The Flynn Effect report series: A biref history of the Flynn Effect--It was NOT given birth by Atkins V Virginia (2002) SCOTUS decision: IAP AP101 Report #8


Another new IAP Applied Psychometrics 101 report (#8) is now available.  The report [A brief history of the Flynn Effect: It was NOT given birth by Atkins v Virginia (2002) SCOTUS decision] is the third in the Flynn Effect series, a series of brief reports that define, explain and discuss the validity of the Flynn Effect (click here to access all prior FE related posts at the ICDP blog) and the issues surrounding the application of a FE "adjustment" for scores based on tests with date norms (norm obsolescence), particularly in the context of Atkins MR/ID capital punishment cases.  The abstract for the brief report is presented below.  The report can be accessed by clicking here.

Abstract for third report.
This is the third in a series of brief reports to define, explain, and summarize the scholarly consensus regarding the validity of the Flynn Effect (FE). This report presents a brief historical summary of origins of the Flynn Effect (norm obsolescence). Historical facts indicate that the concern for IQ norm obsolescence and the concept of an IQ score adjustment procedure pre-dates the U. S. Supreme Court Atkins v Virginia (2002) MR/ID death penalty decision. The series will conclude with an evaluation of the question whether a professional consensus has emerged regarding the practice of adjusting dated IQ test scores for the Flynn Effect, an issue of increasing debate in Atkins MR/ID capital punishment hearings.
