Dual N Back Results
Hey guys, I wanted to share my write-up on Dual N-back. It includes the science behind DNB as well as my personal results.
I don't have any hard data to back up IQ gains, but subjectively, it feels like I'm about +5 IQ points better for it, Lol.

Dual N-back is a deceptively simple looking brain game that is scientifically proven to:
- Increase concentration
- Boost working memory
- Increase fluid intelligence
Working Memory = Fluid Intelligence = Cognitive Ability
"Working memory" is interchangeable with â€œfluid intelligence.â€ Fluid intelligence is a good predictor of general cognitive ability.
It underlies many activities you might do on a daily basis:
- Mental math
- Reading and writing
- Learning new skills
Working memory gains from Dual N-Back proved to be linear in this study. As the numbers show, the more you train with Dual N-Back, the more benefits you reap.
Working memory training = more general cognitive ability in mice. More specifically, these challenges enhanced the Dopamine 1 (D1) receptors in the mouse brains. Thereâ€™s definitely some correlation between D1 receptors and mental health.
Dual N-Back has varying levels of difficulty. Everyone starts out on level 2. I played at least 3 games per day for 31 days.
Here were my average scores by the week:
Week 1 Dual 2-Back (90% accuracy)
Week 2 Dual 3-Back (60% accuracy)
Week 3 Dual 3-Back (80% accuracy)
Week 4 Dual 3-Back (90% accuracy)
The results I noticed seemed minimal, at first. But then I realized I wasnâ€™t forgetting what I was going to say in conversations. I didnâ€™t have trouble focusing. I could quickly process complex thoughts and memorize long sentences.
After taking a week off, I came back to the game. I expected at least some atrophy of my mental abilities.
To my surprise, Dual-3 Back seemed so incredibly natural that I had to bump up the challenge level to Dual 4-Back. Allowing a â€œrecovery weekâ€ seemed to enhance my gains even more!
Your mind is a muscle- use it often, for good things.
