As an investigator of the human mind, he founded psychometrics and differential psychology, as well as the lexical hypothesis of personality. He devised a method for classifying fingerprints that proved useful in forensic science. He also conducted research on the power of prayer, concluding it had none due to its null effects on the longevity of those prayed for.[7] His quest for the scientific principles of diverse phenomena extended even to the optimal method for making tea.[8] As the initiator of scientific meteorology, he devised the first weather map, proposed a theory of anticyclones, and was the first to establish a complete record of short-term climatic phenomena on a European scale.[9] He also invented the Galton whistle for testing differential hearing ability.[10] Galton was knighted in 1909 for his contributions to science.[11] He was Charles Darwin's half-cousin.[12]

Garvan, "I appointed therefore the mother guardian, who is properly so by nature and nurture, where there is no testamentary guardian.")
^English usage is based on a tradition going back to medieval literature, where the opposition of nature ("instinct, inclination") norreture ("culture, adopted mores") is a common motif, famously in Chretien de Troyes' Perceval, where the hero's effort to suppress his natural impulse of compassion in favor of what he considers proper courtly behavior leads to catastrophe.
