The research focuses on whether the grey man can anticipate your thought patterns. The next time you click “YES" you will see a rotating circle of pink spots. There will be a small black cross in the centre. • While the grey man thinks you’re following the moving pink spot, they will all stay pink. • When he thinks you’re looking at the black cross, he'll turn one of the spots green. • If he believes that you’re focusing continuously on the black cross, he will slowly remove   all the pink spots and leave one rotating green spot. Click "YES" when you're ready, otherwise click "NO" to exit.
