Should friends split a restaurant bill evenly?
For: equal splitting keeps a shared meal simple and avoids turning every order into an accounting exercise.
Against: equal is not fair when one person ordered much more, cannot afford the same meal, or did not agree to subsidize it.
Switch test: does the group need a shared rule before ordering, or is a receipt enough afterward?
Is tipping a fair system for paying service workers?
For: customers can reward care directly and workers may benefit from a visible connection between service and pay.
Against: essential income should not depend on customer mood, and the system hides the employer’s wage responsibility.
Switch test: would you keep tipping if menu prices rose and base pay became transparent?
Should family members be expected to lend money?
For: close relationships create a duty to help when someone faces a genuine emergency.
Against: a loan can become coercion, resentment, or a permanent financial role nobody freely chose.
Switch test: should the obligation depend on the emergency, the borrower’s plan, or the lender’s ability to say no?
Should delivery fees be paid by the customer or the platform?
For: a visible fee lets customers understand the cost of convenience and helps platforms price the service honestly.
Against: surprise fees distort the choice, while workers can be squeezed when the platform passes every cost through.
Switch test: is transparency enough if the worker still receives an unpredictable share?
Should couples combine all of their money?
For: a shared household needs shared planning, and one pool can reduce secrecy and unequal exposure to bills.
Against: financial autonomy is part of consent, especially when income, debt, or spending habits differ.
Switch test: would a joint essentials account plus private money preserve the trust you want?
Should employees know what their coworkers earn?
For: transparent ranges can reveal unequal pay and give people evidence for a fair negotiation.
Against: full disclosure can expose private circumstances and turn a colleague’s compensation into a workplace spectacle.
Switch test: is role-level transparency enough, or does fairness require individual numbers?
Is buying a home always better than renting?
For: ownership can provide control, stability, and a path to build equity over time.
Against: renting buys flexibility and avoids concentrating savings in one asset with maintenance and location risk.
Switch test: how should the answer change with the time horizon, local price, and opportunity cost?
Should people prioritize saving over enjoying money now?
For: a buffer buys resilience and protects future choices when income or health changes.
Against: an abstract future can become an excuse to postpone every meaningful experience.
Switch test: what minimum safety margin lets you spend without turning prudence into fear?
