In psychology, the concept of 'functional fixedness' refers to the tendency to perceive objects only in terms of their most common or typical use, thereby limiting the ability to think of alternative functions. This cognitive bias can hinder problem-solving because individuals fail to see novel ways to use familiar items. Overcoming functional fixedness often requires a deliberate shift in perspective, allowing one to consider unconventional applications for objects in order to reach a solution.

Professor: Let me illustrate this with a classic experiment. Participants were given a box of tacks, a candle, and a book of matches, and asked to attach the candle to a wall so it could burn properly. Most people tried to use the tacks to pin the candle directly to the wall, but that didn't work because the candle was too thick. Others tried to melt the wax and stick it, but it wouldn't hold. The solution was to empty the box, tack the empty box to the wall, and place the candle inside it. The key was to see the box not just as a container for tacks, but as a potential shelf. Those who overcame functional fixedness succeeded, while those who saw the box only as a tack container failed.
