Describing Functional Fixedness
It is the tendency to see objects as only working in a particular way. You might view a thumbtack as something that can only be used to hold paper to a corkboard.
Functional fixedness can prevent people from seeing other uses for an object. It can also diminish our ability to think of creative solutions to problems.
"I think the next best thing to solving a problem is finding some humor in it." -Frank Howard Clark
