Cahn's theorem

Cahn's theorem, stemming from economics and decision theory, states that when faced with choices, the preference for an option can change based on how it's framed or presented, even if the options themselves remain unchanged. Essentially, the way information is communicated can influence our decisions. For example, describing a product as "90% effective" might be more appealing than saying it has a "10% failure rate," despite both statements being mathematically equivalent. This highlights the importance of context in decision-making and how people's choices can be swayed by perceptions rather than just facts.
