Editor's note
Did you know more than 60% of Kentucky Derby jockeys are Latino? Two top horses in todayâs big race also have Latin American bloodlines: Game Winner, a 2019 Derby favorite, and his half-brother Vekoma are the offspring of a prized Argentine thoroughbred. Sports historian Gabrielle Kuenzli from the University of South Carolina uncovers Latin Americaâs [long and winning tradition at the Kentucky Derby](.
On Sunday, many people will celebrate Cinco de Mayo â and nurse their Kentucky Derby hangovers â with margaritas and nachos. But only 10% of Americans know the holidayâs origins. University of Southern California, Dornsife anthropologist Kirby Farah hopes to change that. She tells the story of the [famous David versus Goliath battle]( that led Mexicoâs first indigenous president to declare a national holiday.
And will you visit a psychic this weekend? Tune in to a political pundit? Check on your finances with a money manager? Cognitive anthropologist Manvir Singh asserts that the social and psychological pressures that [have always given rise to shamans]( over the ages also produce these modern versions in the contemporary, industrialized West.
