5 year anniversary of discovering the rapid, severe intelligence decline in The West

It was just over 5 years ago on this blog that Michael A Woodley and I published the discovery of a rapid and severe slowing of simple reaction times over the past century-plus; and the interpretation that this implied an equally precipitous decline in general intelligence ('g') which has been missed by IQ testing.

I estimated the intelligence decline in England over c.150 years would be at-least (probably more) than one standard deviation (or 15 modern IQ points):

On my part, this led to a multitude of blog posts:

And the whole story was rounded-up in a book co-authored with Edward Dutton

On Michael's side, it led to a series of papers (one of which I co-authored) which - using multiple methods and measurements - are overall consistent with the proposed decline; and can be taken as confirmation of the thesis of that original blog post from Feb 28 2012.

The story of 'The Woodley Effect' was summarised recently on James Thomson's blog:

So, a lot has happened in half a decade - which is not a long time in science!
