Believe it or not, there exist people who can skim for key points, make fast mental diagrams, “instantly recognize” what task is being asked, and quickly solve a wide variety of standardized test questions of types they have not explicitly seen before. These people are not superhuman or anything, they just have spent a lot of time doing related kinds of tasks (close reading, competitive debate, code debugging, recreational math problems, etc.) Recreational logic puzzles get
way harder than anything that shows up on the LSAT, and there are students out there who work through books of hard logic puzzles for fun, the way other people might read novels or play video games or whatever.
As an individual, studying for standardized tests isn’t “cheating” or a “bad thing”. It’s often the most rational use of time for folks with specific professional ambitions. But having everyone in the society spend a significant amount of time and stress on a handful of particular standardized tests is IMO a huge waste of collective attention and focus [though perhaps there isn’t any alternative gatekeeping system for law schools which won’t be equally gamed in a time-wasting way]. One problem with the increasing numbers of standardized tests at every level of education is that time spent training for a specific test in e.g. 5th grade has very little long-term benefit for a student.
The standard school curriculum (and frankly a lot of explicit test prep) doesn’t really do a very efficient or effective job of training the kinds of skills that would help someone do well on novel types of standardized test questions. Instead of training reading comprehension, working memory, generic problem solving heuristics, quick recall/matching, problem-solving time management, etc., they tend to focus on the particular features of specific types of problems, and teach memorized recipes or collections of factual information. Obviously this is a reasonable approach if the goals of the training are very narrow and specific. It doesn’t seem to me like the best generic training to do successful intellectual work.
A lot (hundreds if not thousands of papers) has been written about this subject in the scholarly literature by professors who were frustrated that their high-achieving undergraduate {math, physics, engineering, ...} students seem to be able to memorize recipes for solving specific problems very well and ace their usual tests, but have great difficulty synthesizing their knowledge or solving non-standard problems, and then spent some time and effort trying to understand why that is.
