Before
you think

This is a research project run by researchers at Leiden University. You will play a short game that helps us understand how people think. Your data will contribute to real scientific research. In the game, you will sort words and images into categories as quickly and accurately as you can. After the game, you will see your score and learn more about what it means.

• Voluntary: You can stop at any time by closing the page
• Anonymous: We do not collect any information that could identify you. Anonymous data will be stored on Leiden University servers for 10 years.
• Risk free: The game is harmless

At the end of the game, you will see your personal score and receive information about implicit bias and what it means, including what you can do about it. You can also share your score with friends and invite them to play.
