Functional fixedness

Functional fixedness is a bias where we can only think of a narrow set of functions for a tool. A knife is made to cut things. A cotton swab is for cleaning your ears.

It is common to stick to what we know. We become comfortable repeating tasks in a way that fits with our preconceived ideas on how they should be done, especially if these ideas worked in the past. But being stuck in our methods can stop us from discovering better solutions.

Functional fixedness experiment

Functional fixedness experiment

Karl Duncker first described functional fixedness in 1945. 

In a study, participants were given a candle, a box of tacks and a book of matches. Participants were challenged to attach the candle to a wall so that it would not drip on the floor. Instead of noticing that the tack box could be used on its own, they only saw it as a storage box.

Make a conscious effort

Studies suggest that it's possible to teach your brain to move away from functional fixedness and embrace creative thinking.

When faced with a task or problem at work, try stepping away from how it's always been done. Instead, explore the problem creatively to find alternative solutions.

Abstract the problem

A step away from functional fixedness is to break a problem into its basic components. Instead of focusing on the details, only focus on the essential elements. When the problem is stripped from unnecessary detail, you're less likely to fall back on functional fixedness.

For example, if you need to re-pot a plant, instead of finding a plant pot, look for an object to hold the plant, such as a mug or jar.

Remove judgment

When you approach a task in a new way, it's easy to judge unusual ideas harshly and reject them.

Be open to new perspectives instead of limiting your options. At first, you should not consider any idea as too strange.

Look for inspiration

A different industry in another sector could have a simple solution to your issue that you have not thought of due to function fixedness.

Explore adjacent industries for creative solutions. For example, ask a friend how they would approach your issue in their industry.

Expand your network

Crowdsourcing is an excellent way to get the support of external participants to find solutions.

For example, LEGO encourages fans to submit their own ideas instead of only relying on in-house designers. The most popular will be reviewed, and if approved, will be manufactured.

Great interesting short snippets of informative articles. Highly recommended to anyone who loves information and lacks patience.

Ashley Anthony

This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!


Don’t look further if you love learning new things. A refreshing concept that provides quick ideas for busy thought leaders.

Shankul Varada

Best app ever! You heard it right. This app has helped me get back on my quest to get things done while equipping myself with knowledge everyday.

Laetitia Berton

I have only been using it for a few days now, but I have found answers to questions I had never consciously formulated, or to problems I face everyday at work or at home. I wish I had found this earlier, highly recommended!

Jamyson Haug

Great for quick bits of information and interesting ideas around whatever topics you are interested in. Visually, it looks great as well.

Giovanna Scalzone

Brilliant. It feels fresh and encouraging. So many interesting pieces of information that are just enough to absorb and apply. So happy I found this.
