Philosophy, Law & Politics
Section 1
Core Idea
Duty of care is the legal and moral obligation to act with reasonable concern for the safety and well-being of others who could be affected by your actions or decisions. In law, it establishes that certain relationships — doctor-patient, director-shareholder, employer-employee — create enforceable responsibilities. Breaching that duty through action or inaction constitutes negligence. But the concept extends far beyond courtrooms. Any founder, manager, or leader who controls resources or makes decisions that affect others carries an implicit duty of care — to customers, employees, investors, and communities. The model matters because duty of care sets the floor for acceptable behavior: not heroism, not perfection, but the minimum standard of a reasonable person exercising ordinary prudence.

How to See It
Product Safety
You're seeing it when a company ships a product knowing about a defect that could harm users, calculating that recall costs exceed expected lawsuit payouts — a textbook breach of duty of care rationalized by financial logic.
Management
You're seeing it when a manager ignores reports of burnout or harassment on their team because addressing it would require difficult conversations — failing the duty of care that comes with authority over others' working conditions.
Fiduciary Governance
You're seeing it when a board of directors rubber-stamps management proposals without independent review, violating their fiduciary duty of care to shareholders by failing to exercise informed judgment.
Section 3
How to Use It
Before making any decision that affects others, ask whether a reasonable person in your position would consider the potential harm and take steps to prevent it. Duty of care doesn't require perfection — it requires that you thought about the consequences, gathered relevant information, and acted prudently. Build systems that make duty of care structural rather than personal: checklists, review processes, escalation paths, and clear ownership of safety-critical decisions.
Decision filter
"Would a reasonable person in my position consider this decision careful enough — or would they say I should have known better and done more?"
As a founder
Duty of care is the minimum standard you owe every stakeholder. Build it into your operating system — product review processes, safety checks, manager training — so that care doesn't depend on individual heroism. The founder who treats duty of care as infrastructure rather than intention builds a more durable company.
Section 5
Founders & Leaders
Isadore SharpFounder of Four Seasons Hotels and Resorts
Sharp built Four Seasons on the principle that duty of care to employees was the foundation of duty of care to guests. His Golden Rule philosophy — treat employees as you want them to treat customers — operationalized care as a business system rather than a slogan. Sharp understood that care couldn't be mandated through scripts; it had to emerge from an organizational culture where employees themselves felt cared for. Every operational detail, from training to empowerment policies, was designed to lower the barriers to exercising care. For founders, Sharp demonstrates that duty of care scaled through culture compounds into brand equity, loyalty, and a moat that competitors can't easily replicate.

Pairs-with
Negligence
Negligence is what happens when duty of care is breached. Duty of care defines the standard; negligence is the failure to meet it. Understanding one requires understanding the other — they are two sides of the same legal and moral framework.
Warns-against
Moral Hazard
Moral hazard arises when someone is insulated from the consequences of their actions. Duty of care counteracts moral hazard by making individuals legally and morally accountable for the foreseeable harms of their decisions.

Skin in the Game
Skin in the game means bearing the consequences of your decisions. Duty of care formalizes this — it says that those who make decisions affecting others must exercise reasonable prudence, creating accountability even when market forces don't.
Section 8
One Key Quote
— Lord Atkin (Donoghue v Stevenson, 1932)"You must take reasonable care to avoid acts or omissions which you can reasonably foresee would be likely to injure your neighbour."
Section 11
