Crutch

Podcast 2 — In conversation

Speaker A: She's been on crutches for six weeks now — the ankle ligament repair is healing well apparently, but the physio is very strict about keeping weight off it until they're satisfied with the recovery.

Speaker B: Crutches during ligament repair recovery — the non-weight-bearing protocol that crutches enforce is the medical mechanism: the ligament is reconstructed or allowed to heal without the stress of weight bearing, which would re-injure or displace the repair. Six weeks is a typical minimum for major ligament repair; the physio's strictness reflects the genuine risk of re-injury if weight bearing begins too soon.

Speaker A: He uses humour as a crutch in difficult conversations — as soon as things get emotionally real he cracks a joke and the moment passes. It works as a deflection but it means nothing ever gets actually resolved.

Speaker B: Humour as a psychological crutch — the deflection mechanism that prevents genuine engagement with difficult emotional content. The crutch analogy is precise: the humour supports function in difficult social situations but compensates for a discomfort with emotional directness that is not being addressed. Works in the short term; prevents depth and resolution in the longer term.

Speaker A: The team was using their testing framework as a crutch — they never questioned whether their tests were actually covering the right things because the framework gave them a passing score. Green lights everywhere; bugs in production.

Speaker B: Test framework as a development crutch — the false security of good-looking metrics. The crutch provides the feeling of safety while the actual need (genuine coverage of real failure modes) remains unaddressed. Green test suites and production bugs coexisting is the diagnostic sign that the testing crutch is providing support without building the actual capability of testing that matters.

Speaker A: People sometimes confuse crutch and crutches in the figurative sense.

Speaker B: In the figurative sense, crutch is used as a singular mass noun — alcohol as a crutch, not crutches. In the physical sense, you typically use crutches (plural) because one crutch provides asymmetric support and is less common. The figurative singular is idiomatic: a crutch is a single prop or compensation mechanism. The physical crutches come in pairs for stability.

Podcast 3 — Prompt engineering

Speaker B: Scenario one — a code dependency crutch audit.

Design a code dependency audit tool for a software development platform that identifies libraries and frameworks being used as crutches — imported for trivial tasks that should be implemented natively. The audit: analyses the dependency list and usage of each dependency, identifies crutch patterns including a date library imported for a single date format operation, a utility library imported for a single array operation, a UI framework imported for a single component, and a validation library imported for a single field check, calculates the ratio of dependency weight in kilobytes to the actual feature surface used, and recommends which dependencies can be replaced with native implementations, showing the native code alternative.

Speaker B: Dependency weight to feature surface ratio is the crutch efficiency metric — a 40KB library used for one function is an extreme crutch; a 40KB library used across 50 components is a genuine dependency.

Speaker A: Showing the native code alternative makes the recommendation actionable — the developer sees both the crutch identification and the replacement in one view.

Speaker B: Next — a rehabilitation tracking prompt.

Build a mobility rehabilitation tracker for a physiotherapy platform that manages the progressive removal of crutch support. Patients use crutches as a temporary support during recovery from leg and foot injuries; the goal is graduated removal of the crutch as strength and stability return. The tracker: records daily weight bearing fraction on the injured limb from zero through full weight bearing, tracks crutch type in use (both crutches full weight offset, both partial weight offset, single crutch, no crutch), logs physiotherapy exercises completed per day, measures functional milestones (can walk 10 metres without crutch, can climb one step, can walk on uneven ground), and generates a predicted crutch removal date based on current progress rate.

Speaker A: Predicted crutch removal date based on current progress rate is the patient motivation feature — seeing a specific date when they can put the crutches away is the goal that drives compliance with the rehabilitation programme.

Speaker B: Right. Now a learning dependency prompt.

Design a learning crutch identification tool for an educational platform. Learning crutches are supports that help students initially but create dependencies that prevent development of underlying skills. The tool identifies: calculator use before mental arithmetic is fluent, spell-checker use before spelling rules are internalised, formula sheet use before equations are understood, example code available during programming exercises before problem-solving approaches are developed, and search engine use during recall exercises before knowledge is consolidated. For each identified crutch, the tool shows the underlying skill that is not developing and recommends a graduated weaning protocol that progressively reduces the crutch support.

Speaker B: Graduated weaning protocol for each learning crutch is the pedagogical intervention — removing a crutch abruptly creates anxiety and failure; removing it in graduated steps allows the underlying skill to develop as the support reduces.

Speaker B: Fourth — a psychological support prompt.

Build a coping mechanism assessment tool for a wellbeing platform that distinguishes between genuine coping strategies and psychological crutches. A coping strategy builds resilience and addresses the source of stress; a psychological crutch provides temporary relief while preventing engagement with the underlying issue. The assessment asks users about their current coping behaviours and classifies each as: healthy strategy (addresses cause, builds long-term resilience), adaptive crutch (provides necessary temporary support during a crisis period), or problematic crutch (avoids the underlying issue, creating dependency). For each identified crutch, the tool suggests a pathway from crutch toward the underlying skill or resolution.

Speaker A: Adaptive crutch as a separate category from problematic crutch is the clinical nuance — a crutch is appropriate and healthy during a genuine crisis; the same behaviour becomes problematic when the crisis has resolved but the crutch remains.

Speaker B: Fifth — a prompt engineering crutch prompt.

Design an AI prompt quality assessment tool for a developer platform that identifies when developers are using prompt crutches — patterns that get results but prevent development of genuine prompting skill. Prompt crutches include: using please and thank you extensively in every prompt (politeness as a crutch that adds noise), over-explaining context the AI doesn't need, using example outputs as a substitute for clear instruction, always using the same template without assessing whether it fits the task, and requesting step-by-step thinking for every prompt regardless of task complexity. For each crutch identified, explain why it adds friction, and provide the more direct approach that achieves the same result more efficiently.

Speaker B: Over-explaining context the AI doesn't need as a prompt crutch is the anxiety-based compensation — developers who are unsure what context is necessary provide all of it, which often obscures the actual request.

Speaker B: Sixth — a full small app.

Build a single-page web app called Crutch Check — a personal dependency awareness tool. The user lists their current crutches: habits or tools they rely on that they suspect are compensating for an underlying weakness rather than building genuine capability (checking their phone when bored instead of sitting with discomfort, using a calculator for simple arithmetic, always having music on when working alone). For each crutch, they record: what underlying skill or capacity it might be compensating for, how long they have been using it, and whether they want to reduce it. A 30-day reduction challenge lets them set a specific weekly reduction goal and track compliance. All data in localStorage.

Speaker A: How long they have been using the crutch is the dependency duration field that creates self-awareness about whether this is a temporary adaptive crutch or a long-term dependency that has outlasted its original justification.

Speaker B: That's the lesson — a crutch provides support for a weakness, and the goal is always to eventually walk without it. From the axillary crutch during ankle ligament recovery to the humour deflection in difficult conversations to the test framework that provides false confidence, the crutch is the temporary support that must be progressively removed as the underlying strength develops.
