Intelligence itself is a subjective concept. That's why IQ tests are culturally specific.
Came across this great piece on the subject of Watson's statement that pointed out that in 1869, Darwin's cousing Francis Galton wrote that he felt:
" '... as a savage would feel in England'; he felt scared and alone. His scientific instruments, however, imposed a rational order onto an unknown place. They comforted him and made him feel in control. His hosts might have felt differently. Many cultures more readily embrace mystery and would view Galton's feeble attempts to order nature as itself a senseless endeavour. Intelligence, like science, is local and cultural."
