As a long-time meditator, Peter Lewis had a suspicion that meditation could improve brain function, so he conducted a self-experiment and enlisted a few other individuals to help test his hypothesis. By using an arithmetic testing application, a timed meditation app, and an ABA research design he was find out that there was some support for meditation improving his brain function. However, other participant’s results weren’t as supportive. Watch Peter’s talk, presented at the 2013 Quantified Self Europe Conference, to learn more about his process and hear what he learned by conducting this experiment. We also invite you to read Peter’s excellent write up on Seth Robert’s blog: Journal of Personal Science: Effect of Meditation on Math Speed and the great statistical follow-up by our friend Gwern.
Update: 10/19/10 – Study is now open to users at http://genomera.com/studies/butter-mind
Will eating one of these fats improve your math performance? Based on Seth Roberts’ butter and math
study, recently presented at a Bay Area Quantified
Self Show & Tell, during which Seth ate half a stick of butter each day and performed better in math, we expect the answer to be yes.
Seth was able to reduce his time by 30 milliseconds. Will others who try a similar experiment experience the same change?
In the Butter Mind study, to be run from October 23 – November 12, I will test the hypothesis that butter improves math performance. (note: there has been a slight shift in the dates.)
This study is meant to
mimic Seth Robert’s study, with the addition of a coconut oil group.
Many thanks to Seth for his advice and help getting this started!
Why the addition coconut oil? I have a pet theory that the cognitive enhancement Seth received may be from the high concentration of Medium Chain Triglycerides in butter, also present in coconut oil, which has been linked to positive effects on those with Alzheimer’s Syndrome. Seth has not tried coconut oil, so cannot report on its effects on his math scores.
Obviously, no study is perfect – and this one is no exception! It’s a test I was interested in trying myself after seeing Seth’s presentation — but I realized it would be far more fun and interesting to include others! This will be fun for me, and I hope for you, too. At the very least, will get data from a group over a 21-day period, but we may even get a few curious surprises.
I am currently looking for Butter Mind participants, who will perform a math test daily for 21 days and be in one of the following groups: butter eaters, coconut oil eaters, and controls, who will eat no additional fat but will perform the same math test as the fat-eaters.
To qualify for the study, you must be willing to eat 4TBS of butter or coconut oil (sticking to the same one) – or nothing extra – for 7 days and do a 32 problem simple math test for 21 days. You must have access to the internet to submit your scores.
will be randomly selected to be in the Butter, Coconut Oil, or Control group
- Participants will be responsible for purchasing butter or coconut oil, if in either of those groups
- The study
will take place for 21 days: from Oct 23 – Nov 12
study will be divided into 3 sets of 7 days
o Part I. Oct 23 – 29: Perform simple
math quiz daily + No additional
o Part II. Oct 30 – Nov 5: “Fat.” Perform simple
math quiz daily + Butter OR
Coconut Oil. For Controls, just the quiz.
o Part III. Nov 6 – 12: Perform simple
math quiz daily + No additional
- Non-control participants
will ingest 4 Tablespoons of either
Butter or Coconut Oil during the “Fat” portion of the study
will be asked to share lifestyle information before the study and asked to join an online group to track their data. Extra sharing (thoughts, epiphanies) is encouraged but optional.
will statistically analyzed, hacked and visualized (and new studies brainstormed) during Science
Hack Day, November 13-14, Institute
for the Future. www.sciencehackday.com. You can join for the Science Hack Day portion only by registering here.
results will be posted to the QS blog throughout the study
- Interested participants will receive a form requesting data on lifestyle factors several days before the study begins. I will update this post with a link to the form when it is ready.

Here is a great presentation by Tim Lundeen from the recent QS Show&Tell. Tim is running some interesting self-experiments on diet and cognition.
Diet and cognition is a topic of such obvious interest that it regularly breaks through into the popular press and the science blogs. For instance, eating blueberries and walnuts make rats smarter.
Tim was specifically inspired by the many posts Seth Roberts has made about the benefits of omega-3 fatty acids. Tim uses a simple test of cognitive function as his dependent variable: he gives himself 100 very simple math problems and records the time it takes to complete them.
Here is one of the graphs Tim made in his self-study. The y-axis is the time it take to complete his 100 problems. On about day 80, he upped his dose of DHA from fish oil.
