Do you agree with the psychologists who consider various constructs used in psychological investigations, such as intelligence, optimism, and attractiveness, to be measured on a ratio scale? Why or why not? What are some properties of the other scale of measurement that may or may not apply to the constructs? If these constructs cannot be measured on ratio scales, which scale of measurement is appropriate? Why?
