Which of the following is true regarding the legacy of Francis Galton?

A) Although his ideas have been discredited, his use of statistical methods to measure and study behavior has had a lasting impact on scientific psychology.
B) While many of his ideas are still considered valid, Galton failed to use scientific methodology.
C) Both his ideas and methodology are still considered valid today.
D) Although important in his time, Galton had almost no lasting impact on scientific psychology.

Answer: A
Rationale: Galton's excessive focus on the role of genetics in determining behavior, and his belief in the genetic superiority of some individuals are no longer accepted by mainstream psychologists. However, Galton's use of statistical methods to measure and study behavior and mental processes has had a lasting impact on how psychological research is conducted.
