🧠 Riddle of the Day
Riddle of the Day
I can be kept without being held. I can be broken without being dropped. I can be made in a second and forgotten in a day.
What am I?
Answer: A promise
A promise is not a physical object, so “kept” and “broken” have to mean something else. People keep a promise by following through and break it by not doing so. It takes a moment to say and, sadly, can vanish from memory just as fast.
💡 Interesting to Know
Where “Lateral Thinking” Came From
The phrase was coined by the Maltese psychologist Edward de Bono in 1967. He used it for solving problems by stepping sideways and looking at them from a new angle instead of pushing straight ahead.
The Moses Illusion
Ask people, “How many animals of each kind did Moses take on the ark?” and many answer “two” without noticing the mistake. It was Noah, not Moses. Psychologists use this kind of question to show how easily we skim past errors.
When Old Habits Block New Answers
In the 1940s, the psychologist Abraham Luchins gave people a series of water jar puzzles. Once people learned one method, many kept using it even when a simpler one was available. This is called a mental set.
The Candle Problem
In 1945 the psychologist Karl Duncker asked people to attach a candle to a wall using a box of tacks and matches. Many struggled because they saw the box only as a container, not as a shelf. This is known as functional fixedness.
Riddles Are Very Old
The riddle of the Sphinx is one of the oldest famous riddles in Greek myth. Old English poets also loved them. The Exeter Book, a manuscript more than a thousand years old, contains nearly a hundred riddles.
A Riddle Contest in a Famous Novel
In J.R.R. Tolkien’s The Hobbit, published in 1937, Bilbo Baggins survives a dangerous night by winning a riddle contest against Gollum.
The “Aha!” Moment Is Real
Brain researchers have observed a brief burst of activity just before people report a sudden insight. That little jolt of satisfaction when a riddle finally clicks is more than a feeling.
