A Survey about Spending

June 13, 2016 BY danariely

As spending money becomes easier (think of credit cards, Apple Pay, and Google Wallet, among others), we have more opportunities to spend our money well, and to spend it not so well. In collaboration with Qapital, we have made a survey to learn about what kinds of purchases people feel good about, and what kinds they regret. Note that this link and survey is secured by the highest possible internet and bank standards.

Please help us by participating in this short study and reflecting on your past transactions. We will randomly choose some participants to get the chance to have a 30-minute chat with me. You have our immense gratitude.

(Sample) Size Matters: New App Release!

June 20, 2013 BY danariely

a research app for smartphone scientists on the go

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.

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

  1. create an account
  2. complete your first mission by following the directions in the app
  3. sit back and wait for the next mission to be pushed to you, and make sure to complete it before time runs out!
  4. keep track of your missions and your points earned for each task
