Status of these new chapters

These chapters have been drafted in anticipation of a forthcoming 5th edition of Modern Psychometrics, once loosely projected for around 2030. In today’s fast-moving AI environment, however, waiting that long no longer makes sense—and neither would waiting until 2027. The relevant ideas are live now, and the interaction between psychometrics and AI is evolving quickly enough that the writing needs to evolve with it.

These chapters are intended as methodological interventions, not final position statements. Their purpose is to bring psychometric concepts and constraints into clearer contact with contemporary AI practice—and, equally, to clarify what psychometrics can learn from the ways AI systems now behave (especially in adaptive and interactive settings).

Where appropriate, revisions will be made and new material added. The chapters are therefore part of an open, ongoing conversation about how psychometrics should respond to new technologies. This draft may be cited, provided it is treated as a developing contribution rather than a settled text.
