Why Google doesn't give yes or no answers
When you type a yes or no question into Google — "should I quit my job yes or no", "does he love me yes or no", "am I pregnant yes or no" — Google shows you links to articles and tools. It does not make the decision for you, because Google is a search engine: it finds information, it does not interpret it for your specific situation or make random choices.
What most people searching "Google yes or no" actually want is one of two things: a random yes or no (when they genuinely cannot decide and want chance to pick), or a reasoned yes or no (when they want an outside perspective on their specific situation). These are very different needs — and different tools serve each one.
