Re: Gene V Glass • Why I Am No Longer a Measurement Specialist
When I was learning research statistics, the standard cautionary tale on construct validity featured the foibles of Phrenology, the onetime pseudoscience that sought to psych out a person’s aptitude and character by measuring the bumps on his or her head to the last decimal place.
It appears that Phrenology never dies, it just fads away in ever new fashions.
