Reasons to get one's ducks in a row

Reading Norman Blaikie's Approaches to Social Enquiry, I was struck by how long it was taking me to remember the four different research strategies outlined on page 8. I made up new pnemonics every week to recall the features of abductive and retroductive reasoning, while inductive and deductive reasoning looked worriedly on. Fed up, I made this. I hope it helps you too. (Whatever you think about these strategies.)
