Heuristics That Almost Always Work An Article by Scott Alexander astralcodexten.substack.com Sometimes there’s a Heuristic That Almost Always Works, like “this technology won’t change everything” or “there won’t be a hurricane tomorrow”. And sometimes the rare exceptions are so important to spot that we charge experts with the task. But the heuristics are so hard to beat that the experts themselves might be tempted to secretly rely on them, while publicly pretending to use more subtle forms of expertise. …Maybe this is because the experts are stupid and lazy. Or maybe it’s social pressure: failure because you didn’t follow a well-known heuristic that even a rock can get right is more humiliating than failure because you didn’t predict a subtle phenomenon that nobody else predicted either. Or maybe it’s because false positives are more common (albeit less important) than false negatives, and so over any “reasonable” timescale the people who never give false positives look more accurate and get selected for. expertiseheuristicsprediction
Beauty and compression An Article by Scott Alexander astralcodexten.substack.com The Buddha discusses states of extreme bliss attainable through meditation: Secluded from sensual pleasures, secluded from unwholesome states, a bhikkhu enters and dwells in the first jhāna, which is accompanied by thought and examination, with rapture and happiness born of seclusion. ...If you could really concentrate on a metronome, it would be more blissful than a symphony. The jhāna is also a strong contender as a theory of beauty: beauty is that which is compressible but has not already been compressed. The Abode of the Unsymmetrical beautysilencesensesattention

Why Keep a Field Notebook? An Essay from Field Notes on Science and Nature by Erick Greene Pick one thingLab notebooksHybrid journalsA fertile incubatorBest practices
Pick one thing I recently started a field notebook assignment for my upper-level Ecology class at the University of Montana. I asked my students to pick one “thing” and observe it carefully over the entire semester. In addition to their field notebooks, the students also had to suggest at least ten research questions inspired by their observations. One brick seeing
Lab notebooks Most of my colleagues who conduct laboratory research not only keep extremely thorough and complete lab notebooks, but they teach their students how and why to keep data in them. Some labs even have friendly competitions in which prizes for the best-kept notebooks are awarded. In stark contrast to the vibrant culture of keeping lab notebooks in molecular biology, my informal polling suggested a lack of interest in notebooks in field biology. “I have a GPS for that.” “My data are in a spreadsheet.” “I write things down when I get home.” “I have a computer.” The general consensus seemed to be that field notebooks are quaint, archaic, and obsolete in field biology.
Hybrid journals The most useful and interesting notebooks of field biology are hybrids; as well as recording details and data of field research, they record the observations, thoughts, musings, and peregrinations of the author. notetaking
A fertile incubator Another value of field notebooks is their ability to serve as an incredibly fertile incubator for your ideas and observations. By jotting down interesting observations, questions, and miscellaneous ideas, your field notebook can serve as a powerful catalyst for new experiments and projects. notetaking
Best practices Use a hardbound notebook. Keep your contact information in a prominent location. Write for yourself and for posterity. Write pertinent field information with every new entry. You should enter the date, time, and location at the top of every page. Add information on your location. Record your methods. Make backup copies. If you use abbreviations, make sure there is a key in your field notebook. Don’t leave home without it. Form a writing habit. Thomas Jefferson was such an inveterate chronicler of daily events in his notebooks that he even took the time to record the weather four times on the day he helped write the Declaration of Independence. So unless you have something far more pressing than writing the Declaration of Independence, you have no excuse for avoiding your field notebook! Set up a structure for your field notebook. Create an index. Treat your field notebook like a scrapbook. You should view your field notebook as a central clearinghouse for miscellaneous information that is relevant to your research project. If there are related bits of information that you will find useful later on, sketch them, write them down, photocopy them, and staple or tape them in your notebook. Five basic rules indexes
