  • Website Preferences Around the World

    March 20, 2014

    How do you feel about Naver.com, a search engine shown in the screenshot below. Would you say it is badly designed?

    Most Americans would feel alarmed at the sight of Naver.com. But many people prefer this design over the simplistic look of Google. In fact, Naver’s colorful design and high information density help make it the most popular search service in South Korea.

    Research has repeatedly found that people’s visual preferences vary widely. This is just as true in the online world as it is in the offline world. Challenging the notion of a one-size-fits-all universal design, we find that some people like colorful, complex websites, while others prefer simple and clean designs, and still others prefer something in between.

    You might argue that it doesn’t matter what a site looks like. But it does matter! If we find a website appealing, we are more likely to buy one of its products [1], and we perceive it as more trustworthy [4, 5]. A more fitting design can even increase our satisfaction with the site, and our work efficiency [7].

    But who likes what? Answering this question is difficult. Our online preferences seem to depend on individual and demographic differences, such as personality, gender, or age [2, 3, 6, 7]. 

    To find out how our visual preferences differ, we launched a study on LabintheWild. We asked people to rate a set of websites based on visual appeal. Over the course of a year, we collected approximately 2.4 million ratings from almost 40 thousand people around the world. We used this data to study how people from different countries, educational backgrounds, ages, and genders respond to a website’s colorfulness and visual complexity.

    And here is what we found:

    • Overall, visual complexity had a greater effect on participants’ preferences than colorfulness did.
    • Most participants did not mind a low level of visual complexity, but disliked highly complex websites. 
    • The average participant preferred relatively colorful websites.
    • Participants older than 40 found plain, colorless websites less visually appealing than younger age groups. This was especially true for participants older than 50, who really seemed to dislike the simple and colorless websites in our dataset.
    • Independent of age, women preferred more colorful websites than men. Our female participants also had a stronger negative reaction to very simple websites than males did.
    • In general, male participants preferred websites with saturated primary colors on a gray or white background (see the screenshot below). Female participants preferred more homogeneous color schemes that avoided stark color contrasts (see the second  screenshot below).

    We also looked at how aesthetic preferences vary across different countries. Prior to this analysis, my stereotypical understanding was that people from Germany and Switzerland prefer simple and colorless websites, while people from China and other Asian countries prefer colorful and complex ones. But I had to correct my stereotypes, at least to some extent. For example, we found that people in Finland, Russia, and Poland liked websites with even fewer colors than the Germans and the Swiss. Similarly, people from Malaysia, Chile, and Macedonia preferred much more colorful sites than the Chinese, whose preferences actually don’t seem to be that different from those of people in the U.S.

    You can have a look at the country overview below to see more details about each country’s preference for levels of colorfulness (red lines) and visual complexity (blue lines).

    We also found that countries close to each other seem to often share similar preferences. For example, the neighboring countries Finland and Russia preferred the lowest visual complexity and colorfulness of all countries, followed by Sweden.  Participants from Macedonia, Serbia, and Bosnia and Herzegovina—all countries that were part of former Yugoslavia—had very similar preferences for highly colorful websites. In addition, the Northern European countries in our dataset (Denmark, Switzerland, France, Germany, Sweden, Austria) preferred a lowerer colorfulness than Southern European countries, such as Italy, Spain, Greece, or Romania. Northern European countries also preferred a lower colorfulness than Asian countries, such as China, Singapore, and Malaysia.  Hong Kong and Japan preferred a lower colorfulness than other Asian countries, but higher than Northern European countries. All of the English-speaking countries (Australia, New Zealand, Canada, United States, Ireland, and the United Kingdom) also preferred a higher colorfulness than Northern European countries.

    These results could suggest that countries with a regular exchange of cultural values, perhaps due to migration, share similar website preferences. We are looking forward to investigating this further. 

    Thanks to all our participants for taking part in this study! We cannot thank you enough for your contribution to science and to making it a little less WEIRD!

  • The first results from the age guessing experiment: how clicking performance changes with age

    October 12, 2013

    In the spring we conducted an experiment, in which participants clicked on several dozen dots (like the ones below) and at the end of the experiment our system made a prediction of each participant’s age based on their performance.

    a screen shot of the age guessing experiment

    We were overwhelmed by the amount of interest this experiment received, by how many people were sharing it, and how many newspapers around the world reported on it. In fact, even our servers were sometimes overwhelmed: On several occasions I had to turn back to the office to restart the server after it had silently crashed underneath my desk.

    When we started analyzing the data in early June, only a few months after launching the experiment, more than 500,000 people from 218 countries and territories participated.  The map below shows where our participants came from (darker color means more participants).  

    map showing where our participants came from

    If you were one of the participants, we thank you!  With your help, we were able to gain new insights into how clicking performance differs depending on age, gender and country. Over the next several weeks, I plan to write up some of the most interesting results and share them with you. 

    Initial results

    Today I will start by telling you how the overall clicking performance changes with age. This is only one of many measures that we recorded from the experiment to “guess” people’s age, but arguably a very important one. And if you are really interested in how exactly we measured the performance, we have the geeky details at the bottom of this post.

    But let’s talk about the results. The graph below shows the average performance per age between 5 and 85.  The error bars show the 95% confidence intervals – the smaller the error bars, the more reliable the result.

    And here we are already with some bad news for you. If you are over 17 years of age, you have seen your best times, at least in the mouse-clicking world. On average, 17-year olds are the most efficient clickers. Starting in late twenties, we all begin to very steadily get a little slower every year.

    If you are under 17 years of age, the news is great. Children and adolescents get faster very quickly from year to year. This is actually very important for those of us building software for children because it means that even in a single classroom we are likely to see children with very different clicking speeds.  Finally, you can see that the clicking efficiency of young children (5 through 7 year old) is very similar to the clicking efficiency of our participants aged 80 and older.

    Some technical details

    How exactly do we measure the clicking performance?  You might have noticed that it is much easier (and therefore faster) to click on big things than on small things.  It is, of course, also faster to click on things that are nearby than on those that are far away.  Because our experiment was designed to adapt to the size of the screen on which it was displayed, everybody saw a slightly different version of the experiment: for some, all the dots were close together, while for others the dots were further apart.  

    To make it possible to compare how different people did, even though each completed a slightly different task, we used the concept of Throughput (sometimes also called Index of Performance) developed in 1954 by a psychologist named Paul Fitts.  Paul Fitts developed an equation for measuring a difficulty of a clicking task that depended on how far one had to move and how big the target was.  Of course, there were no personal computers in 1954 —- what Paul Fitts was studying was how quickly and accurately people could point with their fingers, but, as it turns out, his findings apply to mouse clicking as well.  His throughput measure is simply the difficulty of the task divided by the time it takes a person to complete it.  Throughput is measured in bits per second.  We realize that saying that a person has a “throughput” and measuring it in bits per second is very geeky, but it works.  Think of it as speed: the higher the better.

  • Making science less WEIRD

    August 19, 2013

    A vast amount of research findings out there relies on studies that were conducted with American undergraduates. In fact, most of what we know about people’s perception, cognitive skills, or their behavior is derived from such studies. Yep, we know pretty well how American undergraduate students work. 

    But we have only found out recently that American undergrads are not necessarily representative of the world’s population. In fact, they are quite a WEIRD species: Western, Educated, Industrialized, Rich, and Democratic. (See Henrich et al.’s paper (PDF) for some excellent examples on how WEIRD some of us are.)

    We totally agree that science is a little bit WEIRD. This is also why we have proposed a panel presentation at the SXSW conference next year to show how much better we can do by collecting larger, and more diverse samples on LabintheWild.org, TestMyBrain.org, and GamesWithWords.org. 

    In order to be selected, however, we need your vote

    Thanks for your support and for helping science become a little less WEIRD. :)

  • A test of trust

    July 19, 2013

    We design studies for LabintheWild based on this central idea: we trust you. Whether you are a new arrival or a long-time participant, we trust your responses to be an honest representation of your beliefs and perceptions of the Web. We also hope that you trust us - to use your information carefully and to provide a fun experience where you can learn more about yourself.

    But what about other websites? Trust is a decisive factor for engagement when users go online, so it’s important to understand what in a website makes users decide - even within the first few moments of visiting that site - whether to stay or leave in search of greener (and perhaps safer) pastures.

    With this question in mind, the LabintheWild team is delighted to announce our new Trustworthiness Test, where you can use your intuition to rate websites based on their trustworthiness. We’re interested in testing out claims from previous studies that we can make judgments about websites within milliseconds (!) of seeing them for the first time. We are also interested in investigating what people perceive as (un)trustworthy and how this differs around the world. At the end of the test, you’ll see how well your intuition of trustworthiness matches reality. Click here to take the test, and stay tuned for our findings!

  • New results on predicting your website preferences

    May 22, 2013

    Internet users make lasting judgments about a website’s appeal within a split second of seeing it for the first time. This first impression is influential enough to later affect our opinions of a site’s usability and trustworthiness.

    Because the first impression counts, we developed an approach to predict whether users will find a website appealing. Given a website’s screenshot, we are now able to 

    • tell how colorful users perceive the site,
    • compare the level of visual complexity of one site to another, and
    • predict a website’s appeal.

    image

    In the future, we would like to enhance this approach to work on a more individual level, for example to enable a comparison of the preferences in various cultures. But of course, we need your help. Please participate in our ongoing study!

  • How it all began...

    July 17, 2012

    Many people have asked me why LabintheWild is mainly about exploring how we are different and similar in our cultural preferences. I guess one of the reasons is that I have always liked to travel and see how people around the world differ from each other. What I find fascinating, and what my research has shown, is that these differences also translate to the online world.

    I first noticed this around 7 years ago when I lived in Rwanda for a while to develop an e-learning platform for agricultural advisors in the country. Being completely ignorant about cultural preferences, I designed the user interface the way I thought was nice and intuitive. I guess my German background must have convinced me that “nice” means plain, very few colors, and very little information. Whatever it was, my Rwandan co-workers didn’t like it at all. It took me a while to understand that they preferred more colors, a higher complexity of the user interface, and a linear structure that would lead them through each lesson step by step. But why? Why doesn’t everyone in the world have the same preferences? One reason might be that everything in Rwanda is a little bit more colorful. At least in comparison to Northern Germany! Their clothes, the nature, … the colors make everything look a little more cheerful.

    In an attempt to explain some more preferences, I also visited a few local schools and noticed that in those schools, the education was mostly teacher-centered and students focused on following instructions. Could this maybe explain why my co-workers favored more guidance in the e-learning platform?

    Well, years have past and answering these questions has proved to be a little more complicated than I originally thought and has evolved to be my central research interest. What I have found so far is that online cultural preferences are quite complex—but they give a unique and fascinating view into who we are and how we experience today’s global village called the Internet.
