brainmaxxing or the art of failing better

Well, I don’t usually post about personal stuff, but hey, hoomanity (and me) deserves something different every now and then.

Turns out I’m honored (and slightly amused) to share1 that I recently joined Mensa. *play doom_eternal_theme.mp3 💀

Here, I wanted to describe my experience and expectations, as well as some related personal background.

mens-what?

Mensa is this organization for people with high IQs. To enter you need to take a in-person test and score in the top 2% (98th percentile), which is two-sigmas away from the mean.

It started in the 40s in the UK and started in Spain around the 80s. Since then there are tons of replications in different countries. Their mission can be summarized as:

1. identify and promote human intelligence for the benefit of humanity.
2. encourage research on the nature, characteristics, and uses of intelligence.
3. provide a stimulating intellectual and social environment for its members.

my background

[!NOTE] spoiler I was not the typical gifted kid. At all.

Ever since I was a kid, I’ve loved making plans about everything. I’d want to repair a bicycle and would spend more time planning, making budgets and drawing sketches than actually doing it. I’m an only child, so I spent a lot of time by myself and could stay focused for hours in my own world2. However, I never considered myself an introvert. I’m a pretty social person.

I was also a terrible student. Not the kind who gets bored because the level is too low or the content isn’t challenging — I simply didn’t care about school. I never paid attention and failed an obscene number of subjects. Every year I ended up carrying a ton of subjects over to September, and then suddenly passed all of them3. TBH, I’m not proud of that phase of my life. It felt like I was wasting a lot of time and energy. It was also quite frustrating for my parents (and now that I’m a dad, I can empathize with that much better).

Then my father taught me programming when I was 13. That clicked! I became obsessed4 with it, and I spent all day in underground forums taking part in performance contests to see who could implement the fastest algorithm in VB6.

After high school, I decided to first study an HNC in web development, with the plan of starting uni afterwards (perhaps software engineering). However, I got hired at my internship, so I decided to keep working and put the uni plans on hold.

Years later I did start studying at UNED, but a BSc in philosophy (plot twist!). There I managed to get several honors while working full-time, plus doing some freelance collabs on the side. I was particularly fascinated by the analytical stream: logic, philosophy of science, etc. I was living in the UK at the time. That was an intense period of my life, but I remember it with some nostalgia.

In order to prioritize my career, I put the degree on hold5. I hadn’t taken it up with a career focus in mind, for obvious reasons. However, I think it had an indirect positive impact on my career in terms of structured reasoning, writing, creativity, etc.

Then I pivoted from development to cybersec, then to offsec specifically, and my linkedin tells the rest of the story. Along the way I failed miserably (still do, but with style 😎) at tons of projects, but they somehow contributed to who I am today. For instance, years ago I built an algotrading setup, and it was a nice excuse to learn statistics and probability, as well as how to design and implement high-frequency, data-intensive systems6.

To wrap up, I’ve never considered myself a particularly gifted individual. More like someone with decent processing power who’s willing to spend an unreasonable amount of energy on the stuff he enjoys.

why i tried

There were two main factors that motivated me to take the Mensa test.

First, my older son. He is currently ~4 years old, and I think he is showing early signs of giftedness: extraordinary memory, a complex sense of humor, musicality, the ability to focus for long periods of time, etc. But well, I’m his father, so I’m probably super-biased. I believe there are more parents of gifted kids than actual gifted kids, kek. At least it was enough to make me question it, since there is a decent heritability factor.

Second, I discovered Javier Recuenco. He was a Mensa Spain ex-president. I discovered him thanks to Heavy Mental podcast, where he talks about a wide range of topics. I love his communication style because he is not the typical nerd, but actually exposes complex stuff in a very aproachable way (a la Feynman, but with more sideburns)7.

the access test

I took the Mensa online test, then the paid online version called T2, which is supposed to be more accurate. Since I got decent results in both, I decided to give the in-person test a try. They arranged a session at a public library. The very same day, they corrected the test and I got accepted! 🎉

Something to highlight is that the exams are culture fair. Mensa is not politically, sexually, or culturally biased. The exam aims to capture your raw fluency in identifying patterns across different contexts and forming abstractions that relate ideas. Due to time constraints, you essentially have only a few seconds to connect the dots and mark your answer. I confess it made me sweat.

motivations

I joined Mensa for the following reasons:

• networking: we are trained with the same dataset. And as soon as you get older, you’re somewhat limited in making new connections. Here the premise is quite interesting: you meet people you share something in common with (high IQ), but they can be virtually of any background, profession, etc. I find that very enriching.
• conferences and events: they organize recurring conferences that are quite interesting. Most of them are uploaded to YT. Low-key, I’d been reviewing them for a while before actually joining.
• SIGs (Special Interest Groups): a fancy term for forums that gather people with shared interests, but for some reason it sounds cooler here. They also organize meetups every now and then.
• occasional discounts: I noticed there are some discounts for members, for instance on board games.
• bragging rights: I have a super fragile ego; this is a way of being able to sleep at night, kek.
• job opportunities: Also, high IQ often correlates with better job performance. So a potential employer (not currently looking for a change, HR guys) would value that. There is also a specific job board handled by Mensa Spain, btw. This is controversial but I don’t care: I think the controversy is born from the misunderstanding that IQ is everything (more on that later).

iq is not everything

I’m not a big believer in IQ as the ultimate indicator of pure intelligence, but it’s just another variable in the equation.

Having a nice set of tools is the equivalent of IQ for a carpenter. But if he doesn’t put in the effort, take risks, make mistakes, and so on, he won’t become a good carpenter. On the other hand, someone with only a spoon and grit might still end up creating awesome pieces of woodcraft. I think this analogy is pretty visual.

The same applies to effort in isolation—it’s also not a good KPI. People who tried to build a perpetual motion machine spent a lot of effort, and some of them were pretty smart. It was still a waste of time.

So effort and intelligence are necessary but not sufficient conditions for success. We need to focus on objective achievements (what you’ve done that sets you apart). We don’t remember Einstein because he was a smart guy, but because of his specific contributions to science—and for sticking his tongue out in those funny pictures.

When I interview a candidate for a tech role, I put more weight on verifiable things you’ve done (conferences, GitHub repos, bug bounties, certifications, blogs, etc.) than on years of experience or standard education. I want proof of work that reflects passion and shows you can actually solve problems.

fluid vs crystalized intelligence

There are two types of intelligence: fluid 💧 and crystalized 💎.

Fluid intelligence is the raw problem-solving horsepower. It shoots up fast, hits its personal best around age 23, and then starts sliding downhill like my will to live after the third meeting of the day.

Crystallized intelligence, on the other hand, is all the stuff you’ve actually learned and stored. It climbs more slowly, peaks later at around age 35, and then declines at a gentler pace.

Here’s a cool chart made by my mate claude to illustrate both concepts over a lifespan:

bottom line

In my case, that blue curve peaked a decade ago and there’s nothing I can do about it. The orange one keeps climbing for another 30 years and that part is almost entirely on me. So the only variable I still control is the boring one: showing up and accumulating stuff.

But something has to turn the blue curve into the orange one, and in my case that mechanism has always been failed projects, and failing is just the build step nobody puts on their linkedin.

Keep grinding! 💪

1. yep, this deserves the linkedin cringy cliché ↩
2. still do, tbh ↩
3. sacrifycing the summer, ofc ↩
4. I can get quite obsessive sometimes ↩
5. which I will resume when I retire or something ↩
6. this was pre-llm without claude code, can you even imagine? ↩
7. He is also an expert in complex systems, a topic that fascinates me and I’ve talked about earlier in this very blog. ↩
