A first and preliminary sight of the data (in preparation for publication) showing a new and entirely different methodology for measuring the (probably dysgenic) decline in simple reaction times over recent generations - extrapolated to the past century. This confirms the result of the previous study.

Note added: I do not suppose the above independently-sourced evidence means that 'the case is closed' and the substantial decline in sRT/ Intelligence has been established beyond all reasonable doubt. All studies are flawed, none are conclusive. I do, however, believe that this confirmation means the earlier study of substantial Victorian-Modern sRT slowing cannot be dismissed - and the hypothesis of substantial RT slowing/ IQ decline must now be taken seriously by honest and competent people, and therefore ought to be followed-up by further testing and evaluation.
