Under this OSF project, you may download 1) Weight IAT data sets with IAT score computed, self-report data labeled, and demographic information by year or for all years; 2) codebooks associated with each data set; 3) experiment materials and description of procedure from countries in which Weight IAT has been run.
The public data sets don't have participants' zip code/postcode to protect privacy. If you are interested in the zip code/postcode data, you may submit an ethical approval from your institution or organization. Upon verification, you will be able to download the zip code/postcode data.
Please contact Project Implicit at admin@projectimplicit.net for any question, comment or zip code data request.
