**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**
