The Foundation of Professional Liability#
Before we can understand AI standard of care, we must understand what “standard of care” means in traditional professional liability.
The Basic Framework#
In negligence law, professionals owe a duty to exercise the care that a reasonably competent member of their profession would exercise under similar circumstances. This is the “standard of care.”
When a professional fails to meet this standard and that failure causes harm, they may be liable for negligence or malpractice.
How Standards Are Established#
Courts determine the applicable standard of care through:
- Expert testimony - Other professionals testify about what a competent practitioner would do
- Professional guidelines - Standards published by professional organizations
- Regulatory requirements - Government mandates that establish minimum expectations
- Industry custom - Common practices in the field
The AI Complication#
AI disrupts this framework in several ways:
The Novelty Problem#
When a practice is new, there may be no established custom or guidelines. Courts must reason by analogy or from first principles.
The Expertise Gap#
Who is qualified to testify about what “reasonable” AI governance looks like? Computer scientists? Domain experts? AI ethicists? Courts are grappling with this question.
The Black Box Problem#
Traditional standard of care analysis assumes the professional understands their tools. But AI systems may be opaque even to their operators.
The Speed of Change#
Standards of care typically evolve slowly. AI capabilities change rapidly. What was reasonable last year may be negligent today.
The Key Questions#
For any AI system in professional practice, we must ask:
- What duty did the professional owe?
- What would a reasonably competent professional have done regarding AI use?
- Did the professional’s AI-related conduct fall below that standard?
- Did that failure cause the harm complained of?
These questions are being litigated across every field where AI is deployed. The answers will shape practice for decades to come.
