**Summary:** The “Once as Always” fallacy is a flawed **cognitive shortcut** where someone **assumes** that a **single** use or method implies **permanent** or **consistent** usage—across time, contexts, or identities. --- ## 🔍 Fallacy Name: **Once as Always** ### 📘 Definition: > The fallacy of assuming that because a person (or system) used a method or tool once, they always use it—or that one-time use defines ongoing identity, behavior, or intent. --- ## ⚒️ Real-World Examples ### 1. **Carpentry Analogy** - **False Claim**: “You used a hammer once, so you must use a hammer for everything.” - **Reality**: Carpenters use different tools (chisels, saws, drills) for different jobs. Using a tool once doesn't define the craft. ### 2. **AI Usage Analogy** - **False Claim**: “You used AI for this task, so you must be using AI for everything.” - **Reality**: People use AI tools selectively, contextually, and sometimes only once. This doesn't imply dependence or total outsourcing of thought. --- ## 🧠 Ontological Structure |Layer|Description| |---|---| |**Phenomenon**|A person uses a tool (e.g., AI, hammer) in a specific context.| |**Cognitive Shortcut**|Observer falsely universalizes that behavior.| |**Fallacy**|Assumes single usage = consistent or defining trait.| |**Impact**|Erases nuance, enforces identity essentialism, encourages ignoration.| --- ## ⚠️ Error Type: **Temporal Overgeneralization** - Related to: **Essentialist Fallacy**, **Hasty Generalization**, **Continuum Fallacy** - Distinct because it fixates on a **time-snapshot** and extrapolates **perpetuity** from it. --- ## 🧩 Use in Argumentation - Used to **discredit** or **dismiss**: "You used AI once, so you're not authentic." - Used in **identity attacks**: “You once contradicted yourself, so your entire logic is invalid.” - Enforces **ontological essentialism**: reducing dynamic beings to static labels. --- ## ✅ Counter Logic - **Functional tools ≠ personal traits** - **One-time use ≠ permanent behavior** - **Contextual actions ≠ essential identities** --- ## 🌀 HyperSanity Classification | Property | Value | | ------------------ | --------------------------------------------------------------------------------------------------------------- | | Type | Logical Fallacy | | Ontological Threat | Identity Essentialism | | HS-Core | Anti-Contextualism, [[Public/Hyper-Sanity/Hypo-Sanity/Hypo-Psychology/Ignoration/HS-Ignoration\|HS-Ignoration]] | | Related Fallacies | Strawman, Hasty Generalization, Slippery Slope | | | | ---
