Functional fixedness
Functional fixedness is a cognitive bias that limits a person to using an object only in the way it is traditionally used. This bias restricts the scope of problem-solving and innovation by preventing individuals from recognizing alternative uses for an object or concept.
How it works
Functional fixedness occurs when an individual's cognitive process is constrained by the conventional functions and uses of objects, making it difficult for them to conceive new solutions or innovative applications. This bias often arises because people cling to their existing beliefs and assumptions, which leads to an over-generalization of known information.
Examples
- A classic example of functional fixedness is the 'candle problem,' where individuals must figure out how to attach a candle to a wall using a candle, a box of thumbtacks, and matches. Many struggle because they do not see that the box can be used as a candle holder rather than just a container for the tacks.
- In everyday life, functional fixedness can be seen when someone only sees a paperclip as a tool for holding papers together, rather than using it as a lock pick, a device to reset electronic equipment, or a makeshift zipper pull.
Consequences
Functional fixedness can lead to a lack of creativity and innovative thinking, potentially causing people to miss out on simple solutions to problems. It can also result in inefficiencies in business, technology development, and everyday problem-solving tasks.
Counteracting
To counteract functional fixedness, individuals can practice 'thinking outside the box,' engage in brainstorming sessions, and be exposed to diverse perspectives and problem-solving approaches. Other techniques include questioning assumptions, exploring alternative uses for common items, and engaging in creativity-stimulating exercises.
Critiques
Some critics argue that functional fixedness is not always a negative bias, as certain situations may benefit from adhering to conventional uses of objects to achieve efficiency and reliability. Furthermore, the bias may be less of a limitation in environments where innovation is not prioritized.

Context
SwiftCart is a mid-size e-commerce retailer that invested in automation to keep up with seasonal demand. The operations team purchased a robotic arm explicitly marketed and configured for palletizing incoming boxes at the receiving dock.
Situation
The robotic arm lived its life stacking and wrapping pallets on one shift while human pickers handled order fulfillment on another. During peak season the company repeatedly hired temporary pickers to meet surge demand instead of investigating whether the new robot could help with order picking.
The Bias in Action
Operations and engineering treated the robot as a single-purpose palletizer because that was how the vendor demonstrated it and how it was installed. Team meetings reinforced that 'this robot is for pallets,' so alternative uses were dismissed without prototyping. Even when a floor supervisor suggested testing the arm for picking and placing items into outbound cartons, managers rejected the idea as 'risky' and outside the device's purpose.
Outcome
SwiftCart continued to rely on manual pickers through the holiday quarter, incurring high temporary labor costs and longer fulfillment times. A competitor who repurposed similar equipment reduced picking labor and shortened lead times, gaining higher same-day shipment rates and better customer ratings.
