Background and Context
This maxim was collected October 26, 2018, one of three "Rules of Good Instructional Design" filed within roughly half an hour of each other — the Second Rule a minute earlier, the Third about twenty-seven minutes later. Together they read as a single sitting's worth of accumulated professional irritation, compressed into numbered form. The First Rule stakes out the most basic and least glamorous claim of the set: before a designer worries about learning objectives, engagement strategies, or instructional theory, the words on the page have to be correct. It targets a failure mode any working instructional designer has watched happen — a course, deck, or job aid that gets the pedagogy right and the prose wrong, and loses the room anyway.
Interpretation
The maxim's structure is a simple conditional dressed up as a command: do this, or else. "Always proofread and check your grammar" is the imperative; "otherwise, you may look like an idiot" is the stake. What makes the line worth reading closely is what the stake is — not "otherwise the training will fail" or "otherwise learners will be confused," but a claim about how the author is perceived. This is a maxim about credibility, not comprehension. A typo doesn't usually stop a reader from following the material; it stops them from trusting the person who made it. The mechanism is instant and largely unconscious: a stray "your" for "you're," a missing verb, a garbled sentence, and the reader's attention swerves from the content to the competence of whoever produced it. Once that swerve happens, everything else in the document has to work harder to earn back the credibility the error just spent.
The word "idiot" is doing more work than its bluntness suggests. Mike's maxim collection reaches for it elsewhere — in "Mike on Incompetence" and "Mike on the Pharisees of Education" — as a recurring marker for a specific kind of failure: not a lack of intelligence, but a lack of care in exactly the place where care was cheap to supply. Proofreading is not a hard skill. It requires no special training, no deep domain expertise, no creative risk — only the discipline of a second pass before calling something finished. That is precisely what makes an uncaught error so damaging to credibility: an audience can forgive a design choice they disagree with, because disagreement implies the designer thought about it. They extend much less patience to a mistake that implies the designer didn't — that the material went out the door without anyone checking it. The maxim's harshness is calibrated to that distinction: it is not punishing difficulty, it is punishing carelessness.
Read against its siblings, the First Rule also does quiet structural work for the set. The Second Rule ("don't repeat assignment instructions in more than one place") and the Third Rule ("good context is key") both operate at the level of structure — how information is organized so it stays correct and legible over time. The First Rule operates one level below structure, at the level of surface — whether the individual sentence is correct at all. A perfectly structured course built on ungrammatical, typo-riddled prose still fails, because the reader's trust breaks before they ever get far enough to notice the structure was sound. In that sense the First Rule functions as a gate the other two rules assume has already been passed.
Current Relevance
The maxim's stakes have shifted, not diminished, since 2018. Generative AI drafting and autocomplete tools have made it trivially fast to produce large volumes of training text, and correspondingly easy to publish material nobody actually read closely — spell-check catches misspellings but not wrong words used correctly ("their" for "there," "affect" for "effect"), and an AI-drafted paragraph can be grammatically smooth while still containing a factual or logical error a human proofreader would have caught precisely because fluent phrasing lowers the reader's guard rather than raising it. The maxim's underlying claim — that a careless error costs credibility disproportionate to its size — applies with equal or greater force to AI-assisted output, where the volume of unreviewed text a single person can generate has grown even as the habit of a deliberate second pass has, for many, gotten easier to skip. A course built from an AI-drafted outline can look polished at a glance and still carry the exact failure this maxim warns against: nobody actually read it closely before it shipped.
The same dynamic shows up in workplace communication broadly: a hiring manager who tosses a resume with a typo without reading the rest of it, an executive who loses confidence in a funding proposal after one glaring grammatical slip in the first paragraph, a learner who assumes a course with sloppy captions or misspelled slide titles was built just as sloppily underneath, regardless of how sound the actual instructional design is. The maxim's real claim — that surface-level care functions as a visible proxy for care the audience can't directly observe — generalizes well past instructional design, into any context where a reader has no way to verify the quality of unseen work except by judging the quality of what's actually in front of them. Remote and asynchronous work has, if anything, raised the stakes further: a Slack message, an onboarding doc, or a recorded training module is often the only interaction a colleague or learner has with the person who made it, so the surface is doing more evidentiary work, not less, than it did when errors could be caught and corrected in a live room.
Impact and Legacy
As a private aphorism rather than a published statement, the First Rule's legacy lives inside the small numbered set it belongs to and the broader maxim folder around it, rather than in any public discourse it shaped. Read alongside the Second Rule ("don't repeat assignment instructions in more than one place") and the Third Rule ("good context is key"), it establishes the floor the other two build on — structure and context matter, but only once the material clears the more basic bar of being correctly written in the first place. A course can honor the Second and Third Rules perfectly, with instructions stated once and context supplied clearly, and still fail on the First if the actual sentences are riddled with errors; the ordering is not incidental, it names the most basic and least skippable requirement first. Within Mike's wider collection, it sits comfortably beside "Mike on Incompetence" and "Mike on the Pharisees of Education" as one more entry in a running personal taxonomy of avoidable professional failure — not a treatise on grammar, but a field note, numbered "First" for a reason, on what erodes trust fastest and costs least to prevent. Its influence, such as it is, is entirely local: a private standard applied to Mike's own work and, presumably, to the work he reviewed, rather than a principle argued publicly or adopted by name elsewhere. That narrowness is itself informative — the maxim was never meant to travel beyond the practical context that produced it, and its durability is measured by whether it still holds up as a working rule of thumb decades later, not by any wider circulation.
Contrasting Views or Controversies
The maxim's clearest limitation is its flattening of severity. Not every grammatical slip carries the same weight, and treating a minor typo with the same rhetorical force as a genuinely confusing sentence risks a kind of perfectionism that mistakes surface polish for substance. A course that is grammatically flawless but pedagogically empty serves learners worse than one with an occasional stray comma and a well-designed learning path — the maxim, taken too literally, could reward the wrong kind of diligence.
There is also a real tension between this maxim and speed. Instructional design frequently operates under deadline pressure where a rapid, imperfect draft that ships on time serves an organization better than a polished one that ships late — the "perfect is the enemy of good" objection applies here as it does anywhere craft meets a calendar. The maxim offers no guidance on how much proofreading is enough, or how to weigh polish against timeliness when the two genuinely conflict, which leaves it more useful as a general disposition than as a decision rule for any specific deadline crunch.
A third objection concerns whose errors get noticed and judged harshly. Grammar and usage norms carry class, education, and dialect markers that are not evenly distributed, and "you may look like an idiot" risks importing a narrower standard of correctness than the maxim's author likely intends — a nonnative English speaker or a writer from a nonstandard dialect background can produce perfectly clear, well-reasoned instructional material that a strict grammatical read would still flag, while a native speaker's fluent-but-shallow prose sails through unchallenged. The maxim is best read as targeting carelessness — the second pass that was skipped, the sentence nobody reread before it shipped — rather than variation in a writer's natural register or accent-inflected phrasing, but the line itself doesn't draw that distinction explicitly, and a literal-minded application of it could penalize the wrong thing: unfamiliarity rather than inattention. A designer applying this rule well has to proofread for actual clarity and error, not police a colleague's writing toward a single dialect's idea of "correct."
Practical Application
- Individual (designer/writer): Build a mandatory second pass into your own process — read the finished draft aloud, print it if the screen has gone stale to your eye, or let it sit overnight before a final check — rather than trusting that a single drafting pass and automated spell-check catch what a deliberately fresh read would. Reading aloud in particular surfaces the errors spell-check misses: a wrong-but-correctly-spelled word, a dropped clause, a sentence that technically parses but doesn't actually say what you meant.
- Individual (reviewer): Treat a document's surface polish as a genuine, if imperfect, signal of care — but separate "this has typos" from "this reasoning is weak" when giving feedback, so a caught grammar error doesn't get mistaken for a verdict on the underlying content, and so a grammatically clean but shallow document doesn't get a pass it hasn't earned on substance.
- Organizational (learning teams): Institute a dedicated proofreading or copy-edit pass, separate from the instructional-design review, before any training material ships — the two kinds of quality (correctness and pedagogy) require different attention and are easy to conflate into a single, less effective review where a reviewer focused on learning objectives simply doesn't notice the typo in the third bullet.
- Organizational (AI-assisted workflows): Treat AI-drafted training content as a first pass requiring the same human proofreading discipline as any other draft, not as a shortcut that exempts the output from review — fluency is not the same guarantee as correctness, and a smooth AI-generated paragraph can still contain a factual error, a broken cross-reference, or a claim that doesn't match the source material.
- Civic/professional (any public-facing writing): Apply the same discipline outside instructional design — a resume, a grant proposal, a public report, a job posting — wherever a reader has no way to verify the work behind the document except by judging the document itself, and where a single visible error can cost the credibility the rest of the document worked to build.
Background on the Author
Mike Hower's collected maxims read as accumulated field notes from a career spent in instructional design, where the gap this maxim names — competent material undercut by an avoidable, visible error — is a routine, practical hazard rather than an abstraction. The First Rule's target on credibility rather than comprehension is consistent with that professional vantage: someone whose work is judged not only on whether learners understood the material, but on whether stakeholders, reviewers, and learners alike trusted that the material had been built with care in the first place, since that trust is what gets a course, a deck, or a job aid a fair reading at all. Filed in the same half-hour sitting as the Second and Third Rules, it reads as the first and most fundamental item in a working checklist assembled from direct, repeated experience of what makes instructional material land — or fail to — the kind of rule that gets written down only after watching a genuinely good idea get dismissed because of how sloppily it arrived on the page. That the three rules were captured together, in one sitting, rather than accumulated one at a time over years, suggests they were prompted by something concrete — a specific project, review, or frustration — even though no note in the file preserves what it was; the maxim reads less like abstract doctrine and more like a lesson paid for once and then written down so it wouldn't have to be paid for twice.
