What is dunkers candle problem?

The Dunker's candle problem is a cognitive puzzle used to study problem-solving skills and functional fixedness. It was first introduced by psychologist Karl Dunker in 1945. The problem involves a subject being given a box of thumbtacks, a candle and a book of matches. Their task is to attach the candle to the wall in such a way that it can be lit and the candle wax won't drip on the floor.

The problem requires individuals to overcome functional fixedness, which is the tendency to see objects only in their conventional and familiar uses. In this case, most people are initially fixated on the idea of using the thumbtacks to attach the candle to the wall and fail to consider other solutions.

The solution to this problem involves using the box of thumbtacks as a platform to hold the candle and then attaching the box to the wall with the thumbtacks. This solution requires individuals to think outside the box, use creative thinking, and consider unconventional uses for objects.

The Dunker's candle problem is often used in cognitive psychology research to study problem-solving strategies, creativity, and the cognitive processes involved in overcoming functional fixedness.
