Regular readers may recall that I once conjectured that I could improve my chess by wearing a dress. Well, you’ll be pleased to hear that I’m finally getting round to testing this. Day 1 was allocated to the control group, and I scored 1.5 out of 4. Day 2 was allocated to the intervention group, and I scored 2.5 out of 4. Pretty promising! After day 40 I’ll see whether the intervention days are significantly more successful than the control days. I’m also gathering some other data to see if there are any more patterns I can test in future work. I’ll let you know how it goes, but don’t put it your diaries as I’m quite busy at the moment and the trial days may not be consecutive. Are you excited to find out? I know I am!
