Book Review: "Whistling Vivaldi" by Claude Steele

Last year, Princeton University recommended that the incoming students in the class of 2019, as well as any and all other members, read the book Whistling Vivaldi by Claude M. Steele. I learned at that time that it was a study about the biases we carry and the way society's collective biases can affect us in different situations (along with what corrective actions can be taken with respect to those biases), so it seemed pretty interesting at that time. My interest was further piqued by seeing that my advisor was reading it then too, so I figured I should read it at some point. Classes and (later) preparing for my general examination got in the way, so I didn't really have a chance to read through it until now. Having read through it, I'm writing a short review below (my first formal book review for this blog in a long time), consisting of a summary (that is probably going to be incomplete) as well as some longer questions after the jump. At this point, I should say as a reminder that I am a physicist, not a sociologist/psychologist/anthropologist, so a lot of the questions or remarks that I make will probably be easy to refute with current research in the field; given that it isn't my specialty (so I wouldn't necessarily know how to go about it), and in the interest of starting a conversation, I would like to invite you, the reader, to respond to these issues in the comments below.

The book is written by a psychologist, and focuses on a series of controlled experiments designed to understand the role that societal biases (regarding group identities, such as race and gender) have on people's performance in situations where their presence may or may not be socially expected (e.g. women versus men in STEM fields, or white versus black people in professional basketball). These experiments have been replicated in a variety of settings and seem to show fairly consistently that especially among people who would otherwise be expected (based on prior experiences, such as test scores or basketball performance in high school) to perform well in a field where their group is not well-represented, being aware (generally through life experience, or explicitly in the course of a test in that field) of their group identity can negatively impact their performance, because their minds are subconsciously consumed by the stress of trying to consciously break the stereotype of poor performance in that field by other people in their group, to the extent that this rumination hinders their ability to focus on the task at hand and causes them to perform worse than people in a more fully represented group; by contrast, people in an underrepresented group who are told that their performance isn't meant to be judged as diagnostic of their ability, or who are otherwise convinced that past stereotypes are irrelevant to the test at hand, do just as well as people in a more fully represented group (whose members do not generally see a performance boost from such a treatment). These experiments are fleshed out to a fuller extent over the course of the book, looking at different instances of stereotype threats in different situations, and looking at different metrics (including physiological ones, like blood pressure or heartbeat patterns) for measuring the impact of stereotype threats on performance. As the author offers several lessons throughout the book on what can be done to counter stereotype threat issues, the book closes with a summary of what works under different broad circumstances, and what further issues need to be faced.

There are a few issues that I have with the book overall. One is that the "introduction" of various people (mostly academic collaborators, students, and others in academia) that the author has met seems extraneous. The sense I got was that he wanted the reader to feel personally engaged with the details of the author's academic life, but by giving only cursory importance to these meetings (and then, only to set up descriptions of the experiments they ran), his writing on this matter came out rather stilted in the end. Thankfully, the book itself is fairly short (only 220 pages), so this is less of a problem. The two bigger problems that I have follow. The first of these problems is that in the middle of the book, the author introduces the story of a man named John Henry Martin, born in the early twentieth century, who eventually freed himself from sharecropping servitude and worked incredibly hard to better his lot, though he paid a steep price in doing so (in the form of much worse health and shortened lifespan). This anecdote is used to demonstrate how a great work ethic in conjunction with terrible struggles against difficult circumstances can generally adversely impact a person's life. However, though the chapter ends not too far after that, the remainder of the chapter essentially engages in idle speculation about whether previous examples of people struggling under stereotype threats would have suffered in deeper ways if the stereotype threats were chronic (rather than short-term/acute). Not only was I confused and lost in that short section, but that whole passage seemed rather disconnected from what came before and after. As far as going into the effects of chronic stereotype threats, what comes before is sufficient, and a smoother transition to what comes after would be all that is needed. The second of these problems is that throughout the book, the author tries to use a mix of anecdotes and general descriptions of studies and their results to engage a general audience. The issue I have is that either the anecdotes should be made more compelling to justify the qualitatively-described studies, or the studies should be described more quantitatively to justify the brief anecdotes that precede them; the author tries to be a too clever in splitting the difference, but the end result feels a bit less meaty than I'd like. (As a matter of personal preference, given my expectations of what a description of controlled studies should have, I would prefer that the book feature a level of quantitative description similar to One Nation, Underprivileged by Mark Robert Rank (which I read about a year ago).)

Despite these reservations, I did enjoy reading the book, as it opened my eyes not necessarily to biases per se, but to the ways that biases can affect people's performance (as well as how people affected by these biases view and respond to them). It certainly got me thinking about some of the other ways that biases and stereotype threats can cut. With that in mind, follow the jump to see some questions that I have about the book, and please do respond in the comments with thoughts of your own (especially if you have citations for more recent research that could answer some of my naive questions).

Generals Impending

I briefly thought of doing a review or another longer post this month, but I realized that studying for my generals will require too much of my time and concentration to allow for that. Instead, I'll keep this post as an update about my upcoming generals. My generals will have two parts: the first is a standard research seminar where I get to talk about some of the stuff that I've done over the last year and more, while the second is an oral exam where the three committee members get to ask me more fundamental questions. The oral exam is tricky to prepare for because those questions could in principle be about anything; that said, from what I understand, the committee members tend to ask about things related to my research topics, my coursework, or other basic things that they expect someone in my field to understand, so I basically have to study a broad range of material and hope for the best. The research seminar is a little better, because I have a better sense of my own research than at least two out of the three committee members (the excluded member being my advisor); I just have to make sure that I know what I'm talking about (and on that same note that I don't start making stuff up), so this will require me to go a little broad but more deep into the fundamentals underlying my research.

I said in a post from two months ago that I'm working on projects involving nanoscale wetting as well as more accurate modeling of the optical response of electrons in nanoscale metal structures. Right now, I'm not so sure about the future of the second project, because there still seems to be a lot of controversy about how to properly account for boundary effects in finite metal systems, and our group is not really in the business of making those [more fundamental] decisions; instead, we'd like to use a more well-established model of optical response and hope to show some new and interesting results using novel techniques in computational electromagnetics. Given that, my research seminar is almost exclusively going to focus on the first project, which is a much better-posed and better-developed problem and has consequently led to very interesting results. (I can't really give more details until we put out a publication.)

Anyway, at this point I'm waiting to be over with generals, while studying hard for them as the days count down. I promise that I'll have a more typical post next month, after I finish both parts of generals.

Research and Generals

I was intending to post a review this month, but I got too busy and didn't have the time to do that. Instead, I'll keep this as a short update. Right now, I'm quite occupied with doing research on two projects: one has to do with wetting at the nanoscale, and the other has to do with modeling the optical response of electrons in metals and semiconductors. They may seem divorced from each other at first, but they are both electromagnetic phenomena, and if I consider Casimir forces or heat transfer from metals or semiconductors, they both involve fluctuational phenomena as well. Concurrently with research, I am preparing for my general examinations (often called qualifying examinations elsewhere) which are coming up in April or May. Anyway, hopefully I'll have a little time next month to put a review or another sort of post like that out.

On Transitioning into Graduate Life, One Year In

This is a post that's more about what's going on in my life right now, so if you would have liked to see a software review or an otherwise more technical/generally topical post, fear not! That shall come in at least one more post this month. This post is more about some thoughts I've had about mentally and socially transitioning to life in graduate school after a little over a year in it, so I just hope that anyone going through a similar transition may find this even mildly interesting. Follow the jump to see more.

Thesis and Papers and Projects, Oh My!

I realize I haven't been able to post anything in...a month, actually. That's because most of my time has recently been devoted to finishing my undergraduate thesis (due in 1.5 weeks), 2 final projects (due in 2.5 weeks), the work for a potential paper for my UROP (hopefully soon), problem sets (all the time), and exams (sporadically, though thankfully I have no final exams). I hope to have more posts (including a few reviews) out in the coming weeks when I'm a little more free. In the meantime, enjoy this nugget of crazy physics: apparently it's possible to derive asymptotic freedom in QCD from classical statistical field theory.

Done with 3rd Semester!

I'm finally done with my 3rd semester! Yay! Although this semester I was just taking the classes for my major/that I wanted to take, thanks to the combination of 4 classes (all of which have problem sets and exams), a UROP, and grading, this semester was way more grueling than any previous semester. Thankfully, I think I've done fine, so I feel like I would be better prepared to do the same (4 classes, a UROP, and grading) next semester.
But before I need to worry about next semester or even IAP, I get to go home for winter break! Woohoo!

Done with 2nd Semester!

Today is my last day of my second semester at MIT, and that also marks the completion of my freshman year in college. Woohoo! I can finally relax for a few days. Finally.
Of course, that's only going to be for a few days, because next Monday I start my internship at NIST, and that'll be for 10-12 weeks. I'm excited about that too.
This semester was definitely harder than last semester, which is why I'm so much happier that I'm done with it now. Part of that is because the classes I took this semester were harder than the ones I took last semester. Part of that is because I enjoyed the classes last semester more than I did the classes this semester. And part of that is because of the pressure of grades; last semester was Pass/No Record, while this semester has been A/B/C/No Record.
If you're in school or college, how did you feel about this semester/academic term and/or academic year? Do you have any plans for the summer? Let me know in the comments below!

Done with 1st Semester!

Yay! I'm done with my first semester here at MIT! Overall, final exams worked out pretty well.
I'm going back home either tomorrow or the day after that. When I do, I'll be able to spend more time with loved ones and more time relaxing (and writing here).
For those people in school/college, how did your term go?
