Here’s a presentation I gave at the anniversary of Australian Policy Online which has been cunningly rebranded under its old acronym as Analysis and Policy Observatory. I gave a similar one at Kings College London a few weeks previously. Note that some of the slides may seem a little odd. That’s because I typically ‘build’ some of the slides to illustrate a train of reasoning. But I expect you’ll get the hang of it! If you like, you can download the slides from this link and build them while you watch. Some of the ideas presented are set out a two part essay here and here, further explicated here with some further thoughts here.
