I learned a lot....most importantly, the apparent lack of understandable information (for judges, lawyers, etc.) [in a single source] regarding basic psychometrics and psychological measurement and how this knowledge void may result in possible improper interpretations and decisions. It is my hope to develop this blog as a resource for individuals involved in such cases. The goal will be to provide balanced and up-to-date information on issues related to this important topic. This will include, but may not be limited, to:
- Intelligence testing practice
- Intelligence testing interpretation
- Differences between intelligence tests
- Relevant theoretical information about intelligence theories
- Controvesies and issues
- Findings of particular cases, court decisions, etc.
- Glossry of understandable terms
- Scholarly journal articles that address this and related issues
- FYI notification of relevant professional publications
- Important psychometric, measurement, and statistical issues
- Relevant research on intelligence tests and research (e.g., Flynn Effect)
- Other issues as they emerge.
This blog is meant to be specialized and will not deal with all issues related to IQ testing and/or the death penalty. There are a ton of websites that provide this information. The intent is to focus primarily on psychometric measurement issues and research related to intelligence testing that may have bearing on capital punishment cases for individuals with an intellectual disability. Also, this website is not pro- or-con re: the death penalty. My goal is to stay issue neutral and not advocate. If some of the posts tend to sound like I am preaching or advocacting, it most likely is due to my fervent passion in the defense of good psychometric and theoretical-based psychological testing and the need to educate others, often via highlighting what I think is bad practice. If I am guilty of any bias, it is not intentional and is due to my strong belief in the science of psychological measurement, a science that can be abused and misunderstood.
I will not comment on details of the case that piqued my interest. Lessons learned from that case will appear as more general posts sometime in the future.
It is my goal to provide objective professional information free from my personal beliefs re: capital punishment.
That's the plan.
