Now Testing: Dual N Back

Can brain training increase intelligence?

Let’s test it.


Dual N Back:

This field of research is still relatively new, and results have been mixed, but many studies suggest that brain training challenges (such as dual n back) can increase your IQ / fluid intelligence.

“Fluid intelligence measures how people adapt to new situations and solve problems they’ve never seen before.” (Alexis Madrigal, wired article, 2008)


  • Memory Improvements
  • Pattern Recognition / Connectivity
  • Faster Problem solving
  • Improved Focus / Attention


In the end, there’s only one way to know for sure — Test it for ourselves.


I’ll be testing dual n back with —

20 round (about 20 – 25 minutes) per day, for 4 weeks.

I’ll periodically post my thoughts and results as I go (so be sure to check in!)
