Gwern’s Excellent Review And QSEU15

This week I was in Amsterdam at the European Quantified Self conference and it was an inspiring event. I have huge appreciation for Gary, Ernesto, Steven, Marcia and Kate for putting on a fantastic program. I always come away from theses events inspired to up my QS game.

Even before the conference kicked off, my post last week on the poor results from Bitter Melon really got everyone’s collective juices flowing. Some great comments and suggestions, with Gwern Branwen going above and beyond by reviewing my data and taking it through advanced mathematics using R. His work is awesome and I plan to conduct a full followup.

At the conference I had a chance to collaborate with Marco Altini in presenting both a breakout and a how-to session. I have been a fan of Marco’s apps for a long time and got a chance to meet him in person last year. This chance to collaborate was a real pleasure and I think the sessions went well.

I also met Dr. James Heathers (here he is on the Ben Greenfield podcast), an Australian skull ring wearing rock and roll scientist. He gave a great talk on the science of Heart Rate Variability (HRV) that included tips like voiding your bladder before taking a reading and how drinking water can significantly increase your HRV. I also had the pleasure of joining him for dinner and enjoyed a broad-ranging discussion that included his stories of research, observations on Quantified Self and a thorough evisceration of Sam Harris.  Good time.

At the conference itself there were thirty-seven talks and a much-improved conference format allowed me to catch them all. Wearables and the obsession with what technology can do for us seemed much muted in comparison with last year’s conference.

In the “all is connected” category, two presentations stood out for me. Justin Timmer gave a fascinating view of his tracking of 40 different variables over the course of one year. The big takeaway was that all his variables were connected and that each seemed to influence every other. Ahnjili Zhuparris gave a view on six months of her shopping, Facebook language use, & music listening behaviors during different phases of her menstrual cycle. A fascinating look at how much our underlying systems connect and effect the whole of us.

In the “surprising outcomes” category Robby MacDonnel presented data on how distracted he was while driving. Despite having judgments about the distracted driving of others, he found himself on his phone while driving over 20% of the time. It was a great talk. Rocio Chongtay was able to show how different music changed outcomes for her in as diverse a set of activities as programming and accuracy while firing a bow and arrow.

A useful session for me was on reading speed and neuro-technology. Kyrill Potapov’s talk titled “Finding My Optimum Reading Speed” outlined the use of Spritz reading technology and how with the help of his students he was able to test increases in reading speed without a reduction in comprehension. Definitely a technology I am going to play with.

A breakout session on neuro-technology had a lot of skepticism in it regarding any of the existing technologies, and TDCS was particularly viewed with some hesitation. I’ve started a TDCS experiment though I am rethinking it now. There were some strong opinions on binaural beats and I’ll withhold what I heard until I publish my A/B test on the effectiveness of Brain.fm’s meditation beat on my Muse calm scores.

So it was with Gwern’s Excellent Review and QSEU15. An action packed quantified self week.
