Appendix: A Consumer’s Guide to Brain Training Technology
(Or: What Your Money Buys)
The following represents a survey of currently available brain-training programmes and related cognitive enhancement technologies. This is not an endorsement—think of it more as field notes from the commercial wilderness. Prices and claims are as advertised by manufacturers as of early 2025, though by the time you read this, everything will probably have changed—because that’s how technology works.
Comprehensive Brain Training Platforms (The Full-Service Options)
BrainHQ (Posit Science)
-
Cost: $14/month or $96/year (less than a daily latte, as marketing materials helpfully point out—though you’ll notice they don’t compare it to things that actually improve cognitive function, like walking, which is free).

Also offers social interaction, community connection, and the satisfaction of supporting public institutions—shockingly underused given you’ve already paid for them through taxes.
-
YouTube Educational Content: Free, vast, ranging from brilliant to catastrophically misinformed. Requires the ability to distinguish legitimate education from conspiracy theories—which itself may count as cognitive training.
-
Community College Courses: Often free or low-cost for seniors. Provide real learning plus social engagement—far more enriching than clicking coloured shapes on a screen.
Critical Considerations for Consumers
(Or: How Not to Get Fleeced)
Red Flags That Should Send You Running
-
Claims about preventing or reversing dementia (no intervention has yet been proven to do this, full stop).
-
Promises of increased IQ or general intelligence (transfer effects are limited, and IQ is a questionable construct anyway).
-
Lack of published, peer-reviewed research (if they had legitimate research, they’d be shouting it from the rooftops).
-
Testimonials replacing evidence (“My aunt Gladys says it works” is not data).
-
Long-term subscriptions with unclear cancellation policies (always read the fine print, especially about auto-renewals).
-
Claims that sound too good to be true (because they are).
-
Anything involving electricity and your brain without medical supervision.
Questions to Ask Before Spending Money
-
What specific cognitive functions does this programme target? (Vague answers are red flags.)
-
What independent research supports its effectiveness? (Independent means not funded by the company.)
-
What’s the comparison group in the studies? (Active vs passive control matters enormously.)
-
How large are the demonstrated effects? (Statistically significant doesn’t mean practically meaningful.)
-
Do benefits transfer beyond the trained tasks? (The crucial question most companies avoid.)
-
How long do benefits last after training stops? (If you must keep paying to maintain them, perhaps question the model.)
-
Could I achieve similar benefits by walking, joining a book club, or learning the ukulele? (Honest answer: quite possibly, yes.)
The Reasonable Consumer’s Approach
If you choose to use brain-training programmes, approach them as you would any health intervention: with appropriate scepticism, realistic expectations, and a clear sense of cost–benefit. A $60 annual subscription to a research-backed programme represents minimal financial risk. Your dignity remains intact if you try it and decide it’s not worthwhile.
The time investment — typically 20–30 minutes daily — is a more significant commitment. Consider whether that time might be equally well spent on activities with proven benefits: physical exercise (improves cognition), social engagement (improves mental health and longevity), learning new skills (humans have been doing this successfully for millennia), or meaningful hobbies (purpose and satisfaction included).
The best cognitive intervention is the one you’ll actually maintain. If brain-training apps motivate you while book clubs don’t, use the apps. If you’ll actually take that Italian class but won’t touch a training programme, take the class. The perfect programme you don’t use is inferior to the adequate activity you actually do.
On the Subject of Expectations
Brain training will not make you a genius. It will not prevent dementia. It will not restore your 25-year-old processing speed. It may improve specific cognitive functions modestly. It may make you feel more in control of your cognitive health — which has value, even if the measurable benefits are small.
Most importantly, recognise that normal ageing involves some cognitive change — and that doesn’t necessarily require technological intervention. The goal isn’t to maintain the cognitive function of a 25-year-old indefinitely (that’s both impossible and, arguably, undesirable). Youth has advantages, but so does age: wisdom, perspective, emotional regulation, and the ability to see patterns across decades of experience — cognitive achievements no app can measure.
A Final Note on Marketing vs Reality
When brain-training companies show you graphs of improved performance, remember: that’s performance on their exercises. When they cite research, check whether it measured what you actually care about (remembering your grandchildren’s names, following complex conversations, maintaining independence) or what’s easy to measure in a lab (reaction time on abstract tasks).
When they invoke neuroplasticity — and they will, constantly — remember it’s a biological capacity we all have. It operates whether you’re using their programme or learning to bake sourdough. The question isn’t whether your brain can change (it can, it does, constantly) but whether their product produces changes worth paying for.
The Most Important Thing (Which Won’t Be in Any Marketing Materials)
Your brain is remarkable. It’s reading these words right now, forming opinions about whether this appendix is helpful or unnecessarily cynical. It’s managing your breathing, regulating your heart rate, processing sensory information, and probably thinking about what’s for dinner.
It’s got you this far through challenges and changes the 25-year-old version of you couldn’t have imagined — and it will keep adapting for the rest of your life, whether or not you subscribe to a brain-training programme.
The question isn’t whether your brain needs training. It’s what kind of life you want to live, and whether brain training supports that life — or merely provides the illusion of control.
Sometimes the most cognitively stimulating thing you can do is accept uncertainty, embrace interdependence, and focus on building a life rich in meaning, connection, and purpose, rather than optimising performance metrics that matter only to researchers and shareholders.
But if brain training makes you feel better and you can afford it — go ahead. Just keep your expectations realistic and your credit card limits reasonable.
A Postscript on Ageing Well (Free of Charge)
While researching this piece, I encountered a statistic the brain-training industry never mentions: according to international surveys, the happiest period of human life is around age 82. Happiness increases from the mid-50s onwards, as fear diminishes and gratitude grows.
This suggests that successful ageing has less to do with maintaining youthful cognitive metrics than with developing the psychological and social resources that make life satisfying. Brain-training programmes can’t teach wisdom, perspective, or contentment. They can’t help you build relationships, find purpose, laugh at yourself, or forgive old grievances.
These cognitive achievements of ageing — the ones that truly matter — emerge from living fully, not from completing daily exercises in isolation. They come from engagement with people, ideas, and activities that matter to you. From remaining curious while accepting your limitations. From continuing to grow, even as growth looks different at 70 than at 25.
The brain-training industry frames ageing as a problem requiring technological solutions. But perhaps ageing is better understood as a developmental stage with its own tasks and rewards — no more pathological than adolescence or middle age. The goal isn’t to preserve youthful processing speed, but to cultivate the mature forms of intelligence that only decades of experience can produce.
Your brain will age. That’s not failure — it’s biology. The question is whether you age in isolation, anxiously tracking metrics, or in community, pursuing meaning.
Brain-training programmes have their place, but that place is probably smaller than their marketing budgets suggest. The most important training your brain needs is the kind that comes from living a full, engaged, connected life — the kind humans have been practising successfully for thousands of years, long before anyone thought to turn it into an app with a subscription model.
So by all means, try brain training if it interests you. But also take walks. Join groups. Learn new things. Have conversations. Make art. Play games. Help others. Pursue interests. Build relationships. Laugh frequently. These activities train your brain while enriching your life — a better deal than optimising your reaction time on abstract tasks that bear little resemblance to anything you actually care about.
Your brain is plastic. Use that plasticity wisely.
