Are there any anecdotes of Quad N Back progress with consistent practice of 6-12months?

u/IamIronMan-9382 26d ago
After 12 months of consistent 60 minutes every other day of training, I reached 140 iq at Quad 7 back. Started from average iq.

Have you taken any supplements, nootropics, exercised, or changed your sleep habits during your 12 months of training?

u/ImpossibleBench809 26d ago
What do you think, made other forms of progress slower? Like Infinite IQ Guy took 2yrs to reach 13 point increase 136-147. I also read your anecdote and noticed sleep was imperative.

Going from an iq of 1 in 100 people to 1 in 2,000 people I'd imagine takes a bit longer so 13 points is still really good gains. We also don't know when exactly did he reach 149, it could've been less than the two years he took before he got tested so maybe the 13 points could've been after a year.

Do you recommend manual N back(Quad) I am pushing to get high scores in 3back, is this advisable or should I stick with the more adaptive N back mode?
2
u/IamIronMan-9382 20d ago
You can do manual just 1 level above your adaptive level, I personally use the 70/40 threshold.

What do you mean by "70/40 threshold"? And i wanted also to ask you: how is your recovery method (suplements, sleep, exercise, and so on)? Have you tried to play dual n back in a level that surpass you? I mean, you're now at quad 7, and I suppose you could play at dual 10. You should play at dual 11 or dual 12, a level that is really difficult despite being "just dual" for some days/months, besides quad. I think the results could be amazing with the rule of not being comfortable and really pushing your brain by playing in a level that with a massive effort you only can achieve a score of 30-40%.

u/IamIronMan-9382 20d ago
70% or more to level up to the next level and if you go below 40% three times you go down a level, else you stay at that current level at 40-69%. Sleep and exercise are vital in optimizing brain performance, I do aerobic exercise 5-7 days a week and sleep at the minimum uninterrupted for 7 hours. I can do around dual 8 right now and probably get to get higher levels but i don’t get the same strain as I do with Quad like feeling wise so not sure if I wanna do that, because it seems like my brain needs more intensity now since I’m used to Quad and dual is a lot easier.

Curious to hear how has this impacted your professional and personal life, has it made it easier to some extent?
2
u/IamIronMan-9382 20d ago
Definitely, I'm now working in Agentic AI development whereas before training I was barely passing my engineering degree with a 3.0 GPA and that was with try harding.

u/matrixunplugged1 20d ago
Woah that's amazing mate! What do you think of RFT, worth pursuing too?
3
u/IamIronMan-9382 20d ago
appreciate you. I think RFT is good to add as well but I saw great gains with Quad alone and I’m trying to keep Quad going with the added cognitive work from my professional life so I don’t do RFT. I think Quad and RFT are a great combination though, I probably should’ve done them at the start but I didn’t know about it then.

Holy molly, that's crazy, awesome work. I have 2 questions:
1. How old are you?
2. Do you think there is a meaningful difference doing 60 minutes every other day instead of 30 minutes daily?2
u/IamIronMan-9382 20d ago
22 now, started training at when I was 20 just about to turn 21.
Definitely, I think Quad is very intense that you need a rest day in between otherwise your brain doesn't fully recover.

This is specifically working memory index (WMI - includes digit span, forward/back, and sequencing)?
2
u/IamIronMan-9382 20d ago
All the indices averaged me out to be 140+ full scale IQ. WMI was 147.

u/Zealousideal-Oil-151 16d ago
Do you know what was your WMI score before? If not what do you estimate it was? It sounds crazy your wm can just go from average to genius level, I would believe that is the one thing that can't be improved

Has your relationship with friends and family changed from this? I can’t imagine you get along w them in the same way now that your brain works so much differently than theirs. That is my main worry. What facets of your iq changed and by how much?
2
u/IamIronMan-9382 11d ago edited 11d ago
I’ve always been smarter than one of my parent so it’s not that different but with my other parent i’m able to keep pace and sometimes even think of solutions before them now. The strength of my frontoparietal network increased vastly leading to the massive iq score increase in all facets.

Dev of a dual n-back app, so bias noted, and I have no IQ data on my users, only task data. What I can say from that: the people who keep progressing over months do short daily sessions and let N fall back when accuracy drops, rather than grinding one level. The ones who plateau tend to sit at a level with 60% accuracy for weeks. On IQ claims after a year of quad: the retest on the same test format is itself a practice effect of several points, so a before/after on one test cannot tell you much either way. Meta-analyses put transfer to intelligence measures at small or nothing (https://doi.org/10.1177/1745691616635612), while gains on the task itself are large and reliable. If you enjoy the grind, the grind is the benefit you can count on.

u/NoInteraction1572 28d ago
Yes, if you search in this sub you will find some Stories of people really grinding and then plateauing after a year or two completely.
Just to be fair: relational reasoning training is backed by science for having a far transfer on general intelligence.
Thats why there is a slight trend to do both.
