Social science has uncovered many fascinating aspects of human behavior, from how we think as individuals to how we act in groups. We know that humans are loss averse, emotional, habit-forming creatures. We mispredict the future and misremember the past. And yet, what social science is missing is a better understanding of how these phenomena (and others) change over time, in different cultures and regions, across gender and age.

By collecting a heaping amount of data (and increasing the size of our samples), we hope to unravel nuances in behavioral variations; we hope to detect the impact of minor differences that simply wouldn’t appear in smaller samples. The pursuit of this app is to collect an abundance of data from an abundance of locations all over the world, shining light on behavioral similarities and differences, from Antarctica to Zimbabwe. To do this, we need your help! Join our team of smartphone scientists and take on small tasks that will be “pushed” to you through the app.

On some occasions, you’ll be asked to give your opinion about various topics; you may be asked to predict the outcome of an experiment or to record your thoughts on anything from wealth distribution to peer influence. On other occasions, you’ll be sent out into the world to collect data; you may be asked to interact with a stranger or observe a scene and record certain details. Prepare to be surprised and delighted by the exciting research you will be a part of.

Brought to you by Dan Ariely and the Center for Advanced Hindsight, “(Sample) Size Matters” asks anyone with a smartphone or iPad to participate in a movement that transcends oceans and cultural barriers, gaining access to a wider range of information than ever before. Download the app now, and get started on your first mission!

How it Works:
- create an account
- complete your first mission by following the instructions in the app
- sit back and wait for the next mission to be pushed to you, and make sure to complete it before time runs out!
- keep track of your missions and your points earned for each experiment.

  • Wonderful idea

    by hugsid

    I'm a huge Ariely fan and am excited to see what possibilities this will bring. I'm really looking forward to seeing the results of these experiments. If you are not yet familiar with his work, I would recommend watching his TED talks and reading his books. They are fantastic!

  • Interesting concept

    by kklimuk

    Waiting on more experiments to come out and see what is up with it.

  • Programming is incomplete

    by Ahteeg

    I downloaded this to my iPad and had some fun trying answering some questions. The next time I tried to log in, it said my password was invalid, which is fine (I'm not great at keeping track of passwords), but there was no option to retrieve or reset my password. I tried every password I could think of and then gave up. Later I tried to open it on my iPhone, and not only did it make me start over with registering a new account (I didn't see a sign in option), there was a bug that kept saying I had skipped a question, even though I hadn't. This app is a great idea, but the programming is too frustrating to be worth it.

  • Missing basic stuff

    by Врунгель

    You can't reset password, for example.

  • Needs work

    by JWean

    Still needs work. Requires you to set up account or login to start. The setup account does not function and crashes.
