the rest of the quarter, I went to class maybe once a week (just often enough to keep up with when the next test would be), read the chapters and did the study guide questions the night before each test, and aced every one of them. Went into the final with mathematical assurance of at least a B in the class, only to have the prof inform us that he wanted everyone to complete the final, but that he was going to drop our lowest test score. This one came back to bite me a few weeks later when the prof turned up on the honors committee; he didn’t appreciate that I’d pretty much given his class a miss all quarter and still aced it.[/ul][/li]
In summary, I’ve known plenty of people whose intelligence was pretty clearly established for me but who didn’t perform very well in school. This is almost always a result of character traits that will hinder success in the working world as well. In my case, I’ve always done well when doing things I enjoy and am interested in and good at, and poorly when doing things that don’t interest me or that are particularly hard for me. I’ve been fortunate in my career that I’ve generally been able to find jobs that I’ve enjoyed and that built on my strengths, and I’ve enjoyed a fifteen-year run of steadily increasing responsibility and income. Right now, however, I’m in my sixth month of unemployment, partly because of the economy and partly because I’ve resisted pursuing some opportunities that I know I wouldn’t enjoy, because I know myself well enough to know that I’d fall on my face.
