The book developed as a fusion of this resource collection with real-life observations. A few of the more notable observations related to generational perceptions, learning strategies, reputation management, trainee perceptions, and impact on well-being. When I began the project, I had become convinced that there were true, dramatic generational changes amongst trainees compared to a decade or two before. I first heard of a massive generational shift in commitment a couple years out of training. At first, I thought it was folklore. After a few more years, however, I became convinced it was true. It certainly seemed, as was said, that there was widespread evidence in various programs that many trainees stopped reading and studying, drew boundaries from work and home life so sharp that they never check messages or do non-mandatory work off hours. There seemed to be less commitment, more entitlement, and too much emphasis on lifestyle than career. I had some compelling personal experiences that strongly reinforced these beliefs too. But it is far more than that. Most of the stories and perceptions I have heard from staff from many locations cannot be repeated. Suffice it to say, the message was always similar. In my day, we had it together. I would have NEVER left before an attending at the end of the day. It’s like they don’t care about what I have to teach them or about the patients. The resident asked to leave early to service their car, bring their pet to a routine vet appointment, to make their Pilates class. If they want to clock out every day at 4pm on the dot, they should work in fast food instead. Generational shifts had also been popularized by things like the book Generation Me: Why Today’s Young Americans Are More Confident, Assertive, Entitled – and More Miserable Than Ever Before. But were dramatic generational shifts fact or fiction? Certainly, some things were changing. More online videos and Anki Cards, which have partly (and sometimes entirely) replaced more comprehensive book reading. There was more vacation and time off, involuntary as it was. Grades and even board scores have migrated to pass-fail paradigms. Some medical students attend pre-clinical classes virtually. There were quantum leaps in technology. There may be shifting life priorities too. The word ‘calling’ shifted from something noble to something abusive (in reality, it can be both, although I’d like to favor the former. We also can’t deny potential effects from the 2020 pandemic. In the book, I describe the firing of a longtime-lauded organic chemistry professor, Maitland Jones, from New York University in 2002 because students protested that his exams and teaching methods, used for decades, were considered too hard. Some experts refute certain claims from Generation Me. Elders have lamented the younger generation since at least the time of the ancient Greeks. A 22-year veteran teacher, Vernon, laments that “each year, these kids get more and more arrogant” in the 1985 move The Breakfast Club. Abe Simpson, in 2002 (season 13, episode 19) of The Simpsons, declared that “every generation stinks but ours.” Generational labels have become controversial and are thought to be due, at least in part, due to the illusion of moral decline, a false renewing belief that morality has declined in the younger generations. In response to research supporting the view that generational differences are largely due to labels and biases, the Pew Research Center decided to end categorization by generation unless absolutely needed in May 2023. Whatever the truth, I have now adopted a more middle-ground view. I think there are natural differences that reflect different circumstances and some of these are naturally frustrating to attendings, but younger people today are fundamentally the same as younger people always have been. However, even if the generational shifts are exaggerated, the perception is real and creates substantial challenges for medical trainees. Reflecting on generational changes and learning, regardless of whether trainees these days are using more effective or less effective learning resources than we did in the past, the amount of information they need to learn and apply in the real world is vast and usually requires a pivot in learning strategy compared to pre-medical years. I believe that most trainees could benefit from more direction in the application of learning strategies. While videos and flashcards, when done well, can be quite effective, they can easily become passive, and ineffective. In other words, short-cuts. Short-cut learning methods can lead to noticeable knowledge gaps and challenges applying information to real-life cases to arrive at a diagnosis and formulate a coherent impression and plan. One area of feedback I hear is that this higher-order application of knowledge needs work. Since finding effective learning methods can be a major challenge for trainees at the intersection of the formal and hidden curricula, the topic features prominently in the book with separate sections focused on pre-clinical and clinical experiences. Most of the content is evidence-based, and there is lots of evidence on the topic that medical trainees often are unaware of, but also touch on my personal experience as well, including methods to learn cross-sectional anatomy and to prioritize information. Another theme I try to convey is the need to be proactive, actively involved, and work to help your team function smoothly in clinical rotations. You don’t want to overstep your boundaries or show dangerous overconfidence, but if you wait to be invited to participate too much, you are putting yourself at a disadvantage. This means you must navigate the challenge between balancing the learning/student and attending identity mindset and work towards feeling responsible and thinking like an attending. I’ve noticed that some trainees stay too far to the side of a student or observational mindset for too long. Another topic that is important to me, and I think most trainees, is well-being. Here, I try to convey that the topic can be viewed as a double-edged sword. Despite increased formal focus on trainee well-being with time off, wellness days, questions on staff surveys, and so on, it seems to me that many of the fundamental forces that impede well-being remain an under-recognized problem. These forces are many and include: mixed messages about the importance of exercise, diet, and sleep; tacit prioritization of medical care over preventative lifestyle measures (for patients and, by extensive, us); financial challenges with little financial education; and burnout that may be exacerbated by the energy it takes to navigate the hidden curriculum. The viewpoints and potential biases of trainee generations, including what they prioritize in the personal and professional lives, how they learn, and so on can set the baseline viewpoint of attendings, often not in your favor. In addition, vast data shows that first impressions matter a lot and induce biases that color future perceptions. This is, in part, a heuristic, we tend to use to create a coherent narrative to explain why those around us act they way they do. The problem is that we rely on this heuristic too much, creating what is called excessive coherence. First impressions are even more important when attendings might harbor baseline generational biases. Furthermore, initial impressions are often passed on from staff to staff by word-of-mouth, which further colors others’ viewpoints. Therefore, first impressions such as arriving on the first day of a rotation on time, prepared, and enthusiastic are probably more important than most people realize. In the book, we further consider these cascade effects, which can sometimes evolve into a butterfly effect. Such biased and subjective evaluations can become problematic. In fact, subjective performance-based evaluations are generally about 25% signal and 75% noise according to Kahneman et al. in Noise. Data also points to low reliability of subjective ratings specifically in medical training. Since these flawed evaluations will be amongst the important that you will ever receive, it is useful to try to tilt the odds in your favor. In my experience, it is common to receive polar opposite evaluations of the same trainee on the same rotation by different attendings; one might say she’s one of the best residents we’ve had in a while another expresses grave concerns. I’ve also noticed that trainees’ ability to predict how easy a grader is based on their daily interactions is quite poor. Some attendings who might seem like best buds are the toughest and sometimes an old curmudgeon just wants you to succeed and offers glowing written evaluations. Thus, the importance of discerning the true expectations of your evaluators beyond the formal metrics, is crucial. For this reason, seeking out these expectations, seeking feedback, and responding well to feedback are prominent topics. And this is just the start. Many other critical topics are covered too and almost all of it is material that is not spelled out often enough in medical training. The good news is that managing a lot of it is easy. The theoretically easy-to-fix things like lapses in professionalism, asking to leave too early, perceived violations of the hierarchy, and the like are where trainees often stumble. Additionally, it is true that success is 25% inspiration and 75% perspiration. In medical training perspiration is working smartly and consistently. This is a whole lot easier when you’ve set up your life to facilitate productivity and have developed healthy habits upfront. Now, some of it’s hard too of course. Effective learning is effortful and active. Some things like dealing with high emotions, difficult personalities, failure, and negative feedback can be very difficult and even unnatural.
