Competence

Competence is the ability to perform successfully, not knowledge.

The phrase "knowledge-how" is linguistic convention, not epistemic analysis. What we call "knowledge-how" is better understood as competence. Competence does not require or constitute knowledge.

Properties

Competence:

• is the ability to produce successful outcomes
• is about that something works, not why
• is improved through practice, feedback, and repetition

Competence does NOT:

• require explanatory understanding
• support counterfactual reasoning
• constitute knowledge

Counterfactuals

Explanation must support counterfactual claims: If this were different, the outcome would be different.

Competence does not require this. A skilled performer may not know:

• Why the performance succeeds
• Under what conditions it would fail
• How to modify it for novel situations

Competence is demonstrated by outcomes. Knowledge is demonstrated by explanation.

Independence

Competence and knowledge are independent. You can have either without the other.

Competence without knowledge:

• A pianist plays a complex piece but cannot articulate the motor sequences involved.
• A chess master "sees" good moves but cannot fully explain the evaluation.
• A dog fetches on command without understanding the concept of fetching.
• A neural network classifies images accurately without any model of what it's classifying.

Knowledge without competence:

• Understanding how to perform surgery does not make you a surgeon.
• Knowing the physics of a bicycle does not mean you can ride one.
• Explaining the rules of chess does not make you a good player.

Implications

The conflation of competence and knowledge has consequences:

1. Inflated knowledge claims. If successful performance is knowledge, then thermostats "know" when to turn on and calculators "know" arithmetic.

2. Obscured distinction. Knowledge enables counterfactual reasoning and error correction. Competence may succeed without either.

3. Mischaracterized AI. A system that predicts well or performs reliably may have competence without any explanatory understanding.
