I just got a chain email forwarded to me. Nothing to do with luck, life or death, but psychology.
You do a series of simple math problems like 53+22, 12+15...there are about 5-7 of them. At the end is the exclamation, "Now think of a tool and a color!"
98% of people think of a red hammer.
I thought of a blue wrench.
This stupid email never defined us 2% minority, although I have a feeling it explains many of my academic difficulties.
