Lorem ipsum dolor sit amet, consectetur adipiscing elit. Cur ipse Pythagoras et Aegyptum lustravit et Persarum magos adiit? Quo plebiscito decreta a senatu est consuli quaestio Cn. Neque enim disputari sine reprehensione nec cum iracundia aut pertinacia recte disputari potest. Quid est, quod ab ea absolvi et perfici debeat? Multa sunt dicta ab antiquis de contemnendis ac despiciendis rebus humanis; Ab hoc autem quaedam non melius quam veteres, quaedam omnino relicta. Duo Reges: constructio interrete.

Non enim iam stirpis bonum quaeret, sed animalis. Immo alio genere;

Si de re disceptari oportet, nulla mihi tecum, Cato, potest esse dissensio. Venit enim mihi Platonis in mentem, quem accepimus primum hic disputare solitum; Quonam modo? Ut enim consuetudo loquitur, id solum dicitur honestum, quod est populari fama gloriosum. Pisone in eo gymnasio, quod Ptolomaeum vocatur, unaque nobiscum Q. Quid, quod homines infima fortuna, nulla spe rerum gerendarum, opifices denique delectantur historia? Hanc quoque iucunditatem, si vis, transfer in animum;

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sin eam, quam Hieronymus, ne fecisset idem, ut voluptatem illam Aristippi in prima commendatione poneret. Dempta enim aeternitate nihilo beatior Iuppiter quam Epicurus; Cur igitur, inquam, res tam dissimiles eodem nomine appellas? Te enim iudicem aequum puto, modo quae dicat ille bene noris. Ergo instituto veterum, quo etiam Stoici utuntur, hinc capiamus exordium. Istam voluptatem perpetuam quis potest praestare sapienti? Nunc ita separantur, ut disiuncta sint, quo nihil potest esse perversius. Aliter enim nosmet ipsos nosse non possumus. Voluptatem cum summum bonum diceret, primum in eo ipso parum vidit, deinde hoc quoque alienum;

Duo Reges: constructio interrete. His similes sunt omnes, qui virtuti student levantur vitiis, levantur erroribus, nisi forte censes Ti. Sin te auctoritas commovebat, nobisne omnibus et Platoni ipsi nescio quem illum anteponebas? Omnis enim est natura diligens sui. Scio enim esse quosdam, qui quavis lingua philosophari possint;

Paulum, cum regem Persem captum adduceret, eodem flumine invectio? Hanc ergo intuens debet institutum illud quasi signum absolvere. Nam ante Aristippus, et ille melius. Tanti autem aderant vesicae et torminum morbi, ut nihil ad eorum magnitudinem posset accedere. Aut unde est hoc contritum vetustate proverbium: quicum in tenebris? Nec tamen ullo modo summum pecudis bonum et hominis idem mihi videri potest. Solum praeterea formosum, solum liberum, solum civem, stultost;

Limitations

There are few substantial critiques of Functional Fixedness and it is a reasonably accepted heuristic. There have been some debates on nuances — for example, one study claiming that monetary incentives made Functional Fixedness worse, with another unable to repeat that result. But I was unable to find any studies that deny its existence or impact. 

Indeed, variations on the Candle Problem persist — with a written version delivered at Stanford University resulting in similar results.

Functional Fixedness was even put to the test with non-industrialised societies to determine the impact of cultural factors — with a recent study conducted within the Amazon region of Ecuador to compare with industrial culture. The results seemed to demonstrate that Functional Fixedness is culture blind and not related to the level of industrialisation or technology of a society. 

In Practice

Adapting during coronavirus. 

Much of our world changed during 2020. Many people were left with redundant buildings or businesses that relied on pre-Covid conditions and practices. 

Meanwhile, some companies broke through Functional Fixedness to reinvent themselves. A wonderful example of this was the Rubbens gin distillery in Belgium which moved quickly, redirecting its production of alcohol to produce disinfectant by March 2020. Other distilleries around the world soon followed suit. 

Breaking Functional Fixedness in tech startups. 

About a decade ago Canadian billionaire Daniel Butterfield, was trying to launch an online game called Glitch. Ever heard of it? Me neither. 

At the time the team created an internal messaging system to coordinate their work on the game. It was a little while in before they realised that the messaging system had more value than the game itself — and so Slack was launched. 

The Candle Problem.

This model is still best described through Duncker’s original Candle Problem from 1945. In the experiment, participants were given the following objects: 

  • A box of thumbnails

  • Matches

  • A candle

They were then asked to attach the candle to the wall while ensuring that wax would not drip on the table below once lit. The clock is ticking, how would you solve this problem? Pause for a moment and consider what you would do.

You might try pinning the candle directly to the wall or melting the candle to stick it to the wall. Both would leave the table covered in wax as the candle burnt down. A small proportion of people discovered the real solution. 

Meanwhile, another group of participants were given the same task, but were given the following objects: 

  • A box

  • Thumbnails

  • Matches

  • A candle

For those playing at home, you’ll notice that the object list is identical to the first one — only this time the thumbnails were not placed in the box.

This subtle change made the ‘box’ an object in itself and a potential part of the solution rather than just a container for thumbnails. It broke the Functional Fixedness related to, dare I say it, ‘in the box thinking.’

This slight tweak resulted in almost all participants solving the problem — simply pinning the box to the wall and placing the candle inside it. 

Angels on a pin. 

Angels on a Pin is a 1959 essay by American academic test designer Alexander Calandra describing a case where a colleague was about to give a student zero to a Physics question. The question was ‘Show how it is possible to determine the height of a building with the aid of a barometer.'

The student's answer was to tie the barometer to a rope, lower the rope and measure the resulting distance. Technically correct, but not the physics assessment they were looking for. 

The academics decided to give the student another chance, asking them to demonstrate knowledge of physics in their next attempt. The student’s second answer was to drop the barometer from the top of the roof and time how long it took to hit the ground, then use the formula S = 0.5at squared to calculate the height. 

The student was able to offer several other options including measuring the barometer versus building shadows, creating a pendulum with the barometer and comparing gravity at the different heights, or offer the barometer to the superintendent if he revealed the height of the building. 

All of the answers continued to expose the Functional Fixedness of the academics who crafted the original question.

Origins & Resources

The term Functional Fixedness was coined by Karl Duncker in 1945, who described it as a “mental block against using an object in a new way that is required to solve a problem.” His original study involved the Candle Problem, outlined in the overview above. 

This Candle Problem, in many ways, has become a de facto test of creative insights, leading to the 2009 study by William Maddux and Adam Galinsky to assess the impact of travelling and living overseas on creativity — they concluded that a period spent adjusting to living (not just travelling) abroad did increase creativity.
