Creativity is one of the most prized skills of the 21st century yet there is no scientific consensus on how it should be measured
Despite the broad consensus on the importance of creative thinking skills, they are still rare to find on the job market. The results of the Future Jobs Survey 2018, by the World Economic Forum suggest that while creativity is on demand now, the need will only grow in the near future. They found that creativity, originality and initiative skills were ranked number 5. By 2022, they predict it will be number 3. In contrast to demand, creativity is one of the hardest skills to identify in job candidates. According to PWC’s 20th CEO Survey Global Talent study from 2017, creativity is on today’s ‘Skill Battlegrounds’ as it is a very important skill but difficult to find.

Given the demand, we should focus on fostering and enhancing these skills. For that to happen it is necessary to have a tool to assess creativity. However, given the complex nature of the concept, and despite the tremendous effort scientists have put into research, there is still no established method for creativity assessment. This proves to be a bottleneck in the process of fostering creativity.
Based on literature, assessment in the form of a battery of tests could be a viable solution.
“We argue that variety in DT [divergent thinking] assessment approaches should be used to reveal further benchmark findings, which are very useful when it comes to comparisons of competitive theories or the examination of new research topics related to DT.” (1)
“In order to effectively measure the target constructs, creativity research should ultimately seek to utilize a battery of tasks in order to capture shared variance. Intelligence researchers have benefited enormously from this approach, which has allowed them to reliably predict elusive constructs with great success.” (2)
Based on the suggested solution of using a battery of tests, and the fact that most existing studies testing divergent thinking have few participants, we are creating an online platform for studying creativity that is open for anyone to use. We expect similar participation numbers as in our Skill Lab: Science Detective game that has reached more than 20.000 players. This is significantly more participants than an initial ad hoc review of existing literature found for divergent thinking studies, which had an average number of participants around 220.
CREA is a combination of innovative games and validated tests. It is a suite of three open-ended games intended to measure creativity (novelty and value), Convergent Thinking (CT) and Divergent Thinking (DT) using rater-based and empirical methods, including algorithmic assessment. The suite also includes a battery of widely accepted DT and CT ability tests as well as variations of psychometric ability tests for general cognitive ability, including an abstract reasoning test.
1: Can a portfolio-based approach (battery of games/tests) reveal deeper insights into the constructs underlying creativity?
2: To what extent can scalable, digital measures of creativity supplement or replace traditional expert-assessed tests?
3: To what extent are aspects of creativity, such as divergent and convergent thinking, domain general or contextual?
4: To what extent does task-based creativity assessment reflect real-world applications of creativity?
5: What can we learn about the relationship between creativity and general cognitive abilities?
We, the people at ScienceAtHome, place great emphasis on doing research in a way that is not daunting to the population. We work to translate complex problems into games that the public can engage with, and thus contribute to solving problems in various fields of science without having a PhD degree, and while having fun.
Game-based assessment tools are gaining more and more attention in the field of psychology. They are fun and show similar validity as psychometric tests. By using games, some effects (such as test anxiety or the researcher effect) can be removed from the equation thus serving us cleaner data regarding the tested phenomenon. They also allow us to make observations that are closer to the real world phenomenon and are motivating and engaging. Plus, many people are playing digital games as part of their daily lives, so we can gather assessment information without stopping their daily activities (4).
The three mini games we use in the CREA suite are: crea.tiles, crea.shapes, and crea.blender.
crea.tiles consists of 10 tiles that can be moved around by the player, one at a time. The player must place a tile in an empty spot adjacent to the edge of another tile. They can only move tiles at the edges of the shape which would not result in any other tile ‘by itself’ without another adjacent tile. The shape is always one continuous shape.
crea.tiles. ‘O’ tiles can move to any ‘Z’ location. ‘X’ tiles cannot move.
Players can interact with the game in various different modes. They have to create as many digits, dogs or creatures as they can, in the respective modes. They will also be asked to label their creations. In the “Challenge” mode, the players get a Target figure. They will see four figures and their objective is to work out which figure is closest in appearance to the Target figure. Once they make their choice, they try to re-create the Target figure, starting with their chosen figure. In the “Open play” mode the players can play around as they wish, and save the figures they find interesting. In the end, they can select their best figures, which they submit to the voting pool. The voting pool consists of figures that players deemed their most interesting creations. At the end of the Open play, all players can see other players’ creations and vote which ones they find more interesting.
In crea.shapes, players are presented with two overlapping rectangles. They may resize and move both rectangles however they like. Where the two rectangles overlap, a darker shape appears. This shape is the focal shape. The players may take a snapshot of any given shape which they have created. The objective is to create as many different shapes as they can.
crea.shapes. Players create new shapes where the two rectangles overlap.
crea.shapes has been created based on the Open Creativity game, which was designed to study how creative outcomes can ensue over time (8).
crea.blender combines strengths of humans and algorithms to create unique images. In the game, players can play around with blending multiple images together in order to get new, interesting compositions. How “much” each image should contribute to the resulting picture is up to the player: each image’s weight can be adjusted using a slider underneath.
There are three modes in the game and the player has different objectives in each. In the “Create animals” mode, the task is to create as many animal-like figures as possible. In the “Challenge” mode the player gets a Target image. They will see 3 sets of images and their objective is to work out which set was used to create the Target image. Once they make their choice, they try to re-create the target image with their chosen set. In the “Open play” mode the player can play around as they wish – and save the images they find most interesting. In the end, they can select three of their best pictures and submit them to the voting pool. The voting pool consists of images that players deemed as their most interesting creations. At the end of the Open play, all players can see other players’ creations and vote which ones they find most interesting.
crea.blender is based on the project Artbreeder (9), which aims to be a new type of creative tool that empowers users’ creativity by making it easier to collaborate and explore. The main technology behind both crea.blender and ArtBreeder are Generative Adversarial Networks. Try out the original ArtBreeder here.
Computational creativity: A use case of hybrid intelligence
crea.blender is part of the field called Interactive Evolutionary Computation (IEC), artificial evolution guided by human direction. IEC is a collaborative process between humans and algorithms. Collaborative Interactive Evolution, which is involvement of many users in the IEC process, drives crea.blender’s system.
Algorithms are becoming increasingly prevalent in our day to day lives and there are many fields such as Human Computer Interaction (HCI), Human Computation and Hybrid Intelligence that explore the relationships between humans and algorithms.
CREA is a project of the Center for Hybrid Intelligence which focuses on using open crowd science to map the boundary between human and artificial intelligence.
Divergent and convergent thinking
Researchers mostly agree on two things: that creativity is a mixture of something being new and being useful at the same time, and that creativity involves two distinct cognitive processes: being able to come up with many diverse ideas (divergent thinking – DT), and being able to select and pursue an idea that is good and useful (convergent thinking – CT).
Currently, creativity is assessed mainly through divergent thinking test batteries such as the Torrance Test of Creative Thinking (10, 11) and Guilford’s Structure of Intellect DT tests (13). The Remote Association Test is the only widely used test for convergent thinking. Our CREA suite includes the following three tests on divergent and convergent thinking.
Measuring divergent thinking
Fluency is operationalized by the number of responses to a given stimulus.
Originality is operationalized as the uniqueness of a response to a stimulus.
Flexibility is operationalized as the uniqueness of categories of response to a stimulus.
Elaboration is operationalized through the level of detail and development of the idea.
Alternative Use Test
Testing Divergent Thinking
Participants are asked to list as many unusual/alternative uses for different objects as they can.
Prompt: List as many unusual/alternative uses for a tire as you can.
Sample responses: Hula hoop, hat, bouncy shoes, toy, swing
DT skills are assessed through measuring flexibility, fluency, originality, and elaboration.
Figural test from Torrance Test of Creative Thinking
Testing Divergent Thinking
Participants are asked to make additions to the shapes to create something meaningful.
Prompt: Draw something in each circle that incorporates the circle into the drawing as a whole
DT skills are assessed through measuring flexibility, fluency and originality.
Remote Association Test: linguistic and visual
Testing Convergent Thinking
Participants are asked to come up with the solution that connects all three elements they are given.
Prompt: what word can form compound words with the three stimuli words?
Sample responses: 1. cheese, 2. ice
Prompt: what co-occurs with the three stimuli images?
Sample response: water
CT skills are measured based on the number of steps and time it takes to reach a given solution.
General cognitive abilities is an umbrella term for distinct processes in the brain. Cognitive abilities are for example processing speed, memory, recall, and many more mental processes that are needed to carry out any task at hand. Creativity and general cognitive abilities seem to be relying on the same executive functions (updating, openness), though the nature of their relationship remains unclear (14). Our CREA suite includes the following three tests for assessing general cognitive abilities.
Abstract reasoning test
A participant is presented with a matrix of 3×3 geometric designs, with one piece missing. The participant’s task is to identify the piece, from a set of pieces, that completes the pattern in the matrix that must also be worked out. The questions and answers are all non-verbal. The test is designed to measure non-verbal, abstract reasoning. (15)
Prompt: In this task, you will be shown a 3×3 grid of patterns. The last one, in the bottom right-hand corner, is missing. You need to select which of the four possible patterns along the bottom fits into the gap.
The basic idea of Navon’s study is that when objects are arranged in groups, there are global features and local features. For example, a group of trees has local features (the individual trees) and the feature of a forest (the trees together).
The basic finding of Navon’s work is that people are faster in identifying features at the global than at the local level. This effect is also known as global precedence.
This task is designed to measure local and global processing speed.
Prompt: Decide if a letter is or contains the letter H or S.
The participant needs to press buttons corresponding to their choices.
Wisconsin Card Sorting
Participants must classify cards according to different criteria. There are four different ways to classify each card, and the only feedback is whether the classification is correct or not. One can classify cards according to the color of its symbols, the shape of the symbols, or the number of the shapes on each card. The classification rule changes every 10 cards. This implies that once the participant has worked out the rule, the participant will start making one or more mistakes when the rule changes. The task measures how well people adapt to the changing rules.
This is a test of cognitive reasoning.
Creativity is one of the essential skills for the 21st century, and schools everywhere are attempting to assess and foster creativity in their students. For example in the US, for Pre-K (age 3-5) the Figural version of Torrance Test of Creative Thinking (TTCT), Thinking Creatively in Action and Movement, Unusual Box, Alternative Use Test, and the Test for Creative Thinking – Drawing Production are typically used. For K-12 the full TTCT and the Evaluation of Potential Creativity are also used.
We also believe that creativity is an important aspect of education, hence our motivation to contribute to and make an impact on the research in the field. To illustrate the role of creativity in the big picture, we can use the Sustainable Development Goals framework developed by The Organisation for Economic Co-operation and Development (OECD). The purpose of this framework is to deliver universal goals and targets in social, economic and environmental contexts across all countries, in order to tangibly improve the lives of citizens.
According to research, the lack of understanding of complex, contextual and nuanced skills like creativity, empathy, cooperation, and other skills, all commonly referred to as 21st century skills or soft skills, has been identified as a fundamental roadblock in reaching some of the Sustainable Development Goals like ‘Quality Education’ and ‘Decent Work and Economic Growth’ (16).
With CREA, we are moving toward creating a framework allowing a citizen-based assessment and measurement of creativity. This will involve creating a collaboration between members of the public and scientists, ultimately allowing the public to co-create the project with us. We have successfully utilized this methodology in our cognitive profiling game, Skill Lab: Science Detective. More than 20.000 people have participated since Skill Lab: Science Detective launched in collaboration with Danish Broadcasting (DR) in September 2018.

Associate Professor Carsten Bergenholtz is a social scientist studying individual and collective problem-solving at the Department of Management at Aarhus University. Based on experiments where individuals are to solve artificial or real physics problems he tries to understand how varying personalities and cognitive abilities shape the problem-solving process. How are individuals that prioritize small changes different from individuals that go for more explorative attempts? Furthermore, what is the influence of being in a collective and seeing the behavior of others who are solving the same problem? Overall, the aim is to improve our understanding of how to organize problem-solving.
